Just a swim today

I swam 4.1k this morning. I really liked the set leading up to the main set. It was 3x(2x150 50fr50bk50fr + 100k fast + 100 swim). I descended the kicks and the swims. The main set was 2x (250 + 350 + 400). Each distance the average speed increase and the rest decreased. I felt good during most of the workout.
