You know it’s going to be a tough workout when the e-mail outlining your running route concludes with a cheerful reminder that “What doesn’t kill you makes you stronger!”
The route in question on Tuesday: the Sligo-Ritchie loop, which my running group tackles on a semi-regular basis. The Sligo part is fine—Sligo Creek Trail is pretty, and pancake flat. Ritchie Avenue is the killer. My Garmin tells me it gains 110 feet of elevation over .4 mile—an average grade of around 5 percent (check out this calculator to compute grade). My quads tell me it’s closer to leg-presses or squats than running.
This hill sucked the life out of me when I first ran it last summer. It killed me again when I ran it last week. So I decided to do hill repeats on it last Friday, to conquer the hill mentally—and to increase my leg strength, boost my aerobic capacity and burn way more calories than I would on a flat route of the same distance (yep, more calories—keep reading).
In the September issue of Running Times, running coach Greg McMillan touts hill repeats as among the best workouts for half-marathoners, as they improve both aerobic capacity and your body’s ability to clear lactic acid after a hard effort.
And you can count on a 10-percent increase in calories burned for each degree of incline when you’re running hills, Dr. Jana Klauer, a weight-loss expert, told Runner’s World. This means running on a 10-percent incline actually doubles your calorie-burn.
Here’s how: Find a short, steep hill that takes about a minute to run up; or a medium hill that takes about two minutes to run up. Run uphill, jog downhill. Repeat. Check out this Running Times story for more specifics.
My hill workout Friday hasn’t translated into actual fitness gains yet, so the hill was as physically exhausting as ever on Tuesday night. But when I got to the top, I got a serious mental boost from knowing I didn’t have to turn around and run it again! Despite the hill, and 90-plus degree temperatures, I averaged 8:30-minute miles for the 4.7 mile route, which doesn’t include a .78-mile warmup and a .76-mile cooldown (6.24 miles total).
