This is the 02/04/03 practice swum by my husband, Kermit. He did this in a 20-yard pool.
EZ 100 swim
Straight 2000 freestyle, trying to maintain same stroke count for every lap. Checked time at the 1-mile point (36 minutes).
10 X 20 freestyle as FAST as possible. Don’t worry about stroke count. Take 10 bobs as recovery between each 20.
