The Colchester 10k started in 2009 as Colchester Charity Races and is organised by volunteers from the Rotary Cub of Colchester Trinity. Representatives from UK Athletics attend on the day to ensure that the race is run according to the official rules with an Official Starter and Adjudicator present.
All other marshals and helpers attend in a voluntary capacity and the proceeds of the race are given to various local and national charities supported by the Rotary Club of Colchester Trinity.
