The club member cited, was a character, every time he got dropped there was a mysterious flat. So much so he was teased if he brought his tacks with him that day.
I don't know what caused the two flats that day at the time-trial, they were both on a back wheel I had not used before which a friend had given me, and at the bike race the second flat was had after a bike-shop at the race running a support service gave me a new inner tube for free and put it in for me and aired up the tire. I had ridden the bike to the event from home to warm up. Have not had a flat while on a bike ride since then, 25 years ago.
