Frequently asked questions
Is the tOur du Lac en 1 jour Solo GPX available?
Yes. The track and its profile can be viewed here, and the file is available as a free download from this page.
Do these details replace the organiser's instructions?
No. This page makes sources easier to consult and separates published data from GPX calculations. Check the latest official instructions before the start.
Start on Saturday 30 May 2026: first wave at 01:25, last solo wave at 03:20, Paris time. Use your own assigned wave for personal planning.
Light aid stations: km 17.3, 28.1 and 66.9. Water: km 36.9. Main aid bases: Doussard km 46.6 and Semnoz km 85.5. Station menus are documented; quantities and stocks are not guaranteed.

Personal assistance only in the authorized areas at Doussard and Semnoz. Supporters cannot enter the aid-station tents. Be self-sufficient between stations.

Equipment: official table published in September 2025 with no printed edition year. Cold-weather and heatwave variants are conditional; their actual activation in 2026 was not found. The jacket is checked for solo runners with a weather-related note requiring confirmation.
MaXi-Village 2026: parking des Marquisats, 54 rue des Marquisats in Annecy. The guide places the railway station about 25 minutes away on foot; no shuttle serves the overnight tOur du lac start.

Checks before the start
Check your wave and plan the walk to the overnight start.
Plan self-sufficiency between stations; restrict crew support to the two bases.
Check the latest documents for your edition, pole restrictions and activated weather kit.
Allow a margin before each cutoff and retain Sunday 31 May for times after midnight.
Differences and information still uncertain
These items are shown explicitly so an approximation is never presented as official data.
Strictly a 2026 dossier. The race page, currently linked guide and online regulations have moved to 2027; their new provisions are not imported as 2026 rules.
The 2026 table gives 100 km, 5,782 m ascent and 5,780 m descent; the organizer’s track gives 100 km, 5,446 m ascent and 5,444 m descent. Marker totals remain those of the table; GPX metrics are kept separately.
Table distances are indicative. Intermediate marker coordinates and elevations are absent from this document, so no geographic precision is invented. Generic Sommet, Col and Forêt names are retained.
The window from the last 03:20 start to the next-day 04:20 finish is 25 hours. Without archived 2026 regulations confirming a global limit, no single maximum duration is inferred; published cutoffs are preserved.
2026 drop bag, exact medical stations, toilets per station, jacket waterproof rating, complete penalties, bib collection times and weather-kit activation: not confirmed by the 2026 documents found.
The 30 May 2026 date is corroborated by the MyTrails programme and official transport guide; 01:25 denotes the first wave, not every runner’s personal start.
