Cotswold 113 Middle Distance tri.
Swim 1.9km. That's a distance I'd use the car for.
4 waves of swimmers, and by request I was placed in "an appropriate" one. ie, last. Looking around, everyone with my colour hat seemed to be nervous, so I thought that I'd just swim. Soon I was with others of similar inability, and we went round the course at our pace. I even drafted a couple of times.
Given my pool times, I expected that I'd take 50 minutes. Amazingly I was given a chip time of 42:28. I can only guess that the wetsuit and calm conditions helped.
Out of interest I looked behind me. Out of 630 athletes, there were still 6 in the water. Result!
