The water is still maybe around 61-62* at the lake where we have tri practice. Tonight it was cold and rainy - when I got out and got in my car, it was 57*. I managed 1.5 mile (3 loops), no wetsuit, before calling it a night.
I don't like anything near my neck/around my shoulders, and prefer swimming unencumbered, so I haven't shelled out for one. There's only a small handful of early season swims where it's really cold.
I can't even deal with those zip up racing suits for pool swimming. I like feeling more naked and free
Brrr is right! Good for you that you got out there! I would have been a pansy and opted out when I looked at the air temperature, forget about the water temperature. Super badass!
