If you had to pick one race or event this year that you anticipate will be your most proud achievement or moment, which one would it be and why? Do you have a special connection?

I am competing in a 2-day, single elimination obstacle course race on the beach this upcoming May. I'm excited about it because there are only a handful of athletes who have been invited to compete in the Pro Division and all of the female athletes who will be competing are incredibly strong contenders! Simply getting the invite is an honor in and of itself, but to win this race would be quite an achievement amongst such a stacked field. It's also a brand new race series and I love supporting newcomers because I want to see this sport grow!

Do you have any quirky running habits?

Not that I can think of but maybe I should start some... 



Eat a slice of pizza mid-race or drink a milkshake?


Run on an empty stomach or a full bladder? 

If I could go to the restroom behind a tree, full bladder all the way! 

Do a beer mile or a milk mile?


Run in the freezing cold or the sweltering heat?

Freezing cold. 

Be met at the finish line with your favorite beverage or favorite meal?

Favorite beverage—fresh lemonade. 

Come across a snake or a rat on your run?

Rat all day. 

Run with a blister on your foot or a cramp in your side?

Oof... probably gunna go with blister. 

Give up core work or stretching and still stay injury-free?

Not a chance. 

Run uphill in the first half of your run or the second?

First half! Get it over with.
