About

The Tro Breizh was a medieval Breton pilgrimage connecting the seven dioceses of Brittany in a sacred loop. The Gravel Tro Breizh revives that spirit as a self-supported ultra bikepacking race of approximately 1,300 km and 19,000 metres of elevation gain circumnavigating the entire Breton region. Starting from Iffendic in Ille-et-Vilaine, just 100 riders have 180 hours to complete the circuit across coastal paths, bocage lanes, gravel tracks and inland forest roads. The 180-hour time limit demands precise day-by-day pace management; at Push Rider, the twelve-week periodised plan includes multi-day pacing work and autonomous nutritional decision-making — pillars that the weekly coach review refines so each stage compounds without compromising the ones that follow.
