If your run feels like it’s stuck in one gear (your 5K pace and your long run pace are similar) then it pays to do some speed work!
VO2 max is the intensity at which your body maxes out in its ability to uptake oxygen. Training at this intensity raises your cardiovascular system’s ability to perform this task. For the athlete that means one of two things: either you will be able to run faster or your old pace will feel easier, allowing you to hold it for longer durations.
You can typically find your VO2 max pace by performing a good, all-out one mile time trial. So before attempting this workout, you should know your absolute best one mile time. Run the time trial on a flat surface like a track. With your mile time in hand, divide it by 1.61 to get your minutes/kilometer pace. This is the pace you will use for the following workout.
- 15:00 easy run
- 5:00 dynamic stretching and muscle activation exercises. Some examples below:
- Soldier aka Frankenstein walk
- Walking lunges
- Heel and toe walks
- As + Bs + Cs
- Repeat 20x: 30 sec @ VO2 max pace, 30 sec walking recovery
- The very short recoveries in this workout keep heart rate high, maximizing the total volume at VO2 max.
- 10:00 easy run
- Static stretches
Work your way up from 20 repeats to 30 in three to four weeks.
Perform this workout early in the build phase if you’re training for long course, or later in the build phase – just before racing – if you’re a short course athlete.
