The longest circuit of the Trail des 600 Boitheux is the 66 km (66,2 km exactly) and an altitude difference of 2123 m. It allows the finishers to earn 3 ITRA points in preparation for one of the UTMB’s races.
Four quality food supplies in liquid and solid are offered on the circuit (at the km 14, 31, 46, and 63) and another at the finish line. Nevertheless, bring your own food supplies.
According to the COVID-19 rules in force
possible modifications to the supplies
Excellent circuit, really happy that I’ve done this 55 km in 2018. Gauthier.
