The ride was absolutely lovely. So I will sit and the sun and enjoy the day. I feel like a real triathlete now.
I finished the day with 1250 m lap swim. My coach corrected the angle of my arm entry. Progress. I can do this!
So, I am left wondering if there is a "preferred way" to land when you crash your bike. It happens again, should I try to tuck my arm and leg in, and fall flat? I think from the bruises and road rash that I must have stuck knee and elbow out to catch myself as I went down. Not effective and could have resulted in more injury, in hindsight. My whole right side hurts a bit - hip, shoulder & neck. I will replace my helmet, though I think I didn't hit, or didn't hit hard at least - when I slid into the curb. (now I will have proof that I am an triathlete!)
I take away confidence that I can handle sudden & unexpected events calmly. I was up on my feet and out of traffic quickly. Fixed my bike chain and rode home.
