The page announces a 45h30 maximum, but the closing time shown in Chamonix is 30 August at 17:30. The wave rule exists; the time of the last wave is not confirmed. Do not recalculate or modify the cutoffs to hide this discrepancy. The table gives 173.6 km and 9,700 m D+. The GPX metadata gives 174 km and 10,000 m D+; the last exported distance is 173.599 km. Trailboard's current calculation gives 171.508 km, 7,798 m D+ and 8,424 m D−: calculated values kept separate from the organiser's reference. Mountain race crossing France, Italy and Switzerland, with remote sections and weather that can change quickly. The organisation requires personal accident insurance covering search and evacuation in all three countries. Go back to the last beacon if you lose the course marking, stay on the route and use the designated areas for resting. Save the race HQ contact details provided by the organisation and check LiveTrail before the start. No unverified number, weather forecast or rescue time is added to the template.

Differences and information still uncertain

These items are shown explicitly so an approximation is never presented as official data.

  • The announced start is 28 August 2026 at 19:45; the GPX indicates 19:48:12. This exported time is not used as a new official start time.
  • The page states a 45h30 maximum, but the closing time shown at Chamonix is 30 August at 17:30. The wave rule exists; the time of the last wave is not confirmed. Do not recalculate or alter the cutoffs to hide this discrepancy.
  • The table gives 173.6 km and 9,700 m D+. The GPX metadata gives 174 km and 10,000 m D+; the last exported distance is 173.599 km. Trailboard's current calculation gives 171.508 km, 7,798 m D+ and 8,424 m D−: calculated values kept separate from the organiser's reference.
  • The Suunto type simplifies some services: Checrouit and Bertone are exported as Checkpoint, La Flégère as First_aid. The services table confirms their liquid aid station and is authoritative for their category.
  • Detailed menus, Näak references, quantities, stocks, bag drop slots, shuttle times, bib collection and weather activation remain to be confirmed in the edition's instructions.
  • The runner guide page was located, but its embedded viewer did not deliver any usable text. No detail of this guide is presented as verified.
  • This listing documents the 2026 edition. Reusing it to explore the application is neither a registration nor a confirmation of the data for a future edition.
