CLEE Hill will be staging a mountain-bike and orienteering event this Sunday.
The second round of the Midland Trailquests Autumn Series takes place at Cleeton St Mary.
Competitors will be given a map with 30 control points of various values marked on it and have three hours to choose the best ones to visit and the best route.
Organiser Graham Phillips said: "Mountain bike orienteering is an exciting sport for all ages and abilities.
“There will be plenty of control points near the event centre for beginners, while more experienced riders can try to cover all four corners of the map."
Spot prizes are provided by Clee Cycles of Ditton Priors. Proceeds will go to Midland Air Ambulance.
Entry is £10 on line in advance or £12 on the day and all entrants must be members of Midland Trailquests Membership is free and to join, go to: http://www.midlandtrailquests.co.uk
