Sprinting Percentages


#1

Most sprinting programs are based on sprinting percentages, and I'm curious what is the best way to determine these percentages on the track. Every time I sprinted i used to go at full speed, and it is probably not the smartest choice, especially when i want to use sprinting as some kind of conditioning and supplemental work for my strength/mass program.

You make an estimate of the effort and remain consistent.

For 90%, I knock a bit off the top speed.
For 75%, I go at what feels like 3/4 speed...

Goal time / percentage (in decimals)

If you can run a 50 in 6 seconds and want to run it at 75% intensity:

6/.75 = 8 seconds

We build up with some reps at .50/.60/.70 as warmup sets to get a feel for what each intensity feels like. Eventually you'll be able to guess within a second how close you were to your goal time.

If we are running a different distance, we just figure out the time needed for the longer distance and divide accordingly.

Thank you for the answers.
