This week’s run workout is courtesy of Olympian and coach Ryan Bolton, a former collegiate runner-turned-pro triathlete who now works with athletes who range from beginner to elite. Excerpted from The Triathlete Guide to Sprint and Olympic Triathlon Racing, this VO2max Fartlek running workout is ideal for mixing a little speed into what’s likely a “holding pattern” in terms of your season and training. This is also a great session for those who are running on a home treadmill.
This is an excellent way to prevent your fitness from plateauing and your routine from becoming stagnant while still working towards the beginning of your season. Be sure to heed the efforts in this workout from start to finish in order to not wear yourself out too prematurely—allowing you to increase your VO2 max without falling into too much physical debt. Remember, the goal here is to stay at a pace that you could increase two “notches” faster if you had to. Stay controlled, and you’ll not only hit the goal of the workout, but also stay in a healthy zone.
It’s important to take a day or two of running and cycling rest after this session, and have an easier day before. When performing this VO2max fartlek, remember that the “off” intervals should still be at a fairly decent pace—not too slow.
