The Bob Graham Round is a fell running challenge in the English Lake District which involves traversing 42 fells (hills) over a 66-mile course with 27,000 feet of elevation gain. It was first done under 24 hours by Bob Graham in June 1932. An related challenge is to summit the most fells in 24 hours.
