Mallorca 312: Training Guide
Three hundred and twelve kilometres around Mallorca in a single day.
The Mallorca 312 is one of Europe’s great mass-participation rides: a full lap of the island, roughly 312 km with about 5,000 m of climbing, almost all of it on closed or rolling-enclosure roads in late April. Shorter 225 km and 167 km routes share the start, but the 312 is the headline.
It is a road event, so drafting and group riding matter — but the day is decided by your ability to keep producing power after seven, eight, nine hours in the saddle. Finishing inside the time cutoffs is a real and worthy goal for most of the field.
What makes it hard
- Sheer duration. Most riders are out for 10–14+ hours. This is an all-day aerobic event, not a hard group ride.
- Front-loaded climbing. The Serra de Tramuntana passes come early, while you still feel strong — the discipline is to climb them well within yourself so you have legs for the long second half.
- The flat, exposed back half. After the mountains, a long coastal plain can turn into a battle with wind and fatigue, often ridden in thinning groups.
- Time cutoffs and the broom wagon. Intermediate cutoffs mean pacing and stops have to be managed, not improvised.
- Heat and fueling over a very long day — late-April Mallorca can be warm, and a long day magnifies any fueling mistakes.
What the day actually demands
The 312 is an aerobic endurance event with a road-racing surface. Your result is decided by how much sustainable power you still have deep into the ride, and by how cleverly you ride the groups — not by a big one-off climbing effort.
Climb the Tramuntana passes at an effort you could hold all day, not at threshold. Riders who chase wheels up the early climbs almost always pay for it across the long, flat, windy back half.
How to build toward it
Give yourself a real runway — 16 to 24 weeks suits most working athletes. The cornerstone is the long ride: progress it steadily toward 6+ hour days with real climbing in them, so both your engine and your contact points are ready for the distance.
Two or three quality rides a week is plenty: one long endurance ride, one sweet-spot or tempo session to lift sustainable power, and easy riding around them. Add some longer sustained climbs to your weeks if you can — the Tramuntana rewards riders who are comfortable at tempo for 20–40 minutes at a time.
Practise riding in groups and taking turns. On a road event of this length, sitting in and sharing the work efficiently can save you a great deal of energy for the part of the day that hurts.
Fueling and pacing: the real limiter
Over 10+ hours, fueling is decisive. Practise eating 60–90 grams of carbohydrate per hour on your long rides for weeks beforehand so your gut is trained, and know exactly where the feed stations are so you are never caught empty.
Have a pacing plan tied to the cutoffs: a target band for the climbs, a plan for finding groups on the flats, and stops that are short and deliberate. The clock is rarely lost on the road — it is lost standing still.
Equipment and conditions
This is a road bike day. Choose gearing that lets you spin the Tramuntana climbs comfortably late in the ride, not just when fresh — a generous climbing gear is worth far more at hour eight than a tall top end.
Pack for changeable spring mountain weather: descents off the passes can be cold even on a warm day. Always check the official site for the current year’s route, cutoffs, and start procedure, which shift from year to year.

Common questions
How long does it take to finish the Mallorca 312?
Most riders finish somewhere between 10 and 14+ hours, depending on fitness, conditions, and how the groups form. The leaders are far faster, but for the bulk of the field the day is about steady, well-fueled riding inside the cutoffs.
Do I need to do the full 312, or is the 225 or 167 a better goal?
For many riders the 225 km or 167 km routes are an excellent and serious goal in their own right, and a sensible stepping stone. Pick the distance that matches your training history and the runway you have, and step up when your long rides say you are ready.
Course distance, elevation, and dates shift year to year. Always confirm the current year's details on the official event site — Mallorca 312. This guide is general training information, not coaching advice tailored to you.
