Overview

Held in Longeville-lès-Metz, France, this road race featured an exceptionally flat profile with just 10 meters of total elevation gain across 50 kilometers, working out to 0.2 meters of climb per kilometer. The circuit utilized paved walkways and stabilized paths on an entirely pedestrian route, beginning with 1 loop of 2 kilometers followed by 12 loops of 4 kilometers that runners shared alongside a 100-kilometer event.

An 8-hour time limit demanded a minimum pace of 9.6 minutes per kilometer. That cut-off was tighter than 84% of 50k races and more generous than 16%, keeping pressure on pacing despite the lack of hills. The event drew a compact field—smaller than 62% of 50k peers and bigger than 37%—concluding its 2025 edition with 24 finishers.
