Notes
good session - swam longer AND faster than last one...rest breaks were shorter, too...
started out with 300 continuous in 5:52 (so was averaging under 60 seconds per lap for the first 6 laps - actually swam 1st lap in 49 seconds)
then swam a mix of 150s and 200s for rest of session
hit the 10 lap mark in 10:03
hit the 20 lap mark in 20:32
