What Everest in a day asks of you

Typical sessions

8,848m of climbing over 242km, with almost no flat to spin the legs out and recover

A ~14 hour cutoff and a low-single-figure finish rate: most Ultrafondo finishers are out 12 to 14 hours

Valley heat of 25 to 32C low down, cold on the high resort roads near 2,000m, and afternoon storm risk

A final climb to Thyon 2000 ridden on comprehensively empty legs, where the day is won or lost

What your weeks look like

Typical sessions

Long Z2 climbing rides of 4 to 6h with 2,500 to 3,500m of climbing, building to 7 to 8h and 5,000m rehearsal days

Sub-threshold climb reps: 3 to 4 x 25 to 40min at 88 to 92% FTP to build the sustained climbing engine

Back-to-back big weekends (6h Saturday, 5h Sunday) to teach the legs cumulative climbing fatigue

Pacing rehearsals ridden strictly at Z2 the whole way, plus heat sessions and post-ride sauna in the final weeks
