While we all run at different paces and in different places, many of us share a common goal — to get faster. It might be faster than your buddy, or faster in your next race, or even faster than yesterday…but the minute you hit “stop” on your watch it’s running human nature to start doing the math on how you can improve. Problem is, with so many programs promising fast gains, the vast majority of runners don’t conceptually know how to begin getting faster. Should you run longer? Should you cap your heart rate? Do you need to go faster? Is it the shoes? The answer, actually, is closer than you think: if you want to become a faster runner, you need to focus on the pace your running muscles can sustain.
