Long intervals or short hill sprints for your next workout? Trick question. The answer is both! I like to combine different training elements from time to time to keep workouts interesting and help us get a little something extra out of them. In this workout, we’ll “interrupt” a session of 2-mile repeats with two 10-second hill sprints at near max effort. Here are the details:
What: 2-4 x 2 miles at marathon or half-marathon pace with 2 x 10-second uphill sprints between 2-mile repeats. After running 2 miles at your intended pace, recover by jogging easily for 2-3 minutes (if you’re closer to marathon pace, take 2 minutes recovery; half-marathon pace, take 3). Then run 2 x 10-second sprints on a steep uphill at a hard effort, walking slowly downhill (take about a minute) between hill sprints. After walking downhill following the second uphill sprint, repeat the 2-mile/2 x 10-second hill sprint sequence 1-3 more times. (Note: After finishing your final 2-mile rep, you’re done! No need to tack on two more 10-second sprints.)
Why: The uphill sprints recruit more muscle fibers while also rapidly increasing the level of muscular fatigue in your legs, making it that much more of a challenge to maintain your rhythm on the the second, third, and/or fourth 2-mile efforts.
Where: Road, trail, or treadmill work best for this one. If you’re doing this workout outdoors, I’ve found the best options to be a loop that starts and ends at a hill or an out-back stretch from the base of a hill.
When: I like to use this as an early to mid-season workout (but not within 2 weeks of a key race).
Variations: As with most workouts, there are a number of different permutations and combinations you can play around with here. I outline a few others in this article I wrote for PodiumRunner a few years back.
