The Fred Whitton Challenge is an annual cycle race that uses the Lake District roads. The route climbs six major Lake District passes - Kirkstone, Honister, Newlands, Whinlatter, Hardknott and Wrynose, and is 112 miles long. The race is named in honour of Fred Whitton, a member of the Lakes Road Club who died in 1998. It is now a major event, with warning signs up some time in advance, and for several weeks before the event you'll find large groups of cyclists out practicing.
