Mallorca 312 2027: how to prepare the 312, 225 and 167 and what to eat
The next edition is on Saturday 24 April 2027, starting in Platja de Muro (Mallorca, Spain) at 6:30. Here you have the route of Mallorca 312, Mallorca 225 and Mallorca 167, its climbs, the usual weather and how much to eat and drink for your target time.
Mallorca 312: route and profile
2025 edition route.
| Climb | Where | Length | Gain | Average grade | Top |
|---|---|---|---|---|---|
| Puig Major | km 47–56 | 8.3 km | +332 m | 4.0 % | 863 m |
| Climb at km 138 | km 138–144 | 5.5 km | +280 m | 5.1 % | 397 m |
Route keys
- Over 310 km and almost 3,900 m: your pace in the first hours through the Tramuntana decides how you finish. Climb below your threshold even if you feel strong.
- The Puig Major (km 55, about 860 m) is the highest point and comes early: don't ride it flat out, there are more than 250 km left.
- With 9–13 hours on the bike, eating matters most: carbs from the first hour and every 20–30 minutes, without waiting to feel hungry.
- After the Tramuntana (until about km 150) the terrain eases: find a group on the flat, where the wind punishes riders on their own.

Mallorca 312: what to eat and drink
How much a typical rider (72 kg) needs depending on their time. From 2–3 hours on, what matters most is eating carbs regularly (every 20–30 minutes) and drinking before you're thirsty.

|---|---|---|---|---|---|
| 9 h | 75 g/h | 570 g | 550 ml/h | 4.9 l | 450 mg/h |

More than 60–90 g of carbs per hour only if you've trained it. Don't try on race day what you haven't tolerated in training.
The organisers provide food and drink stations, but haven't published their kilometres for 2027 yet. When they do, mark them in WinWatts and the plan is redone with your stops.
