Because Tarrywile has that rather lovely hill on the side with lots of lovely detail on the top, there will be a special edible prize for the Tarrywile Mountain Kings and Queens (multiple age classes) to help you get up there a bit faster! The quickest person in each category to get from control 5 to control 10 wins.
If you want to be eligible, please aim to start earlyish, as I'll give out the prizes about 1pm. Red course is just over 6 km.
