THE FOCUS RIGHT NOW

BUILD THE ENGINE.

Sixteen weeks out, your job is volume. Forget intervals. Forget Strava. Build the aerobic engine that every later phase sits on top of. 80% of your time should be in Zone 2 — conversational pace, nose-breathing territory. If your base phase feels easy, you're doing it right.

THIS WEEK'S ANCHOR SESSION

THE LONG Z2 RIDE

One 3-4 hour steady Zone 2 ride per week. Flat to rolling route. Cadence 85-95rpm. Heart rate below first ventilatory threshold the whole way. This is where your mitochondrial density grows.

THE WEEK

A TYPICAL WEEK, 16 WEEKS OUT

Monday

REST OR 45MIN Z1

Recovery day — coffee spin only if you want to.

Tuesday

90MIN Z2 ENDURANCE

Steady, controlled, aerobic.

Wednesday

1H STRENGTH + 30MIN EASY SPIN

Squats, deadlifts, core. Builds what the bike can't.

Thursday

90MIN Z2 WITH 3X5MIN TEMPO

Intro to structured effort — don't race it.

Friday

REST

Genuine rest. The adaptations happen now.

Saturday

3-4H LONG Z2 RIDE

Anchor session. Fueled from minute 30.

Sunday

90MIN GROUP RIDE OR SOLO Z2

Social pace. No heroes allowed.

DON'T DO THIS

The #1 base-phase mistake: riding too hard on easy days. If you arrive at Saturday already tired, you'll never build the aerobic depth you need. Discipline the volume, discipline the intensity.

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 16 WEEKS OUT

Is 16 weeks enough to train for the Mallorca 312?+

Yes, 16 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 16 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 late base 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.
