A full day, full body workout. Ten of Dartmoor’s finest clefts, cracks and crevices to be climbed in a single push, on foot, starting at any point on the circuit but finishing where ever you started.
Style by choice, lead all, alternate leads or solo. Best fun is to probably alternate leads and try to pick the easier half.
Tape and fast growing skin is probably a good idea as is an interest in the dark arts of wider crack climbing.

Update for 2025, replacement of Levitation Direct with Fist and Buttock Clencher on Low Man. My apologies to anyone who has completed the original list, but always felt Levitation Direct was the weak link on a tour of thrutches. I had long pondered the cleft that forms Fist and Buttock Clencher and had wrongly thought it the line of Thursday's Child E5, and had always discounted it on the grounds of difficulty. Just to look at the oozing gash the climb takes and the inspiring name made it inevitable that it would have to be a Thrutches Tour candidate now that it has been correctly identified, though missed in the Dartmoor guide.
