I just discovered that the lake where I do my open water swimming is open. I haven’t done any swimming since mid March. My first race, at the end of June, hasn’t been officially cancelled. It is a very small event and I think there’s a good chance it will actually happen. Logistically, I can probably only go to the lake once or twice a week. Distance and/or time based intervals don’t make a lot of sense to me in open water. Should I just go to the lake and work on endurance? I am using the Olympic Level 1 plan.
