HOW DO YOU TRAIN FOR ALPINE CLIMBS?

By Anthony WalshRoadman CyclingUpdated 10 July 2026

ANSWER

Training for alpine climbs from flat terrain centres on three qualities: sustained threshold power for 20-60 minute efforts, fatigue resistance so your output holds after three hours in the saddle, and climbing-specific muscular endurance. Build a 12-week block with long rides of 3-5 hours at endurance pace, weekly threshold intervals of 2x20 minutes building to 3x20, and one weekly session of low-cadence force work at 60-65 rpm on the steepest local gradient you can find.

KEY TAKEAWAYS

Train threshold power with 2x20-minute intervals building toward 3x20 over 12 weeks.
Build fatigue resistance with long rides that include a hard effort in the final 90 minutes.
Low-cadence force reps at 60-65 rpm on hills mimic the muscular demands of steep alpine roads.
Simulate altitude stress with heat training if you live at sea level — 60-90 minutes in a hot room, 10+ sessions.

WHO THIS IS FOR

IS THIS YOU?

The flatlands rider going to the mountains

You live somewhere without significant hills and have a mountain sportive or cycling holiday booked.

The rider preparing for the Etape or Marmotte

You have a specific big-mountain event on the calendar and want a structured preparation block.

THE ROADMAN VIEW

You can train for alpine climbs from the Netherlands if you structure it properly. The physical demands of a 40-minute col are not mysterious — you need the power to hold 85-90% of FTP for a long time, the endurance base to do it after three hours in the saddle, and the muscular tolerance for low-cadence grinding that steep gradients force on you.

The part most flat-terrain riders underestimate is the cumulative fatigue. It is not the first climb that breaks you — it is the fourth, after 100km and 2,500m of ascending. Training sessions that put a hard effort at the end of a long ride are more specific than fresh 2x20 intervals, because they teach your body to produce power when glycogen is running low and the legs are already loaded.

EXPERT EVIDENCE

WHAT THE EXPERTS SAY

Dr Iñigo San MillánExercise physiologist, UAE Team Emirates performance director
Successful climbing preparation at sea level requires a combination of sustained threshold work and volume. The aerobic base determines how much of your threshold you can access after three hours of riding — without it, top-end power is irrelevant because you cannot reach it when fatigued.

PRACTICAL APPLICATION

DO THIS WEEK

Build threshold duration progressively
Weeks 1-4: 2x15 minutes at 90-95% FTP. Weeks 5-8: 2x20 minutes. Weeks 9-11: 3x20 minutes. The goal is extending how long you can hold near-threshold power, not pushing the ceiling higher.
Add end-of-ride intensity
Once a fortnight, extend your long ride by 30 minutes and include 2x10 minutes at tempo in the final hour. This trains the specific fatigue resistance that alpine days demand — hard efforts on tired legs.
Simulate climbing with low-cadence force reps
On the steepest local hill or on a turbo trainer at high resistance, do 6x3 minutes at 60-65 rpm, zone 3-4 intensity, with 3 minutes easy between. This builds the muscular endurance for sustained low-cadence climbing.

COMMON MISTAKES

WHAT CYCLISTS GET WRONG

MISTAKEFocusing exclusively on short, high-intensity intervals.
FIXAlpine climbs last 20-60 minutes. Train the duration, not the intensity. A 5-minute VO2max interval is valuable for general fitness but does not replicate the sustained demand of a 45-minute col.
MISTAKENeglecting fuelling practice during long training rides.
FIXYou will need 60-90g of carbohydrate per hour during a mountain day. If your gut is not trained for this intake, race day is not the time to find out. Practise your nutrition strategy on every long ride.
MISTAKEArriving in the mountains and trying to ride hard on day one.
FIXIf your event is at altitude, arrive 2-3 days early and keep the first two days easy. Altitude reduces your effective FTP by 5-15% depending on elevation — you need time to recalibrate your effort.

FAQ

FREQUENTLY ASKED QUESTIONS

Can you train for mountains if you live somewhere flat?

Yes. Threshold intervals, long rides, and low-cadence force work on a turbo trainer replicate the physical demands effectively. Bridges, overpasses, and car park ramps also work for short repeated climbs. The preparation is less romantic than riding actual mountains, but it works.

How many weeks do you need to prepare for an alpine event?

A minimum of 12 weeks of structured preparation, assuming you already have a reasonable aerobic base. If you are starting from scratch, allow 16-20 weeks. The final two weeks should include a taper to arrive fresh.

Should I lose weight before a mountain event?

Only if you have weight to lose without compromising power. Losing muscle or under-fuelling to cut a kilogram will cost you more power than the weight saves. Focus on training and nutrition quality; body composition follows.
