Strict cutoff times: CP4 at 13.5km (2h 15min from start) and CP6 at 17.5km (3h 15min from start). Aid stations at 8.5km, 13.5km, and 17.5km. Route features highly technical rocky terrain; two exposed ridge sections near the summit require careful footing — falls not forgiven. Recommended for experienced mountain runners only.

Runners registering by July 31 receive a ceramic medal with their name engraved on the back. Payment by card only.
