I love the relays. Track is such an individual sport, so it's fun to do something together.

Competing at the Olympics is the pinnacle of your career. Everything is amplified, and you feel so proud to represent your country. You're there with athletes from all over the world. Everyone is coming together, putting differences aside.

For me, my faith is the reason I run. I definitely feel I have this amazing gift that God has blessed me with, and it's all about using it to the best of my ability.

I spend around two and half hours on the track every day running and another 2 hours in the weight room lifting weights with my strength coach.

I focused solely on the sprints, dedicated my time there, got in the weight room, just really did everything I could to make sure I would be in the best position to run for gold.

As you get older, there are going to be a few more challenges, but thankfully I'm still feeling good.
