I've become more aware of it after seeing myself in a video, but the faster I go the more my legs try to overstride. Especially in races like the 4x400, I overstride for what I think is for more power/speed. Also, in the 800 it is similar.
I sometimes heel strike on runs but I've been trying to fix this and land mid/fore foot.
From what I've read, this essentially is like a braking force and slows you down as you have to exert more energy. (Therefore, not efficient).
Does anyone have any tips or what you have done to break this habit.
Also, will I become slightly faster if I change this habit?
My times are: 400 - 54
800 -2:02
If this matters
