THE FOCUS RIGHT NOW

BUILD THE INTENSITY.

Eight weeks out, the build phase kicks in. One threshold session, one VO2 max session, and the long ride all in a week. Volume stays high, but now intensity layers on top. This is where your FTP should start climbing — if it doesn't, distribution is wrong, not effort.

THIS WEEK'S ANCHOR SESSION

2X20MIN THRESHOLD

Warm up 15min. 2x20min at 91-105% FTP with 5min recovery between. Cool down. Hit the target power both reps — if you fade the second, you started too hard. This is your bread-and-butter threshold session.

THE WEEK

A TYPICAL WEEK, 8 WEEKS OUT

Monday

REST

Recovery is a session — treat it like one.

Tuesday

THRESHOLD INTERVALS (2X20MIN)

Your key quality session of the week.

Wednesday

90MIN Z2 + STRENGTH

Reduced gym volume — maintenance only.

Thursday

VO2 MAX (4X4MIN @ 106-120% FTP)

Push the ceiling. Rep 4 should be the hardest.

Friday

REST OR 45MIN RECOVERY

Legs up.

Saturday

4-6H LONG RIDE WITH 3X15MIN AT EVENT PACE

Specificity starts here.

Sunday

2H Z2

Active recovery.

DON'T DO THIS

Do not stack threshold and VO2 max back-to-back. 48 hours minimum between quality sessions. Stacking kills the adaptation and makes you fragile.

EVENT INTEL

WHAT THE MARMOTTE ACTUALLY DEMANDS

La Marmotte is the original European mass-participation Alpine event — 174km from Bourg d'Oisans over the Glandon, Télégraphe, Galibier and finishing on Alpe d'Huez. 5,000m of climbing in one day, four giant cols, and a culture that treats it as the amateur Tour de France stage.

KEY CHARACTERISTICS

  • Four legendary cols: Glandon, Télégraphe, Galibier, Alpe d'Huez
  • Galibier summit at 2,642m — altitude bites the upper third
  • Alpe d'Huez summit finish after 150km already in the legs
  • July heat in the Maurienne valley regularly hits 35°C+
  • Gold/silver/bronze finishing standards — riders chase the time bands

COMMON MISTAKES

  • Racing the Glandon in the opening cool air and arriving at the Galibier hollow
  • Underfuelling because the climbs feel manageable in the first half
  • Choosing 11-28 gearing and meeting Alpe d'Huez at 50rpm

PACING

Pace La Marmotte from the Alpe backwards. Glandon at 70-75% FTP, Télégraphe-Galibier as a paired sub-threshold effort, Alpe d'Huez ridden on a wattage ceiling regardless of heat or crowd. The valley between Galibier descent and the Alpe is the day's hidden test — tailwind, heat, fatigue. Eat through it, do not hammer.

FUELLING

8-10+ hours demands 90-110g carbs/hour minimum, and the gut has to be trained for it. Force-drink on a timer once the valley heat lands — Maurienne in July is brutal. Refill bottles at every feed; the climb to Alpe d'Huez is the worst place on earth to run dry.

KIT

34x32 minimum, 34x34 if you have it. Gilet and arm warmers stashed for the Galibier descent (genuinely cold even on 35°C days). Clear lenses for the descents. Sunscreen reapplied at every feed — Alpine UV plus an 8-hour day is a sunburn waiting to happen.

FAQ

COMMON QUESTIONS AT 8 WEEKS OUT

Is 8 weeks enough to train for the La Marmotte Granfondo Alpes?+

Yes, if you already have a reasonable aerobic base. 8 weeks out means peak and taper — we can sharpen and refine, but we can't build new aerobic fitness from scratch. If you're starting from zero now, aim for finishing rather than personal bests.

What's the hardest part of the La Marmotte Granfondo Alpes?+

Four legendary cols: Glandon, Télégraphe, Galibier, Alpe d'Huez. racing the Glandon in the opening cool air and arriving at the Galibier hollow — so pacing discipline is the single biggest lever most amateurs miss. Pace La Marmotte from the Alpe backwards.

How many hours a week should I train at 8 weeks out from the La Marmotte Granfondo Alpes?+

Reduce to 8-10 hours with rising intensity quality. This is the peak phase — fewer, sharper sessions. Long weekend ride stays but drops slightly (3-4 hours with event-specific work). Weekday sessions are shorter and more intense.

Do I need a coach to train for the La Marmotte Granfondo Alpes?+

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 the Not Done Yet coaching community the plan is built backwards from your event date — base, build, peak, taper timed to the week the La Marmotte Granfondo Alpes runs. 7-day free trial, $195/mo.

What gearing should I run for the La Marmotte Granfondo Alpes?+

34x32 minimum, 34x34 if you have it. Gilet and arm warmers stashed for the Galibier descent (genuinely cold even on 35°C days). Clear lenses for the descents. Sunscreen reapplied at every feed — Alpine UV plus an 8-hour day is a sunburn waiting to happen.
