Lakes In A Day Ultra & 23M Trail Run

View all races for Oct 2026

Lakes in a Day is a point to point mountain ultra crossing the Lake District from Caldbeck in the north to Cartmel in the south. The 50 mile route climbs around 4,000m as it travels through some of the region's most dramatic mountain landscapes, including Blencathra, the Helvellyn Ridge and the western shoreline of Lake Windermere.

The full route is a demanding mountain challenge, with rough fell terrain, river crossings, sustained climbing and long periods on exposed high ground. Much of the course is not waymarked, so runners need suitable mountain experience and navigation skills rather than relying solely on GPS. After the high mountain sections, the route continues through Ambleside and alongside Windermere before heading towards the finish at Cartmel.

A 23 mile trail race provides a shorter alternative, travelling from Ambleside to Cartmel via the western shore of Lake Windermere, Claife Heights and Bigland Tarn. This route avoids the highest mountains and is fully waymarked, while still providing a hilly Lake District trail challenge and sharing the closing stages of the full Lakes in a Day route.
