16 x 200m @ 75% w/ 45s recovery…..WOW…..are you a miler? That is not an appropriate workout for a sprinter in my opinion…even for long sprinters. If you are actually sticking to that percentage it probably means you'll be running 2 miles at about 4 minute mile pace.
That looks like a workout that I've seen for Nouredine Morceli.
