I had an early morning meeting downtown so I swam at Life Time in the late afternoon in the outdoor 25 meter pool. The weather was perfect, and the water temperature was just about right. I used my handy digital finger lap counter as a pace clock.
500 swim, 300 pull
8 x 50 @ 1:00, drill/swim
5 x 300 @ 4:30, moderate/En2, held 4:15 or better
