Borrowing an idea from our mutual friend Nicole Antoinette, Kate has decided to choose courage over comfort when it comes to showing up and racing.

When it comes to getting the most from our bodies, all of us have some trepidation about the discomfort of racing. It can be unpleasant and downright painful. But deciding to "go all in" and embrace that fear is the only way we can reach our potential.

It's not an easy choice. Comfort is far easier: the comfort of sleeping in, not signing up for that big race, or not pushing hard during the final mile.

But comfort can be the invisibility cloak that masks failure. After all, if we're only operating at 85%, are we really thriving?

Today's conversation with Kate Grace covers many areas of training and mastering your inner psychology:

• How she handles workout anxiety and pre-race jitters
• What she does to stay in control of her thoughts during demanding speed workouts
• How she talks to herself in fearful situations (like standing on the starting line of a major championship)
