The Seven Sins Run is a winter trail event held at Wenchford Picnic Site, located near Blakeney in the Forest of Dean. The primary course is straightforward in concept yet challenging in execution: seven hills are incorporated into a seven-mile distance.
The event also features the Immortal Sinner, a 14-mile race that involves runners completing the Seven Sins route in reverse followed by the standard route. Additionally, canicross races for participants with dogs are scheduled for one of the days.
