God, salt water makes all the difference. I swam in a salty lake and never once felt I was going to sink.
30 mins for the first 500m, facing forward.. Vertical swimming/ legs straight down..then on my back for the return 500m where my legs were straight out behind me – twice as fast, back in 15 minutes.
I’m gonna try again today with a little flotation foam stuck in my shorts, to see if I can stroke with alternate arms rather than both at the same time, which is a bit like doing butterfly on my back.
Mega thanks to Stu and Lucy for swimming with me, Ben and Lex in the safety boat, and Stu and Mark for lifting me into and out of the lake.
