XLETIX Challenge Mitten in Deutschland is billed as the muddiest race in the series, held at Freizeitpark Mammut near Stadtoldendorf in southern Lower Saxony. Boggy woodland, open fields, water holes and lush meadows make up the course, and many of the obstacles are built directly into the terrain rather than trucked in, so the landscape does most of the work.
FUN covers 6 km with 15 obstacles, ADVENTURE 12 km with 25, and X-TREME 18 km with 35. Camping is available on the event site itself, with camper van pitches about a 15-minute walk away, so the race easily stretches into a full weekend.
