Having done all my speed-training on asphalt and seeing that next week i will get access to a spurtan-track and get to wear spikes, what kind of time improvement could i reasonably expect ?
I got videofilmed during training today and my 60 meter time from a standing start seems to be 7.15 (Into a slight headwind ,on a [u]slightly/urising road,in the middle of a slightly busy road:mad:)
