Embrunman race guide: course, swim, bike and run breakdown

Early start (5 AM) on Embrun's water body, Lake Serre-Ponçon. Cold water (17-20°C in August), wetsuit mandatory. Pitch black at start, headlamps on the buoys.

Often the most mentally demanding swim on the circuit: cold, nighttime, at altitude (780 m). Open-water preparation essential.

• Full wetsuit mandatory
• Cold-water training in pool or lake
• Time acclimation (5 AM start)

The Embrunman bike is legendary: Izoard pass (2,360 m), climb to Granon, descent to Briançon, then return via rolling roads. 5,000 m of elevation make it one of the hardest bikes in world triathlon.

Strategy: ultra-conservative pacing on Izoard. Many athletes ride 6-7h. The run must follow, so finishing this bike in strict Z2 is non-negotiable.

• Specific col work 2-3×/wk in specific phase
• 150-180 km simulations with 3,000+ m elevation
• Compact or triple chainring mandatory (34-32 min)
• Very high-volume fueling (90-100 g/h over 7-8h)

Loop marathon around Embrun, with constant surges and a few steep hills. Not flat at all. Often run in high heat as mountain afternoons are intense.

Strategy: run by HR, not pace. Accept walking steep hills. Strict hydration and fueling.

• Regular hilly running test in prep
• Heat acclimation (possible heatwave mid-August)
• Planned walk-run strategy on hills

Strategy: finishing first

Embrunman isn't raced for the chrono: it's raced to finish. DNF rate is among the highest on the circuit, especially in heat.

First-timer goal: finish within the cutoff (15h). Ultra-conservative pacing on everything, impeccable fueling, steel mindset over 12-14h.

Logistics: high Alps

Arrive 5-7 days before to acclimate to altitude (Embrun = 780 m) and test gear on cols. Town lodging or camping, very limited spots.

Mid-August weather: 28-35°C in valleys, 15-20°C on cols. Very adaptable bike kit, multiple layers.
