Race series
Athlete-first long-course racing.
The Challenge Family was founded in 2002 around Challenge Roth, a race whose history goes back to 1984. Organised as a network of independent event promoters rather than a single corporate series, Challenge races are known for their athlete-first ethos, family-friendly atmosphere and iconic venues across Europe, the Americas, Asia and Oceania. Most events offer both full and half distances; a handful also run middle- and sprint-distance formats. Course descriptions on TriAtlas reflect the flagship (longest) distance for each venue.
