The Gran Fondo Il Lombardia is the sportive version of cycling's most beautiful Monument. Il Lombardia — the Race of the Falling Leaves — closes the professional season in October, and the gran fondo sends amateur riders through the same Lombardy hills above Lake Como. 160km. Approximately 4,000m of climbing. The Civiglio, San Fermo della Battaglia, and a series of lesser-known climbs that would be the hardest thing on most sportive calendars but here are just the terrain between the signature efforts.
The course does not care that Lake Como is stunning. The autumn colours are extraordinary. The lakeside roads are cinematic. And while you are admiring them, the road tilts upward again and stays there for another 4km at 8%.
Here is the thing nobody tells you about this event: the October date is the defining characteristic, not the climbs. By October, you have been riding since March or April. Your legs carry seven months of accumulated fatigue. The riders who arrive fresh — who periodised properly and treated this as their end-of-season peak rather than an afterthought tacked onto a summer already full of events — are the riders who ride the Civiglio. Everyone else survives it.
This guide follows the framework we use with riders inside Not Done Yet who are targeting the Gran Fondo Il Lombardia and comparable late-season mountain sportives. The training is built around sustained climbing power, the pacing accounts for the density of the climbing, and the preparation acknowledges that October demands different planning than a June event.
Key Takeaways
- The Gran Fondo Il Lombardia covers approximately 160km with 4,000m of climbing through the hills above Lake Como — the climbing density is relentless, with few flat kilometres to recover.
- The Civiglio is the race-defining climb: 4.2km at 9.6% average with sections touching 15%. It arrives late in the day when the legs are already hollow.
- San Fermo della Battaglia at 2.7km and 7.5% average is the final sting — riders who emptied themselves on the Civiglio crawl up San Fermo.
- Target 3.2 W/kg minimum for a finish inside cut-offs; 4.0+ W/kg to ride the major climbs at steady threshold and finish in the front half.
- October weather in Lombardy is unpredictable — morning fog on the lakeside, warmth in the valleys, cold rain above 800m. Layering is not optional.
- A 14-week build with sustained climbing intervals (20-40 minutes) and back-to-back long-ride weekends simulates the event's demand of climbing on pre-fatigued legs.
- The descents around Lake Como are technical, narrow, and occasionally wet with fallen leaves — descending confidence saves more time than climbing watts at this event.
What the Gran Fondo Il Lombardia Actually Demands
The numbers first. Approximately 160km with roughly 4,000m of climbing. That puts it in the same vertical bracket as the Granfondo Stelvio, but the climbing is distributed differently. The Stelvio concentrates its elevation into one massive ascent. Il Lombardia spreads it across eight to ten climbs of varying length and gradient, with short descents and false flats between them. The result is a course where you are almost always climbing, descending, or about to do one of the two. True flat kilometres are rare. Recovery happens on the bike, not on the road.
The climbing density. This is what separates Il Lombardia from most Italian gran fondos. The Maratona dles Dolomites has big passes separated by long valley roads. Nove Colli alternates its climbs with genuine flat sections through Romagna. Il Lombardia rarely lets you breathe. The terrain above Lake Como is rumpled, steep, and unforgiving — the moment you finish one climb and begin the descent, you can see the next climb across the valley.
The key climbs:
- Civiglio (4.2km, 9.6% average, max 15%): The signature effort. A narrow road climbing through chestnut trees above Bellagio with a brutal opening kilometre that ramps to 15% before settling into sustained 9-10% for the remainder. This is where the professionals attack. This is where the gran fondo is decided.
- San Fermo della Battaglia (2.7km, 7.5% average): Shorter, apparently less severe, but arriving after the Civiglio and 140+ kilometres of racing. The gradient is honest and steady. Your legs are not. Riders who rode the Civiglio five watts too hard discover the cost on San Fermo.
- Ghisallo (8.5km, 5.6% average): The famous climb to the Madonna del Ghisallo chapel, patron saint of cycling. The gradient is moderate by Lombardy standards, but the length and its position in the route build fatigue that compounds later.
- Colma di Sormano and the Muro di Sormano: The professional race sometimes includes the Muro — a 2km wall averaging 15% with sections above 25%. The gran fondo route varies by year, but the Colma di Sormano (7.4km, 6.4% average) often features and is a substantial effort with a steep final kilometre.
October conditions. This is not a summer sportive. October in Lombardy means morning temperatures of 8-12 degrees Celsius in the valleys, mist hanging over Lake Como until mid-morning, afternoon warmth of 16-20 degrees if the sun appears, and the ever-present possibility of cold rain. Above 800m, temperatures drop further. The roads through the hills above the lake are shaded by chestnut and beech trees — beautiful in their autumn colours, but those falling leaves sit on tarmac and turn wet corners into something close to ice. Riders from northern Europe and the UK will recognise the conditions. Riders who have only raced in Italian summer will not.
How it compares. The Gran Fondo Il Lombardia is harder than the Maratona dles Dolomites in climbing density per kilometre. It is comparable to Nove Colli in total difficulty but with steeper individual gradients. It is less total elevation than the Otztaler but the gradients are sharper. The October date adds a dimension that no other major Italian gran fondo shares — you are not arriving in peak summer form. You are arriving at the end of a season. That distinction changes everything about how you prepare.
Course Analysis: Where the Event Is Won and Lost
Opening 50km: The Lakeside Deception
The first section runs through the Lake Como basin. Rolling roads, lakeside stretches, groups forming. The gradient is gentle. The pace feels comfortable. This is where people make their first mistake.
The lakeside kilometres are deceptive because they feel flat but are not. There are constant 2-3% drags, short ramps, and small rollers that individually cost nothing but collectively start the clock on your glycogen stores. Riders who get drawn into fast group riding through this section — chasing wheels, surging on the small rises, riding 10-15 watts above plan — arrive at the first real climb with a deficit they will pay for at kilometre 130.
Ride this section at 60-65% FTP. Eat. Drink. Stay in a group but do not chase. The event starts later.
50-100km: The Middle Climbs That Drain Reserves
The course moves into the hills properly. Climbs of 4-8km at 5-7% average arrive with increasing frequency. None of them are individually terrifying. The Ghisallo is long but moderate. The Colma di Sormano is steady. Other route-specific climbs vary by year but follow the same pattern: 5-8% for 4-8km, short descent, another ramp.
This is where discipline separates the finishers from the survivors. Each of these climbs needs to be ridden at 80-85% FTP. Not 90%. Not threshold. The temptation is to ride them at tempo-plus because the gradient allows it and the legs feel strong. Riders who do this are writing cheques that the Civiglio will cash.
The middle section is also where fuelling must be aggressive. You are burning 600-800 calories per hour on the climbs and the descents are too short and too technical for comfortable eating. Eat on the lower slopes. Eat at the summit. Eat on any flat section. By kilometre 100, you need to have consumed at least 300-350g of carbohydrate. Use the fuelling calculator to plan your hourly targets.
100-140km: Civiglio and the Selection
The Civiglio arrives somewhere between kilometre 120 and 135, depending on the year's route. By now you have been riding for five to seven hours. You have climbed 2,500-3,000m. Your glycogen stores are depleted no matter how well you fuelled. Your legs are carrying the cumulative fatigue of every climb that came before.
The first kilometre of the Civiglio is the steepest — gradients touching 14-15% on a narrow road. This is where the event fragments. Riders who paced the middle section correctly can ride this opening ramp at 90-95% FTP and settle into the remaining 3km at a hard but sustainable effort. Riders who arrived at the Civiglio already in the red simply cannot respond to the gradient. They grind. They zigzag. They stop.
Let me break this down. The Civiglio at 9.6% average for 4.2km takes roughly 18-25 minutes depending on fitness. For a 75kg rider at 3.5 W/kg, that is 18 minutes at approximately 260 watts after 130km of racing. The same rider at full freshness would manage that effort comfortably. After 130km and 3,000m of climbing, it is a completely different physiological proposition. The fatigue penalty is real — expect to lose 5-10% of your sustainable power compared to fresh-legs output, and pace accordingly.
Pacing the Civiglio: Start the opening steep section at RPE 8, not 9. Let the steepest gradient dictate a lower speed rather than spiking power to maintain pace. Once the gradient eases to 8-9% after the first kilometre, settle into 88-92% FTP. Keep cadence above 65 RPM — if it drops below 60, you are in the danger zone for cramping. Do not stand unless you must. Seated climbing is more economical here because you have no matches left to burn.
140-160km: San Fermo and the Descent to the Finish
San Fermo della Battaglia comes after the Civiglio descent. It is 2.7km at 7.5% average — shorter, less steep, apparently less demanding. It is not. San Fermo is where the Gran Fondo Il Lombardia is cruellest, because it arrives when you have nothing left and it asks for another 12-15 minutes of honest climbing.
Ride San Fermo at 80-85% FTP. Accept that it will feel harder than that number suggests. Keep the pedals turning. Do not look at the gradient on your head unit — it does not help.
The descent from San Fermo toward the finish is fast, technical in places, and potentially wet. Tired hands on brake levers, tired concentration on corners, and the adrenaline of finishing can combine badly. Descend within your limits. The finish line is not going anywhere.
14-Week Training Framework
The 14-week structure works backward from an October event date, placing the start of the plan in early-to-mid July. This matters: you begin the plan in summer, which means the early weeks coincide with good weather, long daylight hours, and ideally some climbing availability.
Weeks 1-4: Base with Climbing Emphasis (8-10 hours/week)
The base phase is not about building fitness from scratch — you have been riding all season. It is about resetting the body, clearing accumulated fatigue from summer events, and establishing the climbing-specific endurance that the Lombardia demands.
Weekly structure:
- 2 recovery rides (60-90 minutes, Zone 1-2)
- 1 tempo ride with climbing (90 minutes, 2x20 minutes at 85% FTP on gradient)
- 1 weekend long ride (4-5 hours, hilly terrain, Zone 2 with natural climbing efforts)
The priority in weeks 1-4 is climbing volume, not climbing intensity. Ride hills. Ride them steadily. Accumulate 1,500-2,000m of climbing per week across all sessions. If you live on flat terrain, use an indoor trainer set to 6-8% gradient simulation for the tempo sessions.
Weeks 5-8: Build with Sustained Threshold Climbs (10-12 hours/week)
This is where the specificity begins. The build phase targets the exact physiological demand of Il Lombardia: sustained power output on gradients of 6-10% for 15-40 minutes, repeated across a long day.
Weekly structure:
- 1 recovery ride (60-90 minutes, Zone 1-2)
- 1 interval session: 3x20 minutes at 92-97% FTP on gradient (5 minutes recovery between)
- 1 over-under session: 4x12 minutes alternating 2 minutes at 105% FTP / 2 minutes at 85% FTP
- 1 weekend long ride (5-6 hours, 2,000-2,500m climbing, tempo on climbs)
- 1 optional midweek endurance ride (90-120 minutes, Zone 2)
Use the FTP zones tool to set your training numbers precisely. The 3x20-minute session is the anchor of the build phase — it simulates the sustained effort of the middle climbs. Progress to 3x25 minutes by week 7, then 2x30 minutes plus 1x20 minutes by week 8.
Weeks 9-12: Peak with Race-Simulation Weekends (10-12 hours/week)
The peak phase introduces back-to-back long-ride weekends and end-of-ride climbing efforts that simulate the demands of riding the Civiglio after 130km.
Weekly structure:
- 1 recovery ride (60 minutes, Zone 1)
- 1 key interval session (varies — see Key Sessions below)
- Weekend block: Saturday 4-5 hours with 2,000m climbing at tempo, Sunday 3-4 hours with end-of-ride threshold climb efforts
The back-to-back weekend is the most important training stimulus in the plan. Saturday's ride pre-fatigues the legs. Sunday's ride asks you to climb hard on those pre-fatigued legs. This is the closest simulation of what the Civiglio feels like at kilometre 130. Run at least three back-to-back weekends in this phase.
Weeks 13-14: Taper
Reduce volume by 40-50%. Maintain one short intensity session per week — 2x10 minutes at 95% FTP on gradient — to keep the legs sharp. The rest is recovery rides and rest days.
The taper for an October event carries an additional consideration: you are likely tired from the full season. If you feel flat in week 13, that is not a fitness problem — it is an accumulated fatigue problem. Trust the taper. Sleep more. Eat well. The fitness is in the legs. It just needs the fatigue to clear.
Key Sessions That Simulate the Event's Demands
These are the sessions that transfer most directly to the demands of Il Lombardia. Run them during the build and peak phases.
Civiglio Simulation: 3x20 minutes at 95-100% FTP on gradient. Find a climb of 5-8% gradient. Ride 20 minutes at 95-100% FTP, descend for 5 minutes, repeat. Progress from 3x15 to 3x20 to 2x25 + 1x20 across the build phase. This is the bread and butter of Il Lombardia preparation — sustained climbing power on gradient, repeated, with insufficient recovery.
Over-Under Climbing Intervals. 4x12 minutes on gradient: 2 minutes at 105% FTP, 2 minutes at 85% FTP, alternating through the 12-minute block. 4-minute recovery between sets. These train the ability to absorb surges on steep sections and recover without stopping — exactly what the Civiglio's variable gradient demands.
End-of-Ride Climbing Efforts. Ride 3-4 hours at endurance pace with 1,500m of climbing. In the final 45 minutes, ride 2x15 minutes at 92-95% FTP on the steepest gradient available. This session teaches your body to produce threshold power when the legs are already carrying significant fatigue. It is uncomfortable. It is also the single most specific session for the Civiglio.
Technical Descending Practice. This is not an interval session. It is a skill session. Find a technical, twisting descent — ideally with tight corners, variable road surfaces, and some tree cover. Ride it repeatedly. Practice braking before corners rather than through them. Practice looking through the exit of each turn. Practice riding a consistent line on damp tarmac. The descents around Lake Como are narrow, technical, and in October they are covered in wet leaves. The riders who descend confidently save 5-10 minutes across the event and, more importantly, stay in contact with groups. The riders who brake at every corner ride alone.
Nutrition and Fuelling Strategy
The Gran Fondo Il Lombardia is a 6-9 hour effort depending on fitness and conditions. At that duration, fuelling is not supplementary to training — it is equal to it. The best climber in the world walks up the Civiglio if they bonk at kilometre 110.
Target: 70-90g of carbohydrate per hour from the start. Use the fuelling calculator to set your exact numbers against bodyweight and expected finish time.
The October conditions change the fuelling equation compared to summer events. You sweat less in cooler temperatures, which means lower fluid and sodium losses, but it also means reduced thirst drive. Riders in 14-degree conditions drink less than riders in 28-degree conditions — not because they need less fluid, but because the body's thirst response is blunted by the cold. Dehydration in autumn creeps up silently. Drink on schedule, not on thirst.
Hourly plan:
| Hour | What to Eat | Notes | |------|------------|-------| | 1-2 | Drink mix (40-50g/hr) + 1 bar per hour | Appetite is good, stomach is settled, eat solid food now | | 3-4 | Drink mix + gels + feed zone food | Transition to easier-to-digest sources as intensity builds | | 5-6 | Gels, drink mix, feed zone food | Keep carbs flowing — this is the window before the Civiglio | | 7+ | Gels, cola, liquid carbs | Gut tolerance drops — use whatever stays down |
Pre-race carb loading. 8-10g of carbohydrate per kg of bodyweight the day before. Breakfast 3 hours before the start: 2-3g/kg carbs, moderate protein, low fibre. The Italian dinner the night before is part of the experience — pasta, bread, and a quiet reminder that the body stores approximately 2,000 calories of glycogen and you are about to burn 4,000-6,000.
Autumn-specific hydration. In cooler conditions, target 500-750ml per hour rather than the 750ml-1,000ml you would drink in summer. But do not drop below 500ml. The work rate is the same even if the temperature is not. Sodium intake can be slightly lower — 400-600mg per litre — but should not be neglected entirely.
Train the fuelling plan on at least four long rides before the event. Your gut needs to practise processing 70-90g of carbs per hour under racing effort. This is trainable. It is not optional.
Kit and Equipment Considerations
Gearing. The Civiglio at 15% maximum gradient and San Fermo at 7.5% average after 140km of riding demand low gears. A compact crankset (50/34) with a 32 or 34-tooth cassette is the minimum recommendation. Riders below 3.5 W/kg should run 34x34 without hesitation. The Civiglio's steep opening ramp at the end of a 130km day will expose any gearing shortfall — use the FTP zones tool to calculate your sustainable power and check your cadence at 15% gradient with your planned gearing.
Tyres. October conditions mean wet roads, fallen leaves, and reduced visibility. Run 28mm tyres minimum — 30mm if your frame allows it. Tubeless is strongly preferred for the puncture protection and lower rolling resistance. Drop tyre pressure by 5-10 PSI compared to your summer setup: 70-75 PSI for a 75kg rider on 28mm tubeless gives better grip on wet leaf-covered corners without meaningful rolling resistance penalty.
Autumn layering. The temperature range across the event can span 15 degrees — 8 degrees at the start, 20 degrees in sheltered valleys at midday, 12 degrees on exposed hilltops. Layer for it:
- Base layer: merino wool or high-quality synthetic, not cotton
- Arm warmers: essential, removable if the sun appears
- Gilet: packable, windproof, goes on for descents and off for climbs
- Full-finger gloves: cold fingers cannot brake properly on 6km descents
- Knee or leg warmers: consider the conditions — if rain is forecast, full leg warmers
Pack the gilet and arm warmers every single time. Even if the forecast says dry and mild. October in Lombardy changes its mind.
Lighting. Late October means shorter days. The event starts early and if you are in the 8-9 hour bracket, you may be finishing in fading light. A small rear light is prudent. A front light weighs 50 grams and costs nothing in performance but might matter on a shaded descent at 5pm.
Race Week and Race Day Logistics
Travel to Bergamo. Bergamo Orio al Serio airport is the nearest hub, well served by European low-cost carriers. Milan Malpensa and Milan Linate are alternatives. The Lake Como area is 60-90 minutes from Bergamo. Book accommodation early — the event coincides with the professional Il Lombardia weekend and the area fills quickly. Bellagio, Como, and Lecco are all viable bases depending on the start location.
Pre-race reconnaissance. If you arrive a day or two early, ride the Civiglio. Not at race pace — at 60-70% FTP, sitting up, looking at the gradient changes, noting the surface quality, memorising the steep opening ramp. Knowing what is coming removes the psychological shock on race day. The San Fermo is also worth a casual ride. Twenty minutes of reconnaissance saves you five minutes of panic.
Morning routine. An October start means darkness. Get up 3 hours before the gun. Eat your pre-race meal — practised, familiar, carbohydrate-heavy. Pin your number. Check your layers. Check the weather one final time. Warm up on the turbo for 15-20 minutes if one is available, or ride easy to the start and include 3-4 short efforts of 30 seconds to open the legs.
Pacing plan across the major climbs:
| Climb | Target Effort | Pacing Notes | |-------|--------------|--------------| | Early-route climbs (km 30-80) | 78-83% FTP | Stay patient. These feel easy. They are meant to. | | Ghisallo / mid-route climbs | 82-87% FTP | Steady tempo. Eat at the top of every climb. | | Colma di Sormano | 85-90% FTP | The last climb before the Civiglio. Do not empty yourself here. | | Civiglio | 88-95% FTP | Survive the opening ramp. Settle into 90% FTP. Keep cadence above 65 RPM. | | San Fermo | 80-87% FTP | Whatever is left. Keep turning the pedals. |
Common Mistakes Riders Make at Gran Fondo Il Lombardia
Arriving end-of-season tired instead of fresh. This is the most common and most damaging mistake. Riders treat Il Lombardia as the final event on a calendar already packed with sportives, training camps, and club racing. They arrive with accumulated fatigue from a full season, no taper, and wonder why the Civiglio breaks them. The fix is straightforward: plan the season with Il Lombardia as the October peak. Reduce event participation in September. Taper properly. Arrive fresh.
Underestimating the Civiglio gradient. 9.6% average with sections at 15% does not read as extreme on paper — plenty of climbs in the Alps are steeper. But the Civiglio's severity is contextual. It arrives after 130km and 3,000m of climbing. At that point in the day, 9.6% average with a 15% opener is a different proposition from the same gradient at kilometre 10. Train for it specifically. If your local area has nothing above 7%, use an indoor trainer set to 12-15% gradient and ride 5-minute efforts at the end of long sessions.
Treating it like a summer sportive. Wrong kit. No gilet. Short-finger gloves. No leg warmers. Summer tyres at summer pressures. October in Lombardy can deliver sunshine, but it can also deliver cold rain, fog, and temperatures that drop 8 degrees in the time it takes to climb 400 metres. Riders who dress for summer and get October weather lose time, lose morale, and risk hypothermia on the descents.
Descending too cautiously — or too aggressively. This one cuts both ways. Riders who brake at every corner on the Como descents lose contact with their groups, ride alone for the rest of the day, and lose 10-15 minutes to more confident descenders. Riders who attack wet, leaf-covered corners with summer aggression crash. The answer is practised, confident, controlled descending — the kind that comes from skill sessions, not from bravery. If your descending is weak, fix it in September. Not on race day.
Not eating enough through the middle section. The middle climbs feel manageable. The descents are short and technical, so eating feels awkward. The result is a fuelling gap between kilometre 50 and kilometre 100 where riders consume 40-50g of carbs per hour instead of 70-90g. By the time the Civiglio arrives, they are 150-200g of carbohydrate behind their plan. That deficit is the difference between riding the Civiglio and walking it. Eat aggressively in the middle section. Eat on the lower slopes of every climb. Eat at every summit. Force it if necessary.
The Event Within the Event
The Gran Fondo Il Lombardia is the last great sportive of the European season. By October, the Alps are closing, the Dolomite passes are approaching their winter shutdown, and the cycling calendar is winding down. Il Lombardia stands at the end of all of it — 160km through the most beautiful cycling terrain in northern Italy, on roads that have decided Monument champions for over a century.
The riders who finish well are the ones who respected the event enough to plan for it specifically. Not as an add-on. Not as the final weekend of a tired season. As a peak event that demands a proper build, a proper taper, and the discipline to ride the first 120km within themselves so that the Civiglio is hard but rideable.
If you are building toward Il Lombardia and want specific session programming, pacing plans, and the experience of riders who have ridden it — Not Done Yet is where that work happens.
