The Oldbury 10 mile is the third event in Thornbury Running Club's Race Series. It starts at 10:30 on a Sunday morning in September. This is a measured 10-mile road race for adults, positioned between a 10K and a half marathon, with a two-hour expected run time. Entries are managed through Full on Sport; runners must sign up in advance as there are no entries on the day.
The route follows quiet lanes alongside the River Severn. The club describes it as flat and fast, suitable for runners aiming for speed or stepping up in distance. The race typically counts towards the Avon Road Race Championships. A £100 prize is offered for anyone who breaks the course record: 50:19 for men and 57:09 for women. Finishers get a metal medal, and runners completing all three Thornbury Running Club series races can link their medals to form one larger medal. Guide runners supporting visually impaired runners can enter free using the VI Runners Bristol code.
