Interval sprints focus on short, high‑intensity bursts with rest periods, boosting anaerobic power. Tempo runs keep you at a steady, comfortably hard pace, enhancing lactate threshold. Hill repeats add strength and running economy by forcing you to power uphill. Which of these training formats do you think offers the best overall speed gains for a runner looking to shave seconds off a 5K? Share your pick and explain the main reason behind your choice.
