The Lowdown
Guildford 10K is a closed-road, chip-timed 10K through the historic center of Guildford, Surrey, organized by Run Through in partnership with Guildford Borough Council. The out-and-back course starts and finishes on the cobbled High Street, running along fully closed roads out toward Clandon on the Epsom Road before returning to the finish beneath the town's landmark Guildhall clock. The same morning also features a 5K and a 2K Junior Race over the same closed-road network, and the event supports the Guildford Town Centre Chaplaincy as its charity partner. UKA-measured and professionally chip-timed, the course is largely flat with a few gentle rolls, making it a popular fast target for local and regional runners as well as a scenic introduction to racing through one of Surrey's best-known market towns.
