Do you ever wear Speedos that aren't yours?

[Torchwatch]

While still at school my athletics club sent us down to Hastings on the South coast for a distance relay race. The course was around a big ornamental park running on tarmac paths.
Just before the race my friend Andrew said he didn't have any shorts and could he borrow mine. We arranged with the team manager that I would run 2nd leg and he would run 4th and last leg.
I ran the course, hot and sweating I touched hands with the 3rd leg runner in the transfer area. Andrew and I dashed into the pedestrian underpass between the park and the sea front. With cars passing overhead I stripped off my still warm and sweaty shorts and passed them to Andrew who slipped them on, I then pulled on trackies to hide my rather brief briefs before anyone came by and saw us.
They were Umbro running shorts, really short black slightly waxy nylon with a slit up the sides, they had white trim. I had a similar red pair with black trim, they were my favourite running shorts at the time.
