Desiree Linden drank champagne from her running shoe after she won the Boston Marathon in 2018.
That victory broke a 33-year losing streak for the US — Linden was the first American woman to win that race since 1985.
"It's a lot of years of really hard work paying off," Linden told Business Insider.
She's at it again this Marathon Monday in Boston, where racers have kicked off the 55-degree Fahrenheit Boston course amid drizzly rain and light wind.
The grey sky conditions have some wondering if Linden might pull off another marathon win today.
Whatever the conditions when she's running, Linden said her simple mantra is "calm, calm, calm," since she believes you can't force your way into a successful run.
"You have to let the fast come out of you," she said.
