Maybe this should go in OW, but I'm curious to know how times compare pool to open water, if anyone can help.
I realise that weather conditions play a part, but lets assume that the lake is nice and flat and around 76F and I'm not wearing a wetsuit.
If I managed 23.50 for 1500SCM what can I realistically expect as a time for 2 laps of a 750m lake course?
