To be the best Triathlete you can be, you need to swim with the faster swimmers, bike with the faster cyclists, and run with the faster runners.
As Maverick and Goose proclaimed in Top Gun, “I feel the need, the need for speed!”, we triathletes might similarly proclaim I have the desire for speed. So how exactly does a triathlete go about fulfilling this need? We could just go buy a fast car, or in my case, a fast motorcycle, but aside from the visceral thrill of that it’s not going to improve our 5k/10k run time in a triathlon. No, we have to dig a little deeper, push ourselves a little harder, and get focused in our training. This brings me to the topic of doing speed work on the track.
