I’ve done this main set before (or something very similar), but I’ve adjusted the intervals to push myself a little harder. My mind was on tomorrow’s workout, which is stroke technique. However, I do like this set. It’s just enough distance to make it a push, but short enough to bring it home hard. The last 300, I wanted to swim the 300 under 4:15 (or average better than 1:25/hundred). I didn’t get my goal, but it was a good, hard swim. And those two sprints? Eh, not as sprinty as I would’ve liked.
