Yeah, I thought about that one, but I don't think I want to swim in Blue Lake mid-summer. I think the water temps will be too warm for me. Anything above 70F and I'm going to have to ditch the wetsuit, I think.
So ditch the wetsuit and do it. Think of it as a race simulation. It will give you a chance to practice your transitions and maybe help calm some of the OWS anxiety.
