Whilst smashing the course record by about 12 hours, remarkably, she expressed milk for her baby daughter along the way.
A British Ultra Runner has become the first woman to win one of Europe's toughest races and smashing the course record by about 12 hours.
The 431-kilometre Montane Spine crosses the Pennine Way, from the Edale in the English Peak District to the Kirk Yetholm in the Scottish borders.
35-year-old Jasmin Paris ran the gruelling race in just over 83 hours, sleeping for a mere three hours.
She told Euronews what the toughest part of the race was for her:
"Two-thirds of the time you're running in the darkness, that really saps your mental energy. Because it's non-stop, it's tactical; the more you sleep the more energy you'll have. But equally your losing time every second you're sleeping, so there's all of that to factor into to it," she said.
"A lot of it is through quote remote areas so you're running on your own and that's a massive component. So it's draining from all sides. But I had the perfect incentive to get back to the finish, which was my baby daughter waiting for me there."
But what's even more remarkable, is that along the way, she expressed milk for her baby daughter at aid stations along the route.
Of the 104 competitors 24 were women.
