Overview

The Plesse UltraRun (PUR) - 72 km takes place in Bovenden, Germany, offering an uncommonly gentle profile for trail runners. With just 5.6 meters of climb per kilometer and 280 meters of elevation gain across the 50-kilometer route, the terrain presents minimal sustained climbing compared to standard trail outings. The course incorporates forest paths, meadows, gravel, and asphalt, passing Burg Plesse and views over the Leinetal.

Participants face an 11-hour time limit, translating to an accessible cut-off pace of 13.2 minutes per kilometer. That timing is more generous than 64% of 50k cut-offs and tighter than 36%, granting substantial breathing room across the distance.

With 25 finishers in 2025, the event operates on a modest scale—bigger than 38% of 50k fields but smaller than 61%. Entry fees sit at 30/35 EUR for the November race organized by Bovender SV.
