HAUTE ROUTE ALPS16 WEEKS OUT

Aerobic foundation. High volume, low intensity. Don't skip this. Built around the 920km / 21,000m profile of the Haute Route Alps in France / Italy / Switzerland.

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 HAUTE ROUTE ALPS ACTUALLY DEMANDS

Seven days of timed Alpine stage racing — 920km from Nice to Geneva over 21,000m of climbing, including Bonette, Galibier, Iseran, Colombière, and Joux Plane. Each stage is timed against the field; the GC after stage 7 is what people remember. ASO-quality logistics, transfer trucks, mass starts, and a peloton that races every day.

KEY CHARACTERISTICS

  • Seven daily stages averaging 130km + 3,000m climbing — the cumulative load is the event
  • Multiple HC climbs each day — Bonette (2,802m), Galibier (2,642m), Iseran (2,764m), Joux Plane (1,691m)
  • Timed format with daily GC — riders race, not just finish
  • Altitude exposure 2,000-2,800m on most stages — power drops 8-15% at the top
  • Recovery between stages is the real workload — massage, nutrition, sleep, repeat

COMMON MISTAKES

  • Riding day 1 like a sportive PR attempt and arriving at day 4 cracked
  • Under-fuelling the recovery window — calorie debt compounds across stages
  • No back-to-back long-ride training — sportive fitness does not transfer to multi-day

PACING

Treat each stage as a 70-80% effort, not a 100% effort. Day 1 power should be the slowest you can hold for 5-6 hours, not the fastest. The leaderboard rewards consistency — riders who finish day 4 at 90% of day-1 power move up the GC; riders who blow up on day 2 ride defence for the rest of the week. Pace climbs on rigid wattage ceilings, not on the wheel in front of you.

FUELLING

On-bike: 80-100g carbs/hour for 5-7 hours daily, with feed-zone discipline. Off-bike: this is where the event is won. 1.2-1.5g protein per kg body weight per day, refined carb intake 8-10g/kg/day during the week, and a recovery shake within 30 minutes of crossing every finish line. Sleep is fuel — riders who skip the post-stage protocol crack on day 4 regardless of fitness.

KIT

Climbing bike with 34x32 minimum, 34x34 if you have it. Two complete kit setups so one is always laundered. Light insulated layer for high-pass descents (Bonette, Iseran tops can be sub-5°C even in August). Recovery kit: foam roller, compression, recovery shake powder, electrolyte tabs. Massage is included most years — book early, every day.

FAQ

COMMON QUESTIONS AT 16 WEEKS OUT

Is 16 weeks enough to train for the Haute Route Alps?+

Yes, 16 weeks is a strong window. That's enough time for a full base phase, build, peak, and taper — the classical periodisation structure. 21,000m of climbing over 920km is built with sustained Z2 volume (base) + threshold work (build) in that order.

What's the hardest part of the Haute Route Alps?+

Seven daily stages averaging 130km + 3,000m climbing — the cumulative load is the event. riding day 1 like a sportive PR attempt and arriving at day 4 cracked — so pacing discipline is the single biggest lever most amateurs miss. Treat each stage as a 70-80% effort, not a 100% effort.

How many hours a week should I train at 16 weeks out from the Haute Route Alps?+

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 Haute Route Alps?+

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 Haute Route Alps runs. 7-day free trial, $195/mo.

What gearing should I run for the Haute Route Alps?+

Climbing bike with 34x32 minimum, 34x34 if you have it. Two complete kit setups so one is always laundered. Light insulated layer for high-pass descents (Bonette, Iseran tops can be sub-5°C even in August). Recovery kit: foam roller, compression, recovery shake powder, electrolyte tabs. Massage is included most years — book early, every day.
