Run at 80% for these reps...Check my math

No, don't do it that way. 27seconds divided by .8 gives you 33.75 seconds.

The long way to do it would be to convert your time into meters per second, then find 80% of that, then convert that back to time per 200m.

So 200m/27s is 7.407m/s

80% of that speed is 5.926m/s

200m divided by 5.926m/s is 33.75 seconds.

Coach says to run a 200 workout at 80% of current best, which is 27.0 sec for me.

I come up with 32.4 as the 80% speed. Is this correct?

27 x 80% = 21.6

27 - 21.6 = 5.4

27 + 5.4 = 32.4

That's Canova math. And it produces much faster runners than American math.

Your choice.

Thanks!

160m 27 sec is 80%

That's 4:30 1600 pace

Another way of expressing "Canova math" before we close the book on it is:

When he says "80% effort" it is like saying "20% slower"

So 27 x 1.2 = 32.4

But the previous poster is sticking to the word of what the coach said.

27 / .8 = 33.75

Makes even more difference if you were talking about mile pace:

For example:

5:00 x 1.2 = 6:00

5:00 / .8 = 6:15
