Sheffield 10K

Sheffield TenTenTen is a multi-terrain trail 10K in Sheffield, with a separate 2.5K fun run for children aged 4 to 14. It is held in October and typically attracts over 1,000 runners, giving it the feel of a local mass event rather than a small club race. The name originates from the first event being held on the tenth day of the tenth month. The main race accommodates a wide range of abilities, from those running their first 10K to athletes who have competed at national level. The children's run adds a family element to the day, with approximately 150 children participating in their shorter race.
