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.
The lake circuit is advertised as 100–103 km with 5,300–5,500 m ascent, clockwise via Veyrier then Semnoz. Table distances are indicative.
Collect the bib the previous day at MaXi-Village with supporting documents and ID. Adults must book a slot from 23 April to 21 May; no race-day collection.
Crew support only at Doussard and Semnoz aid bases. Stow poles in the first section; two 500 m stretches near Col de Bornette prohibit poles.

Exact medical stations, food stocks and intermediate coordinates are unconfirmed. No service absent from the sources is invented.
