This or That:

Sun → Shade

Wave ← Nod

Bottles ← Gels

CLAYTON EXPLAINS: Simplicity. If I can get my hydration and fueling all at once, all the better. As an elite marathoner, the access to personalized fluids every 5K on marathon race day makes it easy.

Intervals ← Tempo

CLAYTON EXPLAINS: I find it satisfying to break down a workout into intervals. To have a moment to pause, breathe, evaluate the last interval, fight off the mental demons as the start of the next interval approaches, and then get after it. If the point of a workout is to simulate a race, in a tempo, you only get to simulate it once. In an interval workout, you get to simulate the race many times. And you have the chance to find the line—both mentally and physically—every time.

Hat → Sunglasses

Water → Sports Drink

Hills ← Flat

Half ← Full

CLAYTON EXPLAINS: The full marathon is a stupid distance. The challenge of executing a perfect marathon is insane—a feat that most people don’t have time for, nor should they. As a professional, I’m lucky enough to make it my craft. But for the average Joe? Half marathon all the way. Plus, you can run two, maybe three, quality full marathons a year. Whereas with a half, you could run one once a month.

Singlet → T-shirt

Grass ← Gravel

Warm Up → Cool Down

Loops ← Out-and-Backs

CLAYTON EXPLAINS: When you become a mileage junkie like me, there’s peace in taking the thinking out of running with a simple out-and-back. Yet, there’s nothing more satisfying than risking it all to create a new loop and having it be the perfect distance. And what’s the worst case scenario? If it’s short, you make another loop. If it’s long, all the better. (I told you I was a mileage junkie.)

Foam Roller → Massage Gun

Morning ← Evening

CLAYTON EXPLAINS: The anticipation of having a big afternoon workout looming over the first half of the day is the worst. Getting a good workout done in the morning and carrying that sense of accomplishment and satisfaction throughout the rest of the day is rewarding and almost gives you the license to do nothing the rest of the day.

Pants→ Tights

Chat ← Silence

Strava ← Instagram

CLAYTON EXPLAINS: Strava is the purest form of social media. The general expectation and even social permission to auto upload every activity on Strava as “Morning Run” with the option to add a cryptic title, monologue description, daily meme, or cringe group selfie takes the stress out of finding the perfect picture and writing the perfect caption. There is no fake on Strava. Meritocracy at its finest.
