GPP Hills Gradient

so how much is 5percent gradient again? about how much strides would 5percent grade make u take up 20m, if u take 13 strides over 20m on flat?

5% Gradient is a 2m rise over 40m. Not sure on strides over 20m, But considering the short distance and small slope I would say you would take the same number of strides as on flat surfaces.

What would stride number affect?

Jake- 5% is perfect. The materials I have say anything up to 7% grade for 30m.

If the hill is on a concrete surface does that negate the benefits of the lower structural stress of hill sprints? Therefore maaking normal sprints a more appropiate means?
