700m swim in a 50m pool (approx 20 minutes).
50m of this was freestyle, the remainder was breaststroke.
Breaststroke no longer causes me any pain. When doing freestyle, breathing is heavy and there is slight pain as I rotate my ribcage.
This is no excuse for only swimming 700m, I was lazy and should have swam at least 1.5km (I cannot lift yet, so I might aswell get fit).
As far as swimming goes, I aim to reach 2km in 40 minutes.
