Confused water and confused muscles

I went to the river this morning and paddled for 100 minutes in bright sunshine.  A stiff northwest wind kept the temperature below 60 degrees Fahrenheit.

After warming up I did six of those pieces where I follow a few back strokes with six hard forward strokes.  Then I spent the rest of the time doing a loosely-structured workout where I did sprints of varying lengths with long recovery periods.  Parts of the river were quite choppy because of the wind, and a lot of my attention was occupied by balance and control issues.  Once again, my muscles were firing in sync some of the time, but not all of the time.  I'd like to achieve more consistency with that.
