Interesting Story
My running career began through shameless bribery. When I was 11, my parents started training for their first marathon. I was surprisingly hesitant to join them, even though I had been part of a running club when I was younger and loved the sport. One time, in an attempt to get me to join them, they said, "If you run with us today, we'll take you to get a calzone afterwards!" I had never eaten or even seen a calzone before, but I knew it was a combination between a pizza and a burrito. And knowing that those two things were phenomenally delicious, I could not turn down this offer. So, I went and ran 6 miles with them that day, ran my first half marathon a few months later and fell for a sport I am still madly in love with to this day, 20 years later.

"It's not about how hard you hit; it's about how hard you get hit and keep moving forward."
Favorite Running Memory
In 3rd grade, I ran a local Junior Olympics mile race. Through the first two laps I was in dead last, but my dad was on the sidelines coaching me through it, and I had a strong second half. I passed the leader with 3 meters to go and got my first victory in a race, with my friends carrying me on their shoulders after getting the win. And the rest is history.
