Lakes in a Day 2025, organized by Durty Events, offers a demanding yet scenic 50-mile ultramarathon through the Lake District on October 11, 2025. Starting in Caldbeck, participants will navigate high fells, including the Helvellyn Ridge, and follow the western shore of Lake Windermere before finishing in Cartmel. The course features 4,000 meters of elevation gain and is designed for experienced trail runners seeking a significant challenge. For the first time, a 23-mile “Half” option from Ambleside to Cartmel is available, providing a less intense but still rewarding experience. Both races include well-stocked aid stations, live GPS tracking, and a finish-line celebration.
