• 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 efciency
and, like golf, a lower score is better.
• Your swim efciency 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
efciency to another pool or an open
water workout. A lower swim efciency
index is better.
