Owning a bike and being in a race doesn’t make you a cyclist. Have a look at the guy on the left of the picture.
Sadly, with his helmet on backwards, lazy brakes, platform pedals and sneakers, he’s right in the middle of other far better equipped competitors. He’s only one step above the guy I saw when I competed in the Mooloolaba triathlon in the late ‘80s. He was on a 27” women’s bike with a 3 speed internal hub and a full face motorbike helmet. I passed him on the bike which meant he was a better swimmer than me, and I have no doubt he caught me again in the run.
