Runner's World has story out where Shalane's HS classmates talk about watching the race and cheering her on. It it was said that Shalane has an official slogan of F.S.U for her marathons.

"I'm running the 2013 Boston Marathon and I'm going to f--- s--- up!"
- What Shalane Flanagan reportedly shouted at her 10-year high school reunion in 2010, according to a re-telling by a high school boyfriend, Tom McMahon. After that, her unofficial slogan became "F.S.U." which she reportedly had stitched in the inside of her shoes at the 2012 Olympics.
Both Shalane and her husband have let us know it's simply not true so we've removed the QOD.
