Long Runs For All

Why Non-Marathoners Still Need Long Runs

Long runs help you race better at any distance

In November of 1961, legendary coach Arthur Lydiard told the 1960 800m gold medalist, Peter Snell, to go run a marathon. Before that, Lydiard had Snell incorporating the Waiatarua circuit, a grueling, 22-mile long run up and down the Waitakere Ranges in New Zealand, as part of his 100-mile training week. What was a man who would race for less than 2 minutes doing running for 2 hours? This type of training was completely unheard of for middle-distance runners back in those days.

But it paid off.

Only two months after his Lydiard-mandated marathon, Snell ran a world-record mile (3:54). And in the 1964 Olympics, he won gold in the 800 and 1500m events.

The long run has been popular ever since.

Why is this? What are the physiological changes long runs produce that are beneficial to someone who is racing for a short period of time? According to Running Times columnist and coach, Greg McMillan, there are three key physiological adaptations that occur in the body during a long run: enzymatic, capillary and musculoskeletal. When you run long, you increase enzymes in your muscle cells and grow capillaries, which are the small vessels that surround the cells. These important changes allow more oxygen to be delivered to working muscles. You also strengthen your muscles, tendons and ligaments. "These adaptations help you in shorter races like the 5K because it's still primarily an aerobic activity," McMillan says. "The more oxygen that you can deliver to the working muscles, the better your performance will be. And the stronger your muscles, tendons, bones and ligaments become, the more you are capable to conduct better race-specific training like intervals."
