A few weeks back, I wrote about how I’m giving up on ultrarunning to pursue a new challenge - running fast.

What do I mean by “running fast”? My ultimate dream goal is to run under 15min for 5km. I ran 8:54 for 3km a couple of years ago, so I think (hope) I have the potential for a sub15 performance. I just need to hold the same pace for an extra 6min….

As I transition away from being an ultra-marathon runner to a track athlete, I find myself delving into the realm of anaerobic work capacity, critical power, and the power duration curve. Anaerobic work capacity refers to the physiological ability to perform high-intensity activities that heavily rely on anaerobic energy systems, specifically the phosphocreatine and glycolytic pathways, which generate energy without the need for oxygen. It plays a crucial role in shorter-duration races, such as track events, where explosive bursts of power and speed are paramount.
