The Challenge Sandefjord Middle Distance courses will be new in 2025. The swim will take place at Granholmen Camping, five km from the city center. It will be a rolling start with five second intervals. There is 100 meters to the first buoy, where you turn right before swimming towards a couple of small rocks. There you round and swim back, find the way to the transition and get ready for the bike section.

You will cycle into the center of Sandefjord, which is five km away, where you round by the Badeparken before setting off towards a beautiful landscape. It is a rolling course, with curves and long flat stretches. The bike section runs on roads that are open to regular traffic. We expect little traffic early Sunday. There are bike guards at all intersections and the police ride before the first athlete. After two laps you will go to the transition in the Badeparken. You will have two aid stations on each lap.

Out on the run you will get to know the center of Sandefjord. A small climb up towards Brydedammen and the aid station, before returning to the city center and traditional buildings from the time Sandefjord was a famous shipping port.

The finish line is in Badeparken, where you will find your participant bags and the after-food area.
