Hell o'the Mynd

Find out whether your legs and your head can deal with constant climbing and descending on often pathless terrain, following some vagueish instructions and a sketchy route map, to visit hidden checkpoints around a largely unmarked course. All of the first 21k loop (clockwise), and a bit of the second (anticlockwise) will be in the daylight, but at some point it'll get dark. And probably quite cold. Wet too... You'll have to remember where you found the checkpoints, and navigate to them in the murk. No medals, no bling, just a certificate, a beer, food and the kudos of completing the course await you. 3 distance options. Total 5000m of ascent on the long course.
