The Bob Graham Round is a fell running (hill running) challenge in the English Lake District. It is named after Bob Graham (1889–1966), a Keswick guest-house owner, who in June 1932 broke the Lakeland Fell record by traversing 42 fells within a 24-hour period. Traversing the 42 fells, starting and finishing at Keswick Moot Hall, involves 66 miles (106 km) with 26,900 feet (8,200 m) of ascent. The Round was first repeated, in a better time, in 1960 by Alan Heaton.
