312 km·5,050 m climbing·10-14 hours·April

THE FOCUS RIGHT NOW

BUILD THE ENGINE.

Twelve weeks out, you're still building the base — but specific structure is starting to appear. Tempo work enters the picture one day a week. Long rides get longer. This is where the event-specific fitness starts to take shape without compromising your aerobic foundation.

THIS WEEK'S ANCHOR SESSION

TEMPO SANDWICH

2x20min at tempo (76-88% FTP) inside a 2-hour Z2 ride. Steady, controlled, not a time trial. This is your first taste of extended race-pace efforts.

DON'T DO THIS

Don't start threshold intervals yet. The build phase will come. If you jump intensity too early you'll peak 6 weeks before race day and arrive flat.

EVENT INTEL

WHAT THE MALLORCA 312 ACTUALLY DEMANDS

The Mallorca 312 is spring's most talked-about sportive — 312km around Mallorca with 5,000m+ of climbing, including Sa Calobra, the iconic hairpin-laced descent-then-climb that defines the day. Runs in late April. Open-road format, closed to traffic in parts.

KEY CHARACTERISTICS

  • ✓Sa Calobra — 10km descent into the sea then 10km climb back out, 7% average
  • ✓Coll de Sóller tunnel + classic north-coast climbs stacked early
  • ✓312km distance means fuelling strategy determines who finishes
  • ✓Three distance options: 312km, 225km, 167km — pick realistically
  • ✓Weather shift from cold morning climbs to afternoon Mediterranean heat

COMMON MISTAKES

  • ✕Choosing the 312 because you've done other long sportives — Mallorca's combination of distance + heat is different
  • ✕Underfuelling the first 80km because the climbing starts easy
  • ✕Forgetting the Sa Calobra climb is a 9% average, not a gentle return — many riders bonk here

PACING

The 312 is a fueling problem more than a fitness one. Pace the opening 100km at 60-65% FTP maximum. Ride the middle 100km conservatively with strict carb/fluid discipline. The last 100km is where preparation shows — those who fuelled correctly can even push. The Sa Calobra climb is at 220km — arrive with reserves, not red-lined.

FUELLING

10+ hours means 80g carbs/hour minimum, 100g if gut-trained. 500-750ml fluid/hour once the heat kicks in. Food at every aid station on the route — don't skip any. Electrolytes become dominant after hour 6. A 'second breakfast' at the Pollença aid stop (km 80) is a classic move.

KIT

Long-finger gloves + gilet for the first two hours (cold on the climbs pre-dawn). 34x30 minimum, 34x32 recommended for Sa Calobra late in the day. Extra bottle cages or a frame bag for the long desert-like middle section.

FAQ

COMMON QUESTIONS AT 12 WEEKS OUT

Is 12 weeks enough to train for the Mallorca 312?+

Yes, 12 weeks is a strong window. That's enough time for a full base phase, build, peak, and taper — the classical periodisation structure. 5,050m of climbing over 312km is built with sustained Z2 volume (base) + threshold work (build) in that order.

What's the hardest part of the Mallorca 312?+

Sa Calobra — 10km descent into the sea then 10km climb back out, 7% average. choosing the 312 because you've done other long sportives — Mallorca's combination of distance + heat is different — so pacing discipline is the single biggest lever most amateurs miss. The 312 is a fueling problem more than a fitness one.

How many hours a week should I train at 12 weeks out from the Mallorca 312?+

Aim for 8-12 hours/week if you're targeting a strong finish. The long weekend ride is the anchor (3-4 hours at build intensities) plus 3-4 structured weekday sessions. Volume matters more than intensity at this phase.

Do I need a coach to train for the Mallorca 312?+

You don't need a coach to finish. You do need structure. If you're new to sportives, have a target finish time, have a plateau you can't break, or have a history of peaking wrong, a coached plan pays for itself. Inside Not Done Yet the plan is built backwards from your event date — base, build, peak, taper timed to the week the Mallorca 312 runs. 7-day free trial, $195/mo.

What gearing should I run for the Mallorca 312?+

Long-finger gloves + gilet for the first two hours (cold on the climbs pre-dawn). 34x30 minimum, 34x32 recommended for Sa Calobra late in the day. Extra bottle cages or a frame bag for the long desert-like middle section.
