An almost unbelievable achievement, one of the most significant in Peak Climbing history.
However, contrary to reports on UKC and in the OP above,Tom and Pete didn't climb all the Brown and Whillans Peak grit routes. They (intentionally) missed off the 14 routes in the Chew and Longdendale Valleys. Adding these to the Eastern and Staffordshire collection done by Tom and Pete, and doing the lot in under 24 hrs is the obvious extension to the challenge!
