Sprint training is becoming a new way to train.
In fact, one study found that just six sessions of 4-7 all-out 30 second sprints (with four minutes of recovery) could be as effective in improving cardiovascular fitness as an hour of daily moderate activity.

Short-term sprint interval versus traditional endurance training: similar initial adaptations in human skeletal muscle and exercise performance Brief, intense exercise training may induce metabolic and performance adaptations comparable to traditional endurance training. However, no study has directly compared these diverse training strategies in a standardized manner. We therefore examined changes in exercise capacity and molecular and cellular adaptations in skeletal muscle after low volume sprint-interval training (SIT) and high volume endurance... [...] ...In conclusion, the most striking finding from the present study was that two very diverse forms of training induced remarkably similar changes in exercise capacity and selected muscle adaptations that are related to exercise tolerance. Given the markedly lower training volume in the SIT group, our results suggest that intense interval training is indeed a time-efficient strategy to induce rapid muscle and performance adaptations comparable to traditional endurance training. Additional research is warranted to clarify the effect of different acute exercise ‘impulses’ on molecular signalling events in human skeletal muscle, and the precise time course and mechanisms responsible for the contraction-induced changes that facilitate the training adaptation.

I've seen that sort of thing before. Here's the thing: Higher intensity work will make you faster. That is an undeniable fact. That being said, your chance for injury will increase, your risk of burnout will go up, and you're not going to experience the long-term gains. Unfortunately, these studies generally only cover weeks of training, not months or years. I have yet to meet someone who could maintain high intensity throughout, every day, every week, all year long, for years.
Just because running is simple does not mean it is easy.
