foot contact at maximum speed

[Charlie_Francis]

@iron_fox

charlie, when i reach maximum speed during a sprint, i continue making contact with the ground by only allowing the ball of my foot to touch and never my heel (and i have my big toe dorsiflexed). however, within a few meters i begin to lose my balance and start slowing down. i was wondering if this is a common problem or if you had any advice on correcting it.
thank you

I wonder if you are leaning forward to keep on te balls of the feet- or being forced forward in the attempt. I suspect you’re better off concentrating on form and letting things sort themselves out naturally.
