RUNFORESTRUN Indian Summer Ultra 2026

The RUNFORESTRUN Indian Summer Ultra is an ultra trail race held in Gasselte, Netherlands, featuring routes within Drentsche Aa National Park. Participants can select from 50 km, 75 km, or 100 km distances, positioning the event within long-distance trail running, distinct from standard road races. The course incorporates two specific areas of the national park: the Balloërveld and the Gasterse Duinen. While solo entries are available, the longer distances can be completed by duos or relay teams of up to five individuals. This option allows runners to experience the RUNFORESTRUN atmosphere without committing to the entire distance solo. The race is organized by adam&events, the same group behind other RUNFORESTRUN trail events.
