A 200 yard swim. A 10,000 meter bike. A 1.5 mile run. A triathlon sprint. That’s Threshold Racing’s Pre-Burn Series.
Even if you’re a long-distance triathlete, more and more coaches are recommending athletes spend more time in shorter races. With that in mind, Threshold Racing put on a series of events they call the “Pre-Burn”. These 200 yard swims, 10km bikes, and 1.5mile runs are held in a pool, on a “Watt-Bike”, and over a 2-loop parking lot run. A “fast” sprint, this triathlon puts your heart rate into Zone 4 (better known by me as the “ouch” zone) and keeps it there for the entire race. At the same time, you still have to pace yourself all the way to the finish.
