I wouldn't sprint daily whether fasting or not, but try it for a few days, easy to remember what NOT to do after you do it.
(I suggest sprinting 2x a week max with enough rest days in between, if you're sprinting hard which you should be, your body will be aching the next day making that day's sprint something you'll want to re-consider)
Also, Martin suggests lower level activity in the fasted state. Weights are fine, but he also suggests walking if you find yourself wanting to do something fasted. Sprinting can be counter-productive in this stance.
I only sprint fasted, but only once a week, and sometimes my previous meal was a few hours after, sometimes the night before if I'm sprinting in the A.M.
