Ah, the sprint is being rediscovered once again for it's ability to squeeze maximum effect into minimum working time. If you get a chance, try to find a copy of "A System of Multi-year Training in Weightlifting" by A.S. Medvedyev (a translation of the 1980s Soviet Olympic Weightlifting program for coaches). It's the culmination of decades of studies across the entire Soviet athletics program about what works and what doesn't. The summer programming shifts almost exclusively to sprinting, and only a few hundred meters per day, because that's what they found is enough work for anyone who isn't a specialized running athlete. I follow it as soon as I can ever summer and it's immediately obvious that my metabolism increases. IMO the secret about sprinting vs distance running is that your body can't optimize for efficiency. You can marginally increase ATP capacity, but the only thing getting better at maximum effort sprints does is make you able to produce more power while doing maximum effort sprints. It stays hard, without needing to increase volume much over time.
