Run as far as you can in six hours
Entries are open for the Daventry Challenge in Northamptonshire on March 12 next year.
The multi-terrain race is a six-hour timed event in which you run or walk as far as you like around a 3.3-mile loop.
Mainly flat with a few small inclines, the surface of the course in Daventry Country Park is mainly crushed stone, although there are sections through a meadow and woodland.
Environmentally friendly, the event is cupless and competitors can fill their own bottles or hydration packs at the water stations on their way around.
