1500 km·35,000 m climbing·6-9 days·October

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 TRANS PYRENEES ACTUALLY DEMANDS

Trans Pyrenees is one of the hardest self-supported ultras in Europe — 1,500km from Biarritz to Barcelona (or reverse) across every major pass in the Pyrenees, with 35,000m of climbing. 6-9 day finishes. October weather unpredictable.

KEY CHARACTERISTICS

  • ✓35,000m climbing — that's 4× Everest across the event
  • ✓Every HC and Cat 1 Pyrenean pass featured — Tourmalet, Aubisque, Aspin, Peyresourde, Porto
  • ✓October weather: snow on passes, freezing rain, wind
  • ✓Self-supported — you carry, you sleep where you can
  • ✓Mandatory tracker, daily check-in times

COMMON MISTAKES

  • ✕Treating it like Badlands (Mediterranean) — the Pyrenees are colder, wetter, mountainous
  • ✕Underspecing kit — October above 1,800m needs winter gear
  • ✕Sleep deprivation affecting descending safety on day 4+

PACING

Trans Pyrenees is a climbing-dominated ultra. Pace on the climbs — not the flats. Target sub-threshold on every pass, regardless of time pressure. Sleep 5-7 hours/day for sustainable progress. Check weather nightly and pick tomorrow's start time accordingly.

FUELLING

No aid stations. Resupply at open shops, cafés, petrol stations. 80-100g carbs/hour on the bike, with real food stops at cafés every 4-5 hours. Hot drinks at altitude pass points matter more than people expect. Carry extra gels for nighttime emergencies.

KIT

Full bikepacking kit. Dynamo hub for lights + devices. 32-35mm tyres with reinforcement. Waterproof jacket, waterproof gloves, waterproof socks. Bivvy + sleeping bag rated to 0°C. Emergency mylar blanket. Spare battery pack.

FAQ

COMMON QUESTIONS AT 8 WEEKS OUT

Is 8 weeks enough to train for the Trans Pyrenees?+

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 Trans Pyrenees?+

35,000m climbing — that's 4× Everest across the event. treating it like Badlands (Mediterranean) — the Pyrenees are colder, wetter, mountainous — so pacing discipline is the single biggest lever most amateurs miss. Trans Pyrenees is a climbing-dominated ultra.

How many hours a week should I train at 8 weeks out from the Trans Pyrenees?+

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 Trans Pyrenees?+

Inside Not Done Yet the plan is built backwards from your event date — base, build, peak, taper timed to the week the Trans Pyrenees runs. 7-day free trial, $195/mo.
