To put that another way, a brisk walking pace would be around 4 mph.

Mu won her race running at around 15 mph.

Im not trying to do anything beyond myself, she tells SELF.

Im just going to be the athlete that I have been the past year and some change.

As committed as she is torunning fast, Mu takes her recovery and bedtime routine just as seriously.

I didnt have time to be myself; we were always together, she says.

Before I even start my routine, I take my dog through his.

Bentley and I go on a little walk and then I get him his dinner.

Most of the time when Im getting ready for bed, Im exhausted from training.

I always moisturize the rest of my body with someJergens Shea Butter, the best lotion ever.

It smells so good.

Then I put on my glasses.

Then I turn on my Levoitair purifier.

I was like, I need that!

So I got one.

By this time, my phones probably down by now.

I find that Im not on it as much as I was when I was in high school.

Back then, I didnt put it away before bed.

Now I do, because I just dont use it that much.

If Im nottooexhausted, I turn onReal Housewives.

Thats my show right now.

Im watchingseason 7 of Atlanta.

Binging shows is part of my relaxation process.

Im also readingIf He Had Been With Meby Laura Nowlin.

It just depends on my mood.

I know Ive been getting good sleep because I wake up and it feels time to wake up.

I guess that means my body is well-rested.

Everything I do to prep for bed is very simple.

I don’t like being too complicated.

Its the little things that build up together to make you comfortable.
