Having upgraded one of my 1948-vintage ankles to the latest 2025 model a little less than ten weeks ago, I thought it was time to test it underground. The new ankle is an excellent colour match for the other, but unfortunately it's a lot fatter, which meant I couldn't get my wellies on and had to wear a pair of clunky canyoning boots. However, a pleasant but short trip from Manchester Hole through to Church Pot via Eternal Optimist gave me hope that I might be back to normal by the CPC winch meet.
