Highlights of day three of Greg James's epic challenge.
Having cycled through the blizzard, today was all about climbing England's highest mountain, Scafell Pike in Cumbria.
But with the snow up to his knees, and an air temperature of minus 20, can he make it up?
Afterwards, Greg gets back on his bike and races to meet Radio 1's Adele before the end of his show.
