Simon Booth (born 10 May 1968[1]) is an English runner who was twice the British fell running champion and who has represented his country at the World Mountain Running Trophy.

However, an early indication of his running ability was his performance at the Cumbria Marathon from Cockermouth in 1982 when he was the first junior to finish at the age of fourteen and beat his father Bill Booth.

[3] He has performed especially well in the longer races and his wins include Wasdale, the Ennerdale Horseshoe, Great Lakes, Duddon Valley, Sedbergh Hills, the Anniversary Waltz, Buttermere Sailbeck, Langdale, the Three Peaks and Skiddaw.

[4] He had a particularly notable sequence of results in the Borrowdale Fell Race which he won twelve times between 1995 and 2010.

[10] In 2015, Booth devised the “No Cure, Always Hope, Ultra Run” from the Newlands Valley based on the 10in10 challenge routes which were set up to raise money for research on multiple sclerosis, a disease with which Booth’s brother Duncan was diagnosed in 2010.
