Preparing for Mallorca 312 means getting comfortable with a long day on the bike, repeated climbs and eating while you ride. A fast local loop is useful fitness, but it does not tell you how your legs, stomach or contact points will feel several hours later. Your training needs to prepare all three.
The name refers to the longest route, rather than the only distance available. The 2026 edition offered 312km, 226km and 167km options. Check the route, start arrangements and intermediate cut-offs for the edition you have entered before building your plan. Even a shorter option is a substantial ride, especially if you are unused to long climbs.
Start with your current riding, not an arbitrary mileage target
Look at what you have managed consistently over the past month. If that is three rides a week and a two-hour weekend outing, immediately adding several 100km rides is more likely to leave you exhausted than prepared. Extend your usual riding gradually, keeping enough easy time between demanding sessions to recover.
An experienced rider with several months available can organise preparation into a period of consistent endurance riding, a more event-specific block and a short taper. A newcomer may need much longer. There is no single twelve-week schedule that makes every rider ready for 312km, and changing your target distance is a sensible option when training has been interrupted.
Give each ride a purpose
| Session | What it develops | How to use it |
|---|---|---|
| Long endurance ride | Time in the saddle, pacing and fuelling | Build from a duration you already tolerate; practise event equipment and food. |
| Hilly ride or controlled climbing intervals | Sustained effort and gear selection | Keep the effort repeatable rather than racing every climb. |
| Easy ride | Comfortable movement between harder days | Finish feeling that you could have done more. |
| Rest day | Recovery and adaptation | Protect it when work, travel or poor sleep add fatigue. |
For a rider already comfortable with regular training, a week might include an easy midweek ride, a separate hilly session and a longer weekend ride, with an optional short recovery outing. This is an example of how to arrange sessions, not a requirement to train on a fixed number of days. If the long ride leaves you unusually drained, reduce the next session rather than trying to recover lost mileage.
Build the long ride around time and terrain
Distance alone can be misleading. Four hours on flat roads in a group may feel very different from four hours of climbing into a headwind. Track duration, ascent and how well you recover, alongside kilometres. Occasionally riding on consecutive days can help experienced riders practise managing accumulated fatigue, but it should not become an excuse to make every weekend exhausting.
You do not need to complete the full event distance in training. You do need evidence that you can ride for a substantial part of the day, eat regularly and still make sensible decisions near the finish. Use a longer rehearsal to test your clothing, luggage, navigation and stops. Persistent saddle discomfort or numb hands deserve attention before the event.
Prepare for sustained climbing and descending
Short British hills can help develop strength and pacing, but Mallorca also asks you to settle into longer efforts. On a suitable hill or indoor trainer, practise riding at a controlled intensity that you can repeat without a large drop in output. Choose gearing that lets you keep pedalling comfortably as fatigue builds.
Our Sa Calobra cycling guide gives a useful picture of Mallorca’s climbing terrain for training trips, although you should not assume that climb is part of your event route. For riding closer to home, these tips on handling short, steep climbs can help you manage changes in gradient.
Descending is part of preparation too. Practise looking through corners, braking before the turn and leaving room for other riders. If you use the drops, make sure your brake levers remain easy to reach; our guide to when to ride in the drops explains the control benefits and fit considerations.
Practise eating before event week
Long rides are the place to find out which foods and drinks you tolerate. A carbohydrate intake of around 30–60g per hour is a useful starting range for sustained endurance riding; some trained riders work towards 60–90g per hour for very long events. Higher intakes need practice rather than a sudden change on the start line.
Count what you actually consume. A bottle, a gel and a bar can add up quickly, while taking food with you is not the same as eating it. Begin fuelling early and divide intake across the hour. Plan drinking around conditions and your own needs, without forcing a fixed volume regardless of temperature or thirst.
Use the final weeks to arrive rested
Complete your demanding rehearsal rides with enough time to recover. In the final week or two, reduce the overall training load while keeping some familiar, short riding in the schedule. Last-minute mileage cannot replace months of preparation and can leave you starting with tired legs.
Check tyres, brakes, drivetrain and cleats before travelling, then leave time for a short test ride after reassembly. Avoid introducing a new saddle, unfamiliar shoes or an untested fuelling strategy immediately before the event.
Pace for the whole day

The opening kilometres can make an easy effort feel slow when everyone around you is excited. Resist following a group that requires repeated surges. Ride the early climbs conservatively, use feed stops deliberately and keep enough attention for descending safely.
Intermediate cut-offs matter as much as the finish deadline. Download the current route and know where shorter-distance decisions are made. Your most useful training feedback is whether you can finish a long ride eating, thinking and pedalling well, rather than whether one fresh climb matched someone else’s speed.
