PHOENIX - Winter Runderland 2026

PHOENIX Winter Runderland is a winter running event on the River Thames, structured around laps rather than a single fixed distance. Participants can select from 5km to 10km, half marathon, marathon, or ultra distances by completing 5.3km out-and-back laps within a 7-hour timeframe. The start is flexible, with runners able to begin within a 1-hour window, and special start times can often be arranged based on the planned distance. The course follows the Thames out and back, allowing a straightforward format: complete one lap for a finish, or continue laps to increase distance. The event welcomes all abilities, from those targeting a 5km lap to runners utilizing the full time limit for an ultra. Each participant receives a custom finisher's medal; this edition features the event's Snow Globe medal design with a new color palette.
