You have an event circled on the calendar. The Etape du Tour. The Marmotte. The Maratona dles Dolomites. Maybe a local gran fondo that someone at the club mentioned — and before you had time to think about it properly, you said yes and put your money down. You have told people. Your partner knows. Your colleagues know. There is a date, a distance, and a mountain profile that you have probably looked at more times than is healthy.
And now the questions start. Not the training questions — those come later. The real questions. The ones that sit behind the confident face you put on when someone asks how the prep is going. Can I actually do this? What happens when I get to hour four and my legs go? What if I am the slowest rider on the road?
Here is the good news. Every single person lining up for their first gran fondo has these same questions. Every one of them. And the answers are not complicated. They are specific, they are practical, and they are all fixable. This guide covers the things nobody tells you before your first big event — the pacing mistakes that ruin the day, the cycling nutrition decisions that make or break the final third, the kit choices that actually matter, and the mental tools that get you over the last climb when your brain is telling you to stop.
What a gran fondo actually is
Let me be really clear about this, because the terminology confuses people. A gran fondo is not a race. Not for most riders. It is also not a casual charity ride where you potter along at conversation pace and collect a medal for turning up.
A gran fondo sits between a sportive and a road race. It is timed. There are feed stations. There are climbs that will test everything you have trained for. There is a finishing time printed on a results sheet, and yes, you will look at it. Some riders race — particularly on the timed climbs where certain events award a polka-dot jersey or a KOM classification. But the vast majority ride their own pace, eat at the feed stations, suffer on the cols, and cross the line with a finish time they can measure themselves against.
The difference from a standard UK or Irish sportive is mostly one of scale and culture. Sportives tend to run 80-160km with modest climbing. A gran fondo — particularly the big Italian, French, and Spanish ones — runs 120-200km with 2,000-4,000m of vertical. The culture is different too. European gran fondos are community events. Entire towns shut down. Feed stations serve pasta and cured meats, not energy bars handed through a car window. You ride alongside 8,000 other people, and the atmosphere on the start line is closer to a marathon than a time trial.
The riders who enjoy it most are the ones who understood all of this before the start line. It is not a race. But it is a serious test. And treating it seriously in training means you get to enjoy the day instead of merely surviving it.
Realistic training timelines
Sixteen weeks. That is the minimum I would recommend for a first-timer taking on a gran fondo of 150km or more with meaningful climbing. If your longest ride right now is under 60km, add four weeks of base on top of that. Twenty weeks total. It sounds like a lot. It is not.
Here is how the 16 weeks break down, and why each phase matters.
Phase 1: Base building (weeks 1-4)
The first four weeks are about aerobic capacity. Long, controlled rides at a pace that feels almost too easy. Professor Stephen Seiler's polarised training research — discussed at length on the podcast — shows that amateur riders consistently ride too hard on their easy days and too easy on their hard days. For a fondo build, your base rides should sit below 75% of FTP. If you do not know your FTP, test it in week one and set your zones using the FTP Zone Calculator.
Build your longest ride from 2 hours to 3.5-4 hours across this phase. One quality midweek session — tempo or sweetspot — keeps the system ticking. Everything else is genuine zone 2. This is not exciting training. It is the training that makes everything after it work.
Phase 2: Progressive build (weeks 5-12)
Eight weeks of progressive overload. Volume rises. Intensity sharpens. The long ride grows toward 70-80% of your event distance — so if your fondo is 160km, you want to be hitting 110-130km on your biggest training days.
The sessions that matter most in this phase are sustained threshold efforts (2x20 minutes at 95-100% FTP) and long tempo blocks inserted into the Saturday ride. Dan Lorang, who has coached Pogacar and Vingegaard, has said on the podcast that long sustained efforts at threshold are the highest-return session for endurance athletes preparing for events over three hours. The adaptation is specific and it transfers directly to what a gran fondo demands.
Every fourth week, drop volume by 30-40%. Keep one quality session. This is a recovery week, and skipping it is how riders arrive at the start line already tired.
Phase 3: Sharpening and taper (weeks 13-16)
Volume comes down. Intensity stays sharp. Week 13 and 14 are the hardest weeks of the entire block — short, aggressive VO2 sessions (5x4 minutes at 110-115% FTP) combined with race-simulation long rides at event pace. Week 15 cuts volume by 25%. Week 16 is taper proper: short openers, nothing heavy, trust the work you have done.
The full week-by-week breakdown is in the 12-week gran fondo training plan. If you have 16 weeks, use the first four as the base phase described above and then roll into that 12-week structure.
Pacing — why starting too fast ruins everything
This is the single biggest mistake first-timers make. And here is where it gets really interesting — it does not feel like a mistake when you are making it.
The start line of a gran fondo is electric. There is music, there is nervous energy, there are thousands of riders clipping in around you. The gun goes and the group surges. Your heart rate spikes. You settle in behind some wheels, the road opens up, and the first 30 minutes feel effortless. You are riding 10-15 watts above your plan and you do not notice because it feels easy. The legs are fresh. The crowds are cheering. The adrenaline is doing its job.
Then hour three arrives. And everything you borrowed in the first 30 minutes comes due with interest.
Here is what the data tells us. A rider who starts at 80% of FTP instead of 70% will accumulate roughly 15-20% more fatigue by the midpoint of the event. On a flat road, that is manageable. On a gran fondo with three major climbs in the second half, it is the difference between riding the final col and walking it.
The fix is simple in theory and brutally hard in practice: pace the first 90 minutes at 65-70% of FTP. This feels slow. Riders will pass you. Let them. The riders you let go in the first hour are almost always the ones you pass on the final climb. Joe Friel makes this point in every long-distance racing conversation — the discipline to hold back early is the single variable that separates riders who finish strong from riders who survive.
Set your FTP zones before the event. Write your target power range on a piece of tape stuck to your stem. Look at it every 15 minutes for the first two hours. When in doubt, back off 5 watts. You will thank yourself at kilometre 130.
Nutrition on rides over four hours
Here is the thing nobody tells you about gran fondo nutrition. For the first three hours, almost everyone is fine. You eat a gel, drink some water, the feed stations arrive on schedule, and you feel strong. Then hour four hits. And nutrition stops being a background task and becomes the entire event.
A 5-hour ride at moderate intensity burns 3,000-4,000 calories. Even at the upper end of carbohydrate absorption — 80-90g per hour — you are running a significant calorie deficit. The riders who planned their nutrition survive this deficit. The riders who winged it bonk, and bonking in hour five of a gran fondo with 30km still to ride is an experience you do not want.
The numbers that matter
Target 60-80g of carbohydrate per hour. Not from hour three when you start feeling hungry — from minute one. Your body processes fuel on a delay. The gel you eat at the 30-minute mark is fuelling you at the 90-minute mark. Start late and you are already behind.
Use a mix of sources. Gels for convenience and speed. Bars for something to chew on during the flatter sections. Real food from the feed stations — a banana, a piece of cake, whatever looks good and sits well. The Fuel Planner will build a per-hour target based on your bodyweight and ride intensity. Use it.
Water versus electrolytes
Plain water is not enough for a ride over three hours. You need sodium, potassium, and magnesium to maintain muscle function and prevent cramping. Two bidons per refill — one with electrolyte, one with plain water. The hydration calculator gives you a per-hour fluid target based on temperature and effort.
The gut needs training
Here is where first-timers consistently get caught. You cannot eat 80g of carbs per hour on event day if you have never done it in training. The gut is a trainable organ. Start practising your fuelling plan at least six weeks before the event. Do your long Saturday ride with the same gels, bars, and electrolyte mix you plan to use on race day. If something causes stomach problems at kilometre 60 in training, you have time to change it. If it causes problems at kilometre 60 of the Marmotte, you have 80km of misery ahead of you.
No new food on race day. No new gels. No new energy drink. Nothing you have not tested in training at least twice.
What to do when the legs go
Everyone hits a wall. This is not a sign that your training was wrong or that you are not fit enough to be there. It is a normal physiological response to prolonged exercise, and it happens to nearly every rider on events over four hours.
The bad patch usually arrives between hours three and five. The legs feel heavy. The power drops. Your brain starts constructing arguments for why stopping is reasonable. The climb ahead looks impossible. The feed station 12km away might as well be 120km away.
Here is what to do.
First, slow down. Not to a crawl, but by 10-15%. Drop from 70% FTP to 60%. Shift into an easier gear and let the cadence come up. The effort should feel properly easy — so easy that a small part of you feels embarrassed about it. Good. That is the right effort.
Second, eat. 40-60g of fast-acting carbohydrate. A gel, a handful of sweets from your pocket, a can of cola from the feed station. Sugar is not the enemy here. Sugar is the intervention. Your glycogen stores are depleted and your blood sugar is dropping. Carbohydrate is the fix, and it works within 15-20 minutes if you give it a chance.
Third, keep the pedals turning. The worst thing you can do during a bad patch is stop completely. When you stop, your muscles stiffen, your heart rate drops, and getting going again feels ten times harder than it did before you unclipped. Keep moving, even at 15kph. Even on a false flat. Keep the chain turning over.
The bad patch passes. It nearly always does. Twenty to thirty minutes of easy spinning, some food, some fluid, and the legs come back. Not to where they were at hour one — but enough to finish. Enough to ride the last climb. Enough to cross the line on your bike instead of in a broom wagon.
The mental game on long climbs
The first time you see a 12km climb on your bike computer — the kind with a gradient that sits at 7-8% and just does not stop — your brain will tell you it is impossible. It is not impossible. It is long. Those are different problems, and they need different solutions.
Break the climb into thirds
Bottom third: hold back. This is where the pacing discipline from earlier in the ride matters most. The bottom of a climb feels manageable because you are fresh relative to what is coming. Ride it 5-10% below what you think you can sustain. If your target is 200 watts, ride at 185. You will need those 15 watts later.
Middle third: survive. This is the hardest section mentally because the gradient does not change, the summit is not visible, and the riders around you are suffering too. Settle into a rhythm. Pick a cadence — 70-75rpm is a good target for most riders on sustained gradients — and hold it. Do not look at the gradient. Do not look at the distance remaining. Look at your power and your cadence and the road 50-100 metres ahead of you.
Final third: you can see the top. This is where the riders who paced the bottom start to pull away from the riders who attacked it. If you have anything left, this is where you use it. But if you do not, that is fine too. Keep the same cadence, keep the same power, and ride the climb to the top.
Counting pedal strokes
This sounds strange until you try it. When the suffering peaks and your brain is screaming at you to stop, count pedal strokes. One to fifty, then start again. It occupies the conscious mind with something other than pain. It forces you to focus on the immediate action — turning the pedals — instead of the remaining distance. Cyclists who have done long Alpine climbs will tell you this works. It does. Try it on a training climb before the event so you trust it when you need it.
Use the climb time estimator to set realistic targets for the major ascents on your event. Knowing that a 12km climb at 7% will take you 48 minutes at 200 watts is far better than staring at a gradient profile and wondering. Specifics remove fear. Vague dread is always worse than a number.
Kit choices that actually matter
This is the section where I tell you that the thing you are thinking about buying will not help you, and the thing you are not thinking about will.
Chamois cream
More important than carbon wheels. More important than an aero helmet. More important than whatever upgrade the bike shop is selling you this week. Five hours in the saddle with inadequate chamois cream produces saddle sores, chafing, and a level of discomfort that makes the climbing and the fatigue feel trivial by comparison. Apply it generously before the start. Carry a small pot in your back pocket for a reapplication at the halfway feed station. This is not optional.
Saddle comfort
If you have not done a ride over four hours on your current saddle, do one before the event. Not two weeks before. Six weeks before, minimum. A saddle that feels fine at 90 minutes can become a torture device at 240 minutes. If there are pressure points or numbness at four hours, change the saddle or get a bike fit. This is fixable — but only if you find it in training.
Bibs over shorts
Bib shorts hold the chamois pad in place and distribute pressure across your shoulders instead of your waist. For rides over three hours, the difference is significant. If you are still wearing waist-band cycling shorts, switch to bibs for the event. Your lower back and your contact points will thank you.
Rain jacket
Pack one even if the forecast is clear. Mountain weather changes. A descent at 60kph in wet kit at altitude will drop your core temperature faster than anything else in cycling. A lightweight packable jacket weighs 100g and fits in a jersey pocket. The weight penalty is zero. The insurance is enormous.
Tyre pressure
This matters more than tyre brand, more than wheel depth, and more than frame material. Over-inflated tyres bounce on rough road surfaces and waste energy. Under-inflated tyres increase rolling resistance and risk pinch flats. The tyre pressure calculator gives you a target based on your weight, tyre width, and road conditions. Run it the night before and set your pressures in the morning.
Gear ratios
If your event has Alpine climbs — anything over 8% for extended periods — check that your gearing can handle it. A 34x32 cassette is the bare minimum for most riders on gradients above 10%. If you are currently running a compact chainset with an 11-28 cassette, you will grind to a halt on a 12% hairpin in hour five. The gear ratio calculator shows your available ratios and the cadence you will be pedalling at a given speed. If the numbers say 45rpm on the steepest section, fit a wider cassette before the event, not at the event.
Logistics and travel
The 48 hours before a gran fondo matter more than most riders realise. Not because you can gain fitness — you cannot, the hay is in the barn — but because you can lose it through poor logistics.
The day before
Do a short easy spin. 30-45 minutes, nothing more. Enough to loosen the legs after travel, check the gears shift cleanly, and confirm the brakes work. Do not go sightseeing on foot. Walking 15,000 steps around a beautiful Italian town the day before a 160km fondo is a leg-draining mistake that looks harmless until you feel it at kilometre 100.
If you can, pre-ride the last 5km of the course. Knowing what the finish looks like — where the final turn is, whether it is uphill or flat, how the road surface changes — removes one more unknown on event day.
Sleep
Sleep in a familiar bed if at all possible. If not, bring your own pillow. This sounds absurd. It is not. Sleep quality the night before an endurance event is strongly correlated with performance, and sleeping in a strange bed with a strange pillow in a room that is too hot or too cold is a variable you can control.
You will not sleep well the night before. Accept this. The sleep that matters is two and three nights out. Prioritise those.
Food
Eat what you know. The night before is not the time for a three-course Italian dinner with wine and a dessert you have never tried. Pasta, protein, vegetables, water. Boring. Familiar. Effective. Your pre-ride meal — 3 hours before the start, 60-80g of carbohydrate — should be something you have eaten before every long training ride. Porridge with honey and a banana. Toast with peanut butter. Whatever works for you, replicate it exactly.
Registration and event morning
Collect your number the day before if the event allows it. Morning registration queues are long, stressful, and eat into your warm-up time. Pin your number to your jersey the night before. Charge your bike computer. Fill your bidons. Lay out your kit. Reduce the morning to a series of automatic steps, not decisions.
Arrive at the start with 30-45 minutes to spare. Warm up on the turbo if you have one, or do a 15-minute easy spin on the road. Use the toilet. Top up your bidons. Eat your pre-ride snack 30 minutes before the gun. Then line up. Not at the front — in the middle or toward the back. The front is for the riders who are racing. You are not racing. You are riding.
The social element
Here is the part that nobody mentions in training plans and power-meter articles. A gran fondo is a social event. And the social element is half of what makes it worth doing.
On a training ride, you are alone with your numbers. On a gran fondo, you are surrounded by thousands of riders who are all doing the same thing you are doing — testing themselves against a course, a distance, and their own preparation. There is a solidarity in that which is difficult to describe until you experience it.
Chat on the climbs. When the gradient bites and the pace drops below 15kph, the rider next to you is suffering exactly as much as you are. Say hello. Ask where they are from. Talk about the gradient. Share a gel. These tiny interactions carry you further than 10 extra watts ever will.
Ride with a group when you can. Sitting in a wheel at 30kph on a flat section saves 20-30% of your energy compared to riding alone. That is not cheating. That is cycling. Find a group going your pace in the first hour and share the work. When the climbs come and the group splinters, ride your own effort. When the descent finishes and the road flattens, find another group. This is how a gran fondo works.
The feed stations are part of the experience. Stop. Eat. Fill your bidons. Stretch your back. Talk to the volunteers. Take 5 minutes, not 5 seconds. The riders who sprint through every feed station to save 3 minutes on their finishing time are missing the point. The feed station is where the event lives — the atmosphere, the camaraderie, the slightly bizarre experience of eating pasta at 11am on a mountain pass surrounded by 200 riders in lycra.
And the finish line. When you cross it — and you will cross it — the feeling is different from anything you have experienced in training. The distance is done. The climbs are behind you. The hours of preparation, the early morning rides, the sessions you did not want to do but did anyway — all of it lands in a single moment when you roll across that line. Your time does not matter. You finished. That is the achievement.
You are ready for this
The riders who enjoy their first gran fondo are not the strongest, the lightest, or the ones with the most expensive bikes. They are the ones who trained consistently, paced the first hour with discipline, fuelled properly, expected the bad patch, and kept pedalling through it. That is the formula. It is not complicated. It is specific.
Train for 16 weeks. Pace at 65-70% FTP. Eat 60-80g of carbs per hour, starting from the gun. Apply the chamois cream. Pack the rain jacket. Break the climbs into thirds. Count the pedal strokes when it hurts. Slow down when the legs go. Eat. Drink. Keep moving.
And when you cross that finish line — when you sit down with a cold drink and look at the mountains you just rode over and the distance you just covered — you will understand why people do this again and again. It is not about the time. It is about proving to yourself that you could.
If you are preparing for your first event and you want the structure, the accountability, and a community of riders who have been exactly where you are right now, the Not Done Yet community on Skool is where that conversation starts. Riders preparing for the Etape, the Marmotte, the Maratona — they are all in there, sharing training, comparing race plans, and asking the questions this article answered. You do not have to do this alone.
