Challenge Norway in collaboration with Sandefjord Triatlonklubb are proud to invite the triathlon family to Sandefjord for a two-day triathlon festival. We will host the national championship in long distance, the national championship for youth (13-16), we welcome professional athletes that will fight for glory, and age groupers from all over the globe that just want to have a good experience in this beautiful city. Sign up before somebody else grabs the slot (we have only 600 slots for the middle distance this first year), and be a part of the inaugural Challenge Sandefjord.
