Lakeland 100

The Montane Lakeland 100, the Ultra Tour of the Lake District, loops the whole of the Lakeland fells from Coniston: south through the Dunnerdale fells, Eskdale, Wasdale, and Buttermere to Keswick, then back by Matterdale, Haweswater, Kentmere, and Ambleside. The course is branded 100 miles and measures about 105, with roughly 6,300 meters of ascent, a 6:00pm Friday start, and a 40-hour limit that still defeats 40 to 50 percent of the field most years.

The Lakeland 50 runs the second half of the same course from Dalemain on Saturday morning, and the two races share the Coniston finish and the biggest race-weekend atmosphere in UK ultrarunning. Live GPS tracking on Open Tracking draws a large following each July.

A clockwise circuit of the Lake District on public bridleways and footpaths, avoiding the popular summits in favor of the valleys and passes between them. Fourteen staffed checkpoints; winners run close to 19 hours and the limit is 40. The 50 starts at Dalemain and covers the final 50 miles of the same route to Coniston.

Entry is a ballot, open for 48 hours in early September for the following July: for 2027 it opened at 9 a.m. on September 1, 2026, and every applicant heard by September 5. A runner can enter the ballot for the 50 or the 100, not both, and the 100 requires qualification. Both races require self-sufficient navigation between checkpoints.
