Hard physical, easy swim workout

It alarms me that two swimmers suffered cramps during the swim workout today. Physical was hell, yeah I know, but the swim workout today was an easy one. Perhaps there wasn't enough swim conditioning? Hmmm ... something to look into.

I'm also quite disappointed in the swimmers' stroke techniques today. Still quite messed up despite two days of stroke corrections. I'm planning aanother stroke correction session tommorow. But should I ...?
