Meaning: Frank Shorter, a renowned American long-distance runner, made this statement about the benefits of incorporating speed work into his running routine. Speed work, also known as interval training, involves alternating between periods of high-intensity running and recovery. Shorter's quote reflects his personal experience of finding joy and satisfaction in his running as a result of reintroducing speed work into his training regimen.

For endurance athletes like Shorter, speed work can be a game-changer. It not only improves running speed and performance but also enhances overall fitness levels. By engaging in high-intensity intervals, runners can push their bodies to adapt to different levels of exertion, leading to increased cardiovascular capacity and muscular endurance. This, in turn, can translate to improved race times and a sense of accomplishment for the athlete.

Shorter's emphasis on "enjoying my running more and more" suggests that the benefits of speed work extend beyond physical improvements. Many runners find that incorporating variety and challenge into their training can reignite their passion for the sport. The satisfaction of pushing oneself to new limits and seeing tangible progress can bring a renewed sense of excitement and fulfillment to the running experience.

It's worth noting that Shorter's endorsement of speed work is backed by scientific evidence. Studies have shown that interval training can lead to significant improvements in aerobic and anaerobic fitness, as well as overall running performance. The combination of high-intensity efforts and recovery periods can stimulate physiological adaptations that contribute to enhanced speed, endurance, and efficiency.

For those looking to incorporate speed work into their running routine, it's important to do so gradually and with proper guidance. Introducing intervals too quickly or without adequate preparation can increase the risk of injury. Additionally, varying the length and intensity of intervals, as well as incorporating different types of workouts (such as tempo runs and hill sprints), can provide a well-rounded approach to speed training.

In conclusion, Frank Shorter's quote highlights the transformative impact of speed work on his running experience. By embracing the challenges and rewards of interval training, he not only improved his performance but also found a renewed sense of joy and fulfillment in his running. Whether for competitive athletes or recreational runners, the incorporation of speed work can bring about physical and mental benefits that enhance the overall running experience.
