There's 3 categories on how to split races
1) Correct splitting, which means taking our races out at just the right effort level to maximize your time in the event. Take it out right and finish tough.
2) going out too hard and dying
3) going out too easy and not swimming the best possible time
Correct splitting begins with the 50 and goes on out to the 1,650 and beyond for you open water swimmers.
One way to measure splitting is calculate the split difference.
to subtract the time from the last half of the race from the first half.
Last half time - first half time = split difference
After studying elite swimmers splits for many years here are some guidelines on how to split races when you compare the first half to the second half.
50's Fr and Back 0.5 - 1.0, Breast and Fly 1.0 - 2.0
Effort: you want to swim fast and relaxed with a super strong kick
99% effort
100's Fr and Back 1.0 - 2.0, Breast and Fly 2.0 - 4.0
Effort: you want to swim fast and relaxed with a strong kick
98% effort
typical 100 freestylers take out their 100 free about a second slower than their best 50, so if you go 20.0 in the 50
you should be around 21.00 taking out your 100.
200's Fr and Back 0.0 - 5.0, Breast and Fly 2.0 - 6.0
200's are controlled sprints. When we compare the last 3 50's
the better swimmers will keep them very close together
Effort: Warning if you take your 200 out too hard,
it's going to hurt and
you're not going to do the best time you're capable of.
