Gloucester Half Marathon & 10k Presented by TREK March 2027

Join us for the Gloucester Half Marathon & 10k Presented by TREK on Sunday 21st March 2027!

Take on a memorable race day in Gloucester with a route that blends city-centre atmosphere, historic landmarks, and scenic waterside running. Starting and finishing at Gloucester Park, this event gives runners the chance to race through pedestrianised city centre streets, pass around the iconic Gloucester Cathedral, and head out on a closed road circuit through Gloucester and Quedgeley before joining the Gloucester & Sharpness Canal Path.

Whether you are stepping up to the Half Marathon or taking on the 10K, this event offers a varied and rewarding course with strong local support and plenty to enjoy along the way. From the energy of the city streets to the calmer stretches beside the canal, every mile brings something different, making this a standout spring event for runners of all levels.
