Free Back Breast Fly Freestyle Backstroke Breaststroke Butterfly 20 Mixed More than one stroke type in an interval Swim Terminology • A length is one trip down the pool. • An interval in swimming is like a lap in running. You can break your swim into swim intervals and rest intervals. • A stroke is counted every time your arm wearing the Forerunner completes a full cycle. • Your swolf score is the sum of the time for one length and the number of strokes for that length. For example, 30 seconds plus 15 strokes equals a swolf score of 45. Swolf is a measurement of swimming efficiency and, like golf, a lower score is better. • Your swim efficiency index is the sum of the time and the number of strokes that it takes to swim 25 meters. This allows you to compare your swim efficiency to another pool or an open water workout. A lower swim efficiency index is better. Training with Your Forerunner
