Fartlek Swim (kinda)

I had intended to swim drills and then do a mixed pace set but Friday morning crowding of the lane made that impossible. Therefore I switched into the fast lane and spent the session trying to keep pace with the faster swimmers over short bursts.

Overall session was 200m wu, drills and then 30 min or so of mixed pace swimming, 50 min all in. Note: Left shoulder gives me jip in the warm up.
