swimming 13:00 [2] 0.6 km (21:40 / km)
Tried to swim By breaststroke, but felt some pain in the knee. After that I had to change to freestyle. My respiratory system isn't good enough for freestyle or then the problem is my technique. I don't believe that the problem is the technique, because I try to take as much oxygen after every right-side stroke.
So I did 4x100m and then some really easy breaststroke.
