Colworth Str1ders

Colworth Marathon Challenge

The Marathon Challenge is a suite of three races which take place over three consecutive days. The races consist of a 5 mile run, an 8.1 mile trail race, and a half marathon; all of which adds up to a full marathon distance. Races may be entered in any combination, i.e. you may enter one, two or all three. Details of each race are below.

The events will be run under ARC race permits, and therefore we need to charge a £2 non-affiliated fee for non-affiliated runners. If you are a member of an affiliated club, such as Colworth Str1ders, you do not need to pay. The charge only needs paying once regardless of the number of races entered.

The dates for the 2023 races will be 23/24/25 June.

The results of the previous races can be found here.
