Ötztaler Radmarathon: Training Guide
Four Alpine passes, 5,500 metres up. The one-day climb that defines a season.
The Ötztaler Radmarathon is one of the most revered single-day road events in cycling: roughly 227 kilometres around the Tyrolean Alps with about 5,500 metres of climbing, stacked into four big passes — Kühtai, the Brenner, the Jaufenpass, and the Timmelsjoch — all ridden back-to-back in a single day from Sölden.
For most of the roughly four-thousand-strong field this is the hardest day on a bike they will do all year, and simply finishing it is the achievement. The clock matters less than getting over the final climb, the Timmelsjoch, with something left — because that is where the day is won or lost.
What makes it hard
- Total climbing. Around 5,500 m of ascent in one ride means most riders are out for the better part of a day; the question is how long you can keep climbing well, not how hard you can climb once.
- The Timmelsjoch finale. The last pass tops out at about 2,474 m and is climbed after roughly 190 km already in the legs — a long, high ascent reached when you are most empty. Riders who overspend early fall apart here.
- Sustained, not punchy. Each pass is a long, steady grind of 15–30+ km. Your sustainable climbing power over hours is the limiter, not your sprint.
- Altitude and alpine weather. The high passes sit above 2,000 m where weather changes fast — heat low down, cold, wind or rain up top, and long exposed descents in between.
- Getting a place at all. Entry is famously by lottery, so even reaching the start line takes planning a season ahead.
What the day actually demands
The Ötztaler is an aerobic endurance climbing event above all else. With four long passes and only short valley sections between them, your result comes down to how durable your sustainable climbing power is at hour seven — not how big your one-minute punch is. Train the engine, and train it on hills.
Pacing is the whole game. Every climb tempts you to push because the gradients are steady and rideable, but the smart effort is conservative on the first three passes so the Timmelsjoch is survivable. Treat the Brenner and Jaufenpass as setup for the final climb, not as places to make time.
How to build toward it
Give yourself a real runway — 16 to 24+ weeks is realistic for most working riders, and the build needs to be climbing-led. Your weekend long rides should accumulate serious vertical, progressing toward 5–7+ hour days with several thousand metres of ascent so your legs learn to keep climbing when tired.
Two or three quality rides a week is plenty: one long climbing endurance ride, one session of sustained tempo or threshold done on a climb to lift the power you can hold for 30–60 minutes, and easy spinning around them. If you live somewhere flat, long sweet-spot intervals and big-gear work stand in for mountains — but get to real climbs before race day if you possibly can.
Back-to-back climbing weekends late in the build teach your body to perform on tired legs, which is exactly the state the Timmelsjoch will find you in.
Fueling and hydration: the long-day limiter
A day this long is fed, not just ridden. Practise taking in 60–90 grams of carbohydrate per hour on your long rides for weeks beforehand so your gut is trained to absorb it — bonking on the Jaufenpass with the Timmelsjoch still to come is a long way from home.
Plan your refills around the feed stations and the long climbs, and rehearse eating while cold and tired, not just when fresh. On a cool alpine day your sense of thirst drops but your energy demand does not, so keep eating and drinking on a schedule rather than by feel.
Gearing, descending, and alpine weather
Gear for the mountains, not your local rolling roads. Most finishers run easier gearing than they think they need — a compact or sub-compact chainset with a wide cassette — so they can spin the long passes at a sustainable cadence rather than grinding their legs out early.
The descents matter too: there are long, fast drops between the passes where bike handling and confident cornering save energy and time. And pack for cold. Even in summer the high summits can be cold, wet, or windy, so a packable layer for the descents off the Jaufenpass and Timmelsjoch is not optional — chilling on a 20-minute descent wrecks the legs for the next climb. Check the official site for the current route, cut-off arrangements, and any weather guidance.

Common questions
How long does it take to finish the Ötztaler Radmarathon?
It varies enormously with fitness and weather, but for much of the field it is an all-day effort in the region of eight to eleven-plus hours of riding. The leaders are far faster; for most riders the goal is to keep moving steadily and get over the Timmelsjoch before the cut-offs. Check the official site for the current year’s time limits.
How do I get a place in the Ötztaler Radmarathon?
Entry is allocated by lottery rather than first-come registration — you register your interest in a set window (typically early in the year) and starting places are drawn among applicants. There are usually also combined accommodation-and-start-place packages for riders who miss the draw. The official event site has the current registration dates and rules.
How much climbing is in the Ötztaler, and how do I train for it?
Around 5,500 m of ascent across four passes. The best preparation is climbing-led: progress your long rides toward 5–7+ hour days with several thousand metres of vertical, and do your hard sustained efforts on climbs rather than the flat. If you live somewhere flat, long sweet-spot intervals and big-gear work help, but try to get onto real mountains before race day.
What gearing should I run for the Ötztaler Radmarathon?
Most non-professional finishers choose easier gearing than for a typical sportive — commonly a compact or sub-compact chainset with a wide-range cassette — so they can spin the long alpine passes at a sustainable cadence instead of grinding. Being able to sit and turn the pedals on the Timmelsjoch is worth far more than a slightly higher top gear.
