Overview

Held in Monschau, Germany, the Belgenbach-Ultra-Trail Monschau BUT 46 covers a 46-kilometer route organised by TV Konzen 1922 e.V. with an entry fee of 42 Euro.

The course packs 1440 meters of elevation gain into its distance, averaging 31.3 meters of climb per kilometer through the Eifel terrain. That steady profile meets a strict 7-hour time limit. With a required cutoff pace of 9.1 minutes per kilometer, the race is tighter than 90% of 50k cut-offs and more generous than only 10% across 1047 peers, leaving little buffer for prolonged slowdowns on the climbs.
