Racing has always been a bit of a hit or miss proposition for me. Even though, going into a race, I’m confident that I’ve adequately prepared myself to run well, some results tend to be better than others. While it may be impossible to pinpoint the exact reasons for failure, when I take a look back at my best racing performances, there seems to be one consistent reason for success: “negative splits”.
For those who don’t know, running negative splits means running slower early miles and faster later miles. As a result, your split times descend, or move in a “negative” direction, as the run progresses. The theory is that starting slow allows your muscle cells to warm up and take on huge volumes of oxygen before the really hard work begins, attenuating anaerobic metabolism and spiking fatigue-resisting aerobic energy production. Simply put, running negative splits allows your engine to warm sufficiently before shifting into overdrive!
