St jo trail d 2 rivieres is a trail race in Saint Joseph, France, with a 65 km option that climbs 2,800 metres of positive elevation. The listed start time for that long race is 5:00 AM, so runners begin before daylight and face a long day on hilly ground.
Registration is listed through Miles Republic, with bib prices shown at 70 EUR for one 65 km entry and 35 EUR for another 65 km option. The available facts point to a stripped-down long trail event: serious distance, serious climbing, an early start, and only the basic entry details published.
