About The 2026 ENDURrun Prelim
The 2026 ENDURrun Prelim is a unique six-day, six-stage running event held in Waterloo, Ontario, and its surrounding communities. Designed as a preparatory challenge for the more demanding ENDURrun events later in the year, the Prelim offers runners a comprehensive test of endurance, speed, and versatility. Participants tackle a variety of race formats, including road, cross-country, trail, and track, over a total distance of 60 kilometers.
This event is renowned for its supportive community atmosphere, well-organized stages, and diverse terrain. Each stage is carefully crafted to challenge different aspects of a runner’s skill set, from technical trail running to fast-paced track racing. The Prelim is ideal for athletes seeking to experience the spirit of multi-day racing, build confidence, and prepare for longer endurance events. With leader bibs, finisher medals, and awards for top performers, the ENDURrun Prelim is both a competitive and celebratory experience.
