The Amstel Gold Race Tourtocht follows the roads of cycling's only Dutch Monument through South Limburg — a pocket of the Netherlands that looks nothing like the flat polders most people associate with Dutch cycling. The long route covers roughly 250km with 3,000 metres of climbing, packed into 35-plus short, steep hills that arrive without warning, punish you for 60-120 seconds, and disappear into the next valley before you have recovered. Fifteen thousand riders line up each April. Most of them discover that the hills are not the problem. The frequency is.
This is the training framework we use with riders inside Not Done Yet who are targeting the Amstel Gold sportive and comparable rolling-terrain events. The sessions, pacing strategy, and fuelling advice are built around the specific demand that defines South Limburg — not climbing, but the repeated capacity to accelerate, recover, and accelerate again across an eight-to-eleven hour day.
What Makes the Amstel Gold Race Sportive Different
The hills. South Limburg's caubergs and hellingen are short. The Cauberg itself is 1.2km. The Keutenberg is 700 metres. The Eyserbosweg is 1.5km. None of these would merit a second glance on an Alpine profile. But they are steep — 6-10% average with ramps that touch 12-22% — and they arrive in clusters. Three hills in 8km, a false flat for 5km, two more hills, a descent, another hill. The cumulative vertical is 3,000m, which is substantial, but it is distributed across 35-plus individual efforts rather than four sustained climbs. Your body never settles into a climbing rhythm. Every hill is an acceleration from rolling speed to threshold-or-above, followed by a descent or flat where you are trying to recover before the next one hits.
The rhythm. This is what catches riders out. An Alpine sportive has clear structure: climb for 45 minutes, descend for 15, ride a valley for 30, climb again. You can pace around known efforts of known duration. Amstel Gold has no such structure. The hills arrive unpredictably — some visible from a distance, others around a blind corner. You shift from big ring to small ring dozens of times across the day, and the constant gear changes create a metabolic cost that steady-state riding does not. Your heart rate oscillates between Zone 2 and Zone 5 all day, with no sustained period in any single zone. By hour seven, even modest hills feel vicious because your neuromuscular system has been absorbing repeated shocks since morning.
The roads. South Limburg's roads are narrow — often single-track width through the hills, hemmed by hedgerows or brick walls, with poor sightlines around corners. In a sportive with thousands of riders, this creates bottlenecks at the base of every climb. Positioning matters. If you arrive at the foot of the Keutenberg in the middle of a dense group, you lose momentum waiting for riders ahead. Experienced Amstel riders move to the front before each climb and commit from the first metre. The narrow descents demand equal respect — wet roads, tight bends, riders of mixed ability ahead. You recover by soft-pedalling at controlled pace, not by freewheeling at speed.
The weather. Mid-April in South Limburg is spring in name only. Average temperatures sit between 6 and 14 degrees Celsius. Rain is likely more often than not. The terrain alternates between sheltered valleys and exposed agricultural plateaux where crosswinds sweep across the road unimpeded. A day that starts dry at 12 degrees can deteriorate to 6 degrees with rain and wind chill by the afternoon, and on a 250km route that means hours of riding in conditions that sap morale and body heat simultaneously. Riders who dressed for the forecast at the start line are frequently underdressed by kilometre 180.
The Key Climbs: Know What You Are Facing
Cauberg (1.2km, 6.5% average, 12% maximum)
The Cauberg is the most famous climb on the course because it decides the professional race. For the sportive, it is not the hardest hill — but it is the most symbolic, and it arrives late in the day when your legs are carrying the accumulated fatigue of 30-plus earlier efforts. The average gradient of 6.5% is manageable, but the final ramp kicks to 12% and the road narrows as it enters the town of Valkenburg. Ride it at 90-95% FTP. Do not attack the Cauberg as if it were the finale — unless it actually is your last hill, there are more to come. The climb time calculator will show you what your current power numbers translate to on 1.2km at 6.5%.
Keutenberg (700m, 9.4% average, 22% maximum, cobbled)
The Keutenberg is the hardest single effort on the course. It is the only cobbled climb in the Amstel Gold sportive and the combination of gradient, surface, and brevity makes it a genuine test. The first 200 metres are steep tarmac. Then the cobbles begin, the gradient ramps to 15-22%, and for the next 40-50 seconds you are fighting for traction, momentum, and composure on a surface that actively resists you. Power demand: 130-150% FTP for 60-90 seconds. Seated riding gives better traction on the cobbles but the gradient forces most riders out of the saddle on the steepest section. If you stand, shift your weight rearward to keep the rear wheel loaded. Losing traction here means losing momentum, and restarting on a 22% cobbled gradient is brutally hard.
Eyserbosweg (1.5km, 7.2% average)
Longer than most Limburg hills and consistently steep. The Eyserbosweg does not have a single savage ramp — instead, it grinds at 7-8% for a kilometre and a half through woodland, which is long enough to demand proper pacing rather than a sprint-and-survive approach. Target 88-93% FTP and hold it. This climb punishes riders who attack the first 500 metres and fade. The VAM calculator will show that your vertical speed on a 7% gradient at threshold is modest — roughly 900-1,100m/hour for most amateurs — which is useful context for pacing the effort.
Camerig (1.4km, 6.8% average)
The Camerig is a grinding effort on an exposed road with a steady gradient and no real recovery points. It is not spectacular, but it represents the bread-and-butter cauberg that defines the Amstel experience: 3-5 minutes of sustained work at 90-100% FTP, just long enough to hurt, just short enough that you think you can recover before the next one. Multiply this by 25 and you have the Amstel Gold sportive in miniature.
Bemelerberg (900m, 5% average)
The Bemelerberg is one of the easier climbs on the route and its position matters more than its gradient. It arrives after a series of harder hills and serves as a gauge: if the Bemelerberg at 5% feels comfortable, your pacing is correct and your fuelling is working. If 5% at kilometre 190 feels desperate, you have been riding the earlier hills too hard or eating too little. It is a reality check, not a crux.
Fitness Benchmarks
The Amstel Gold sportive rewards a specific fitness profile. High sustained W/kg matters less than the ability to produce repeated short efforts and recover between them. A rider with modest FTP but strong 1-minute power handles the caubergs far better than a stronger rider whose short-power curve drops off.
| Capacity | Strong Finish | Comfortable Finish | Completion | |----------|--------------|-------------------|------------| | FTP | 3.0+ W/kg | 2.5-3.0 W/kg | 2.0-2.5 W/kg | | 1-minute power | 7+ W/kg | 5.5-7 W/kg | 4.5-5.5 W/kg | | 5-second sprint | 12+ W/kg | 9-12 W/kg | 7-9 W/kg | | Endurance ride | 6+ hours | 5-6 hours | 4-5 hours |
The 1-minute row is the most predictive. A rider with 3.5 W/kg FTP and 5 W/kg for 60 seconds will suffer on every cauberg from kilometre 150 onward, because each hill demands a spike well above threshold and the recovery window is too short to fully clear the debt. A rider with 2.8 W/kg FTP but 7 W/kg for 60 seconds rides the same hills within their capacity and recovers faster between them.
Check your FTP zones and identify where the gap is. If your endurance base is strong but your short power is poor, the build phase should weight toward neuromuscular and VO2max work. If your 1-minute power is solid but you fade after four hours, the base phase needs more volume and longer rides.
The 16-Week Training Structure
This plan targets a mid-April event. The 16-week block starts in late December — winter base training that builds into spring-specific preparation. The emphasis throughout is endurance first, repeated short-power work second. Riders who train only intensity and neglect the 250km distance reality arrive at the event with sharp legs and no fuel to run them.
Phase 1: Base (Weeks 1-6)
Volume: 8-12 hours per week. Four to five rides. 80% in Zone 2.
The base phase for the Amstel sportive looks like any endurance build — long rides, aerobic volume, steady progression — with one distinction. Short neuromuscular efforts appear from week one. The caubergs demand a specific muscular recruitment pattern: rapid acceleration from rolling speed, high force production for 30-90 seconds, then immediate recovery at moderate intensity. That pattern needs early neural adaptation, not just aerobic conditioning.
Weekly structure:
- 3-4 Zone 2 rides (1-2 hours midweek, longer on weekends)
- 1 quality session: sweet spot intervals, 2x20 minutes at 88-93% FTP
- 1 long ride building from 3 hours (week 1) to 5 hours (week 6), on rolling terrain where possible
- Include 4-6 short sharp efforts (20-40 seconds at 150%+ FTP) in two rides per week — any gradient, from a standing start or rolling start
- 1-2 strength sessions: lunges, single-leg press, step-ups, Bulgarian split squats, core stability — build the single-leg strength that repeated steep accelerations demand
Key metric: By week 6, a 5-hour ride on rolling terrain should feel controlled, not heroic. Your legs should finish tired, not destroyed. If you are emptied after five hours, the distance of 250km will break you regardless of how sharp your 1-minute power is. Track your training stress score — CTL should be climbing 3-5 points per week through this phase.
Phase 2: Build (Weeks 7-12)
Volume: 10-14 hours per week. This is where the training starts looking like the event.
Two quality sessions per week, long rides extending to 6-7 hours, and at least two sessions per week that specifically replicate the cauberg rhythm. The build phase is the engine room of this plan.
Weekly structure:
- 2 quality sessions (see below)
- 2-3 Zone 2 rides
- 1 long ride building to 6-7 hours on rolling terrain with 1,500-2,000m of climbing
- 1 maintenance strength session
Quality session 1 — cauberg simulation intervals. After a 20-minute warm-up, ride 10-15 repetitions of a short steep hill (60-120 seconds at 120-150% FTP, 3-5 minutes rolling recovery between efforts). The recovery must be active — not coasting, not stopped, but riding at 65-75% FTP on rolling terrain. This is the signature session. The Amstel Gold rhythm is hard-easy-hard-easy across the entire day, and your body must learn to clear the lactate, stabilise the breathing, and produce power again within three to five minutes.
Build from 8 reps in week 7 to 15 reps by week 11. If you live somewhere flat, use overgeared standing starts, bridge ramps, or indoor trainer intervals set at 12-15% gradient for 90 seconds with 4 minutes at 2-3% recovery.
Quality session 2 — rolling tempo with surges. 75-100 minutes at 70-80% FTP with 8-12 surges to 120-130% FTP for 30-60 seconds every 5-8 minutes. This simulates the Limburg terrain — tempo riding punctuated by the sudden acceleration a cauberg demands. Vary the surges: some seated in a big gear at 60 RPM, others at 90+ RPM out of the saddle. The caubergs come in different gradients and lengths, and your body needs to handle both torque-based and cadence-based efforts.
The long ride. By weeks 10-12, your long ride should reach 6-7 hours on the hilliest terrain available. Include full race-day fuelling — 60-80g of carbs per hour from start to finish. These rides are not about intensity. They are about time, distance, and the adaptations that happen beyond hour five: improved fat oxidation, gut tolerance at sustained carbohydrate intake, saddle comfort, and the mental capacity to keep riding when the work has long stopped being fun.
Back-to-back weekends. Twice in the build phase, ride a 5-hour Saturday with cauberg intervals followed by a 3-hour Sunday at steady tempo. Starting Sunday's ride on tired legs teaches your body what kilometre 200 of the Amstel feels like — making power when the legs insist they have nothing left.
Phase 3: Sharpen (Weeks 13-14)
Volume: 9-11 hours per week. The fitness is built. These two weeks refine it.
Quality session 1 — race simulation. A 3-4 hour ride on the hilliest terrain you can find with 15-20 cauberg-effort surges embedded throughout. Ride the flat sections at race tempo (70-80% FTP) and attack every hill at race intensity (110-140% FTP). This is a dress rehearsal. Use your race-day gearing, race-day nutrition, race-day clothing. The power-speed calculator can help frame what your target watts translate to in terms of speed on specific gradients — useful for setting realistic expectations for race day.
Quality session 2 — short and sharp. 60-75 minutes with 6-8 efforts of 30-60 seconds at 150%+ FTP with full recovery. These are neuromuscular maintenance sessions — keeping the top end alive while the body absorbs the training load of the build phase.
Long ride: One ride of 5-6 hours at aerobic pace with a handful of cauberg efforts. This is the last significant volume session before the taper begins.
Phase 4: Taper (Weeks 15-16)
Volume drops 30-40% in week 15, 50% in week 16. Keep short sharp efforts to maintain neuromuscular responsiveness — 4-6 efforts of 30-60 seconds at 140-150% FTP with full recovery. Remove volume, not intensity. The taper sheds fatigue while keeping the fast-twitch recruitment patterns that the caubergs demand.
Week 15: 3-4 rides, 6-8 hours total. One ride of 3-4 hours at aerobic pace with 5-6 cauberg efforts. One short threshold session (2x10 minutes at 92-97% FTP).
Week 16: 2-3 rides, 4-5 hours total. Openers two days before the event — 60-75 minutes with 4 efforts of 30-45 seconds at race intensity. Rest. Eat. Sleep.
A proper taper for a 250km event is worth 3-5% in performance terms. Your legs will feel restless and agitated in the final days. That is the fatigue lifting. Trust it.
Climbing Technique for the Caubergs
Power gets you up the hills. Technique determines how much that power costs.
Gradient transitions
The caubergs are short but they often begin abruptly — flat road into 8% within 20 metres, sometimes around a corner. The gradient transition is the moment most riders lose efficiency. They hit the ramp in their big ring, their cadence crashes, and they scramble to downshift while losing momentum.
Anticipate. Shift before the gradient arrives. If you can see the hill — or if you know from the route profile that one is coming — move to the small chainring and a mid-cassette gear 50 metres before the base. Arriving at the gradient in the right gear with momentum preserved is worth 5-10 seconds per hill. Over 35 hills, that accumulates.
Seated versus standing
On the caubergs, seated climbing is more efficient for gradients up to about 10%. Beyond that, most riders need to stand — not for power, but because the gradient forces your centre of mass too far back for effective pedalling while seated. The exception is the Keutenberg, where standing on cobbles risks traction loss. On cobbled gradients, stay seated as long as physically possible and shift your weight forward on the saddle to keep pressure on the rear wheel.
For tarmac caubergs, alternate between seated and standing within a single effort if the gradient allows it. Twenty seconds standing to change muscle recruitment, then back to seated for the final push. This distributes the load across more muscle groups and delays localised fatigue — a technique that matters far more at hill number 30 than at hill number 5.
Cadence management
The natural tendency on a short steep hill is to grind: drop the cadence, stand, and force the pedals over. This works for three hills. By hill fifteen, the muscular cost of grinding at 55 RPM has accumulated into a fatigue that no amount of aerobic fitness can offset. Target 70-80 RPM on the tarmac caubergs where the gradient permits. This shifts the load toward cardiovascular capacity, which recovers faster between efforts than muscular force does. On the steepest pitches — the Keutenberg, the sharp ramps on the Eyserbosweg — cadence will drop to 55-65 RPM regardless of gearing. Accept it on those. Everywhere else, spin.
Gearing
The Keutenberg at 22% on cobbles is the gearing challenge. Every other climb on the course is rideable with standard road gearing, but the Keutenberg demands low ratios and the willingness to use them.
Run a compact crankset (50/34). On the rear cassette, a 30-tooth is the minimum. A 32-tooth is better insurance and the weight penalty — roughly 40 grams — is meaningless across a 250km day. Here is the practical calculation: a 75kg rider on the Keutenberg (22% gradient) at 34x30 and 60 RPM produces roughly 380 watts and travels at 5.5kph. At 34x28, the same cadence requires approximately 410 watts. At kilometre 180, when the Keutenberg arrives after six hours of riding, those 30 watts are the difference between riding the cobbles and walking them. Use the gear ratio calculator to check your specific setup against the key gradients.
Swap your cassette by week 4 of the plan at the latest and train on the gearing you will race. Leg speed on a 34x30 at 60 RPM on a steep gradient is a specific neuromuscular pattern that needs time to feel natural. An 11-30 or 11-32 cassette with a compact chainset is the standard Amstel Gold setup — the outer ring covers the flats and descents, and the 34-tooth inner ring handles every cauberg on the course.
Fuelling for a Long, Rolling Day
The constant acceleration-and-recovery pattern burns glycogen faster than steady-state riding at the same average power. Every cauberg spikes your intensity above threshold, depleting glycogen stores disproportionately. By hour six, if you have underfuelled, the hills that were manageable at hour two become walls — not because the gradient changed, but because your fuel did.
Target: 60-80g of carbohydrate per hour from kilometre one. Use the fuelling calculator to plan exact quantities based on your bodyweight and expected duration. Higher intake within the range if conditions are cold, because cold suppresses appetite and riders consistently eat less than they think they do.
Drink mix as primary fuel. On a course with 35+ hills, the practical windows for eating are short — the 3-8km rolling sections between climbs. Liquid calories in the bottle require no unwrapping, no chewing, no timing. Mix bottles to 40-50g of carbohydrate per 500ml and aim for one bottle per hour. Supplement with gels on the flat sections and solid food at feed stops.
| Hour | What to Eat | Notes | |------|------------|-------| | 1-3 | Drink mix (40-50g/hr) + 1 bar or gel per hour | Eat aggressively while absorption is strong and terrain allows | | 4-6 | Drink mix + mix of gels and bars between hills | Vary textures to prevent flavour fatigue — sweet, savoury, salty | | 7-8 | Drink mix + gels primarily | Gut function declining — eat what you know works, nothing new | | 9+ | Liquid carbs and gels, small frequent doses | Survival fuelling — anything that stays down counts |
Hydration. April temperatures mean lower sweat rates than a summer event, but you are still losing fluid — especially during the repeated high-intensity cauberg efforts. Target 500-600ml per hour. Add 400-600mg of sodium per litre. Cold conditions suppress the thirst response just as they suppress appetite. Drink to schedule, not to thirst. The hydration calculator will frame the numbers against your bodyweight and the forecast conditions.
Pre-race. 8-10g of carbohydrate per kg of bodyweight the day before. Breakfast 3-4 hours before the start: 2-3g/kg of carbs, moderate protein, low fibre, low fat. A 250km day burns 5,500-7,000 kcal for a 75kg rider. You will not replace all of it on the bike. The goal is to start with full glycogen stores and close the deficit enough that fat oxidation and on-bike fuelling cover the rest.
Weather Preparation
Mid-April in South Limburg is unreliable. The terrain amplifies the problem — the valleys are sheltered but damp, the plateaux are exposed to wind, and the constant climbing and descending means your body alternates between sweating on the hills and cooling rapidly on the descents.
Baseline expectation. Temperature: 6-14 degrees Celsius. Rain: probable on at least half the editions. Wind: 15-30kph, predominantly westerly, with exposed crosswind sections on the agricultural roads between hills. Use the wind chill calculator to translate the forecast into feels-like temperatures — at 8 degrees with a 25kph headwind, the perceived temperature drops to roughly 3 degrees.
What to wear. Thermal base layer, arm warmers, and a gilet as minimum. Pack a lightweight rain jacket and wear it before you are cold, not after. Full-length gloves if the forecast suggests rain or temperatures below 10 degrees. Shoe covers if below 8 degrees. The descents between caubergs are where cold accumulates — you are wet from climbing, the wind hits on the descent, and body temperature drops fast. Layering correctly is a performance decision, not vanity.
Train in cold wet conditions. If your base and build phases fall in January through March, ride outdoors in bad weather regularly. At least one ride per week in whatever cold or wet conditions your geography provides. The physiological adaptations — improved vasoconstriction, better core temperature regulation — are real. So are the practical lessons: which gloves actually work, which jacket breathes, which shoe covers keep your feet dry beyond two hours. Race day is not the time to find out your wet-weather setup fails.
Race Day Pacing
The fundamental error is riding the first third too hard. The hills arrive early and the legs are fresh, so riders attack every cauberg at full intensity, adrenaline masking the cost. By kilometre 160, those early expenditures come due. The riders who paced the opening 80km conservatively are the riders who ride the final 80km rather than surviving it.
Kilometres 1-80: Discipline. Stay in a group. Ride the flats at 65-75% FTP. Attack nothing. When caubergs arrive — and they will, from the first 15km — ride them at 100-115% FTP, no more. This feels easy. It should feel easy. You have 170km and 25 more hills ahead. Eat and drink from the first kilometre. Position yourself well before each hill but do not race for position. Your job in the first third is to arrive at the middle third with full glycogen stores, controlled heart rate, and fresh neuromuscular reserves.
Kilometres 80-170: Controlled effort. The middle section is where the ride begins. The hills are steeper, the frequency increases, and the accumulated fatigue starts to colour every effort. Ride the caubergs at 110-130% FTP. Recover properly between them — drop to Zone 1-2 on the rolling sections, eat, drink. The Keutenberg likely falls in this section. Give it what it demands — 130-150% FTP on the cobbles — but accept the cost and recover fully afterward. Do not chase riders up every hill. The position you gain by attacking the Camerig at 140% FTP is not worth the three hills you lose 15km later because you could not recover.
Kilometres 170-250: Truth. The final third is where the training either holds or it does not. The Cauberg, the Bemelerberg, and the last cluster of hills arrive on legs that have been working for seven or eight hours. Give each hill what you have, not what you had at kilometre 50. If 110% FTP is your ceiling at kilometre 200, that is your ceiling. Trying to match the power you produced at kilometre 40 is how riders crack and walk hills they could have ridden. Keep eating. Keep drinking. Maintain 60-70% FTP between hills. The finish line rewards consistent pacing across 250km, not heroics on any single cauberg.
Frequently Asked Questions
These are the questions we hear most from riders inside Not Done Yet who are preparing for the Amstel Gold sportive.
Do I need to recce the course? Helpful but not essential. The route is well-signed and the caubergs are short enough that profile knowledge does not change your effort significantly. What recce gives you is familiarity with gradient transitions — knowing that the Keutenberg cobbles begin 200 metres in, knowing where the Cauberg kicks, knowing which descents are technical. If you can ride 100-150km of the course at moderate intensity during a training weekend in February or March, that is the best possible preparation.
How does this compare to Liège-Bastogne-Liège? Both feature repeated short climbs and demand the same fundamental fitness. Liège is longer (273km versus 250km), has more elevation (4,000m versus 3,000m), and its côtes are slightly longer. Amstel's hills are shorter, steeper on average, and more frequent. Liège tests endurance more; Amstel tests acceleration more. The pacing and fuelling principles overlap substantially.
Should I use a power meter? Yes, if you have one. The value is not during the hills — when a 15% gradient arrives, you ride it at whatever power the gradient demands. The value is between the hills. Keeping your recovery effort below 75% FTP in the rolling sections prevents the slow bleed of energy that turns the final third into survival. Heart rate lags too far behind the constant intensity changes to be useful as a primary pacing tool on this course.
Is strength training important for this event? Yes, but not heavy barbell work. The repeated acceleration pattern demands single-leg strength and hip stability. Lunges, Bulgarian split squats, step-ups, single-leg press, and core stability work build the muscular resilience that repeated standing accelerations on steep gradients require. Two sessions per week in the base phase, one in the build phase. Stop strength work two weeks before the event.
What if I bonk at kilometre 180? If you reach kilometre 180 and the wheels have come off — legs empty, every 4% gradient feeling impossible — the cause is almost certainly underfuelling in hours 1-5. Stop at the next feed station, eat aggressively (400-600 calories of whatever is available — Coca-Cola, cake, sandwiches, gels), sit for 10 minutes, and restart at 60% FTP. You will not recover fully but you will recover enough to finish. The time cost of a 10-minute stop is less than the time cost of riding the final 70km at 15kph because you refused to stop. Prevention is better: eat 60-80g of carbs per hour from kilometre one and do not skip a single feeding window because you felt fine at hour three.
