My two metre tall friend – an amalgamation of the two JMs – said he’d come with me to find TPR once he’d popped the next piece into his huge three dimensional yellow plastic jigsaw.

I could see that all the other players at their low tables were struggling to complete their puzzles. It could be some time before JM would be ready, so I had a go at helping him. It was impossible. If only an ‘easy’ corner piece was left to do.

Then the organisers intervened to mess up the tables a little. At this rate nobody would ever manage to add to the building of their puzzles, never mind complete the challenge. I thought about making a complaint to our former lodger CW, who was serving as one of the stewards at the event.

This all put my earlier achievement into perspective. With Rob Brydon, I had won the Fringe Urban Orienteering Challenge, knocking our nearest rival into a distant second place (again). The organisers had not wanted to publicise our win because they were forced to withdraw the £100k prize at the last minute. This was due to funding cuts. Nevertheless, I was still determined to tell everyone I met about our amazing achievement.
