"Super fast" describes Brittany - she ran a 2:33 at the Olympic Trials Marathon for 13th place - but she had never set foot on a trail. Since then she won the Pikes Peak Marathon and last month set the Course Record at Moab Red Hot.

"I had this stigma about trail runners in my head, like they all were burly with beards.  And there were wild animals out there."

"But then Covid hit, so no races. And someone said, 'Why not try an FKT'?  I had never heard of an FKT."
