The Kilomathon series was launched in 2010 with over 10,000 runners making history in Scotland and England. There are three Kilomathon distances to choose from. The 13.1k is an excellent distance for those looking to step-up from a 10k, or looking for a bridging gap between a 10k & a half marathon. The 6.55k is an ideal step-up from a 5k, or as a stepping stone to the 10k distance. The 2.62k junior race is a fun race for kids.
