So in swimming lessons level 9 we swim 400 meters or 16 laps of 25m in the lake, we all got the time of 21 minutes, were not competitive.
Is this a good time? We do 100m front crawl, then 100m back crawl, 100m elementary back stroke, 50m breast stroke, 50m freestyle which we usually do front crawl. Is 21 minutes a good time? We swim between buoys in the lake.
