For me that's right up there with the difference between the fastest anyone's ever run a mile and the pace per mile of someone running an Olympic marathon. Both seem really weird in a way I can't put my finger on.
They jumped except for the swimmer who just got on the starting pole, adjusted his glasses, smiled around, stretched and finally started. He expectedly won.
He was not showing off, it was to show the difference between active people and top class pros.
Except that they're in a 50 meter pool, and I was in a 25 meter pool.
At one point I could run marathons in 3 hours, 50% longer than the winners. Now I'm old, and I'm trying to get back to running them merely 100% longer. That is unlikely.
Bit daunting for the rest of us, but a good source of advice and tips.
