Backyard Sandefjord Ultra

The Backyard Sandefjord Ultra is a gravel running event taking place in Sandefjord, Norway, during October. Participants can choose between a 6.7 km distance, consisting of one short gravel loop, or an 80.4 km ultra-distance. Both distances are run on gravel, providing a distinct off-road character without the technicality of mountain running. Backyard Norge is the organizer, and this event is part of the Backyard Sandefjord series.
