Comfortable swim today

Went to the pool today and did 30 lengths, 750m. Apart from the screaming school kids who were also in for their 'learn how to thrash around in the water' lessons, it was a comfortable session. I really notice things improving and look forward to stepping up the distance over the next few weeks. The one thing I concentrated on today was pushing right through to the end of the stroke with each hand, brushing my hip on the way. It made a difference to the rhythm, which in turn helped the breathing.
