For me, there's a lot of expectations and you want to be able to live up to them.

My faith is the reason I run - it calms my heart and makes everything feel like a lift. My speed is definitely a gift from Him, and I run for His glory. Whatever I do, He allows me to do it.

And as long as I'm passionate about the sport, I'm able to do that and I'm happy, then I would love to do another Olympics. I'm just going to see how I'm feeling.

What's really heavy on my heart is fighting physical inactivity.

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

The most important lesson that I have learned is to trust God in every circumstance. Lots of times we go through different trials and following God's plan seems like it doesn't make any sense at all. God is always in control and he will never leave us.

My speed is a gift from God, and I run for His glory. Whatever I do, it all comes from him.
