Clock Change Challenge 2026

The Clock Change Challenge is a road race in Calne, Wiltshire, starting at Calne Community Campus and the leisure centre on White Horse Way. It takes place around the UK clock change and features accurately measured 10km and 5km races, alongside a 1.5km Fun Run. The 10km is part of the Wiltshire Road Race League, attracting club runners and local participants seeking a timed autumn race. The event is in its 17th year, a consistent fixture for Wiltshire runners. The 10km is open to those aged 15 and up, the 5km to those aged 11 and up, and the Fun Run offers younger children a shorter route around a playing field. 10km and 5km participants receive custom event medals, Fun Run finishers get their own medals, and past events have sold out before race day. Course records are 30:27 and 36:42 for the 10km, and 15:10 and 18:05 for the 5km.
