Intervals.icu

What the Maures throws at you

Typical sessions

100.6km off-road with 3,680m of climbing, far more fatiguing than the same hours on road.

A 4 out of 5 technical rating: rocky descents and singletrack that demand real bike handling.

A sustained climb-then-descend rhythm, roughly 37m of climbing per kilometre, with no long flat to hide on.

Mediterranean October heat, often 18 to 26C over a five to nine hour day.

What your weeks look like

Typical sessions

3x12min at 95 to 100% FTP on a real climb, building sustained MTB climbing power.

Long Z2 MTB rides progressing from 2hr to a 5 to 6hr peak on rolling, hilly trails.

Back-to-back weekends: 4hr Saturday plus 3hr Sunday on technical terrain for cumulative fatigue.

Skills under fatigue, 30min on technical trail after a hard ride, plus heat sessions in the final weeks.
