Lourdes, France · July · Independent

Why people love it

Finish at the Tourmalet summit (about 2,115 m (6,940 ft) / 6,940 ft) after Aspin and Pic du Midi.
Brand-new extreme event pitched as a stepping stone toward Norseman.
Lourdes has abundant hotels and a local airport.
About 4,800 m (15,700 ft) of bike climbing on Tour de France roads.

Inaugural 2026 edition, so the track record is thin.
Storms and hail halved the 2026 run and caused many dropouts.
03:00 dark mass swim with heavy contact reported.
Only one press review found; official course and cutoff details were not readable.
The finish is about 2,100 m (6,900 ft) up, so expect cold at the summit after a warm valley day.

L'Avenir (Belgium)Raced 2026 · article · Mixed
Two Belgian amateurs recount the inaugural edition: about 350 registered, 237 starters, 211 finishers. Swim in the dark was rough with contact; bike with ~4,800 m (15,700 ft) of climbing went through thunderstorms and hail near the Aspin; the run was cut roughly in half because of the weather. The paper notes many dropouts, and the second athlete finished exhausted in 189th.
