When I share with other runners that I’m actively participating in CrossFit, I get bewildered, almost concerned, stares. “Those workouts look crazy; like you’re going to die. You like that?”

Well, not dying. But, yes, I love testing my limits and being humbled (or flattened) by a new and growing sport. Simply put, CrossFit is a workout methodology using “Constantly varied, functional movements executed at high intensity.” That sounds manageable, right? As a former collegiate athlete, I appreciate the desire to get better every day, seek new challenges, and be a part of team, something running couldn’t offer me entirely, even though I adore it.

But do you really have to choose between CrossFit and running?

Let’s back up a bit. A little over a year ago I labelled myself as a runner. My very first race was a full marathon, but I caught the racing bug and kept training. However, the beginning of plantar fasciitis reared its ugly head and I had to limit running. But, I still wanted—needed—to be active.

Enter CrossFit.

I began CrossFit on my own, modifying the prescribed WOD (Workout of the Day) using the equipment I had available. At first, I questioned whether I could get an effective workout in just 20 minutes when I would normally run more than 90 minutes at a time. However, during those 20 minutes, I was pushing myself outside my comfort zone, well outside. I was uncomfortable. Challenged.

Once I joined a CrossFit box (the local gym where workouts take place), I saw a higher level of intensity and experienced instruction. While the experience varies between boxes, for me, skilled coaches broke down movements from power lifts to pull-ups. They offered scalable modifications for a new participant like me to perform safely.

With CrossFit, new movements or intervals brought on a novel sort of discomfort. Strangely, I was hooked. I craved that uncomfortable state that tested my tolerance and limits. My body never adapted to a WOD like it had to 10 miles on the road at a steady pace. CrossFit never got easier because I had to continually push harder.

And I was seeing physical changes: more muscle definition, strength, improved flexibility. But I still loved running. There’s something peaceful about hitting autopilot for an early morning run on the open road. So I made a decision to do both.

I believe CrossFit compliments my running performance. Some of the most fundamental movements in CrossFit—like squats, kettlebell swings, pull-ups, and push-ups—are among my favorite exercises to improve running performance. And, I’m not alone in my quest to combine both CrossFit and running into one active lifestyle. CrossFit Endurance is a strength and conditioning program dedicated specifically for endurance athletes. While I don’t follow its training plan exactly, I think there is a lot to be said for their model of reducing running volume while increasing intensity—and becoming a stronger athlete and better runner in the process. For example, many CrossFit workouts incorporate sprints in addition to other movements, kind of like speed days within a 5k, 10k, or half marathon training cycle.

Here are a couple of examples from my own CrossFit box:

20 Minute AMRAP (“As Many Rounds As Possible” in 20 minutes)

  • 10 dead lifts
  • 10 pull-ups
  • 800m run

WOD for time (meaning as fast as your tired body allows!)

  • 10 power cleans
  • 400m run
  • 7 power cleans
  • 400m run
  • 5 power cleans
  • 400m run
  • 3 power cleans
  • 400m run

Even before I had access to a CrossFit box, I created my own workouts that combined both running and strength training and could be performed anywhere. Below are two of my favorites:

5 Rounds for Time

  • 200m sprint
  • 15 burpees
  • 15 plank jacks
  • 15 hand release push-ups
  • 15 overhead squats

6 Rounds for Time

  • 800m run
  • 10 push-ups
  • 20 squats
  • 30 full sit-ups

Final Takeaway

During WODs, I learned to run on tired legs, which is exactly what happens towards the end of a race, especially a hilly one! Most recently, I was able to cut 4 minutes off my 10k personal best time. I have this combination of training methodologies to thank.

My body is stronger overall and I have avoided injury since incorporating CrossFit. Running brings me joy on the open road and during a race, but CrossFit delivers variable, high intensity workouts that will always keep the athlete in me coming back for more.
