Sarah Storey fell short of breaking the world hour record on Saturday at the Olympic Velodrome in London.
The 11-time Paralympic champion was after the mark of 46.065km set in 2003 by Leontien Zijlaard-van Moorsel. She began strongly, but slipped off the pace by the halfway mark.
The 37-year-old did break the British record, however, by covering 45.502km.
Storey told The Guardian afterward that she suffered from cramps, calling the attempt “the hardest hour of my life.”
“In the first half hour you are thinking, ‘Oh, my goodness, I haven’t done 30 minutes yet.’ It was really tough,” she said.
“To break the British record is fantastic. I was hoping to go further than anyone else. Leontien was an incredible athlete and there’s no shame in missing out to her.”
