When , the two-time revealed plenty of details about her extreme fitness regime. But she also made clear that much of the work it takes to become the first American woman to win the race since 1985 is mental.
1. Use the 40-percent rule.
"When we think we're down and out, there's still a little bit more," the runner told Business Insider's Áine Cain. "It's figuring out where the very bottom of your well is. And every time you're, like, 'Wow, that was a little more than I thought.' You can keep pushing that threshold."
This insight isn't unique to distance runners. : Whenever you think you've hit your limit, you're actually only about 40 percent there. Reminding yourself that when your body (or mind) is freaking out, you don't necessarily have to take its warnings seriously is one great way to improve your resilience. But having the equanimity to stay calm and talk yourself through tough spots obviously benefits from practice.
2. Sleep enough.
"The best recovery tool you have is your bed. Just get sleep," is Linden's simple advice.
3. When the going gets tough, stay in the moment.
Linden isn't the only distance runner who recommends trying to keep from thinking too far ahead when the going gets tough. It's advice you hear from and again and again. Panic is far less likely if you get in the flow and keep your mind on the present. That's a truth you can put to use whether you're running 26.2 miles or giving a high-stakes presentation to a huge audience.
"Once you get out the door, it's, like, 'OK, just enjoy this step and this mile and this moment,'" Linden tells BI. "People tend to think about how much they have left or put a negative spin on it. Just being present in that moment is always really helpful."
