Eleven hardy runners from the Gade Valley Harriers tackled the formidable Winter Wolf Run in Leicestershire at the weekend.
The course is an unique combination of three kinds of off-road running; mud runs, trail runs and obstacle runs.
The only Wild Run in the UK, it is a taxing 10k trail across raw natural terrain, including open ground, woodland, lakes and thick mud.
It had the Harriers tackling a series of tough obstacles – both man-made and natural – designed to test mental and physical strength, skill and stamina.
Despite the treacherous conditions, the Harriers – who ran under the team name Kitty Kats – stuck together in their pack and all crossed the finish line in one piece.
