February 13, 2014 - 11:28 GMT hellomagazine.com Davina McCall is continuing with her Sports Relief challenge to travel under her own steam from Edinburgh to London by swimming, running and cycling Davina McCall has been updating fans throughout her mammoth Sports Relief challenge. The TV presenter has been posting photos and tweets as she continues to travel 500 miles under her own steam, running, swimming and cycling from Edinburgh to London. Davina, who dramatically collapsed due to suspected hypothermia while swimming across Lake Windemere, met with Great British Bake Off presenter Mel Giedroyc on Thursday. "Mel has brought me some great British biscuits of hypothermic swimmers," tweeted Davina in reference to her recent accident. "She's really cheered me up!!!!" "Today was so tough," read another tweet. "The head wind and gusts were really depressing and slowed us down a lot @sportrelief." "Seen so much flooding on our trip. Am thinking of anyone affected by this terrible nationwide catastrophe" Davina's trainer Greg Whyte, who also coached David Walliams when he swam the River Thames for Sports Relief in 2012, has also been posting photos of The Jump presenter. "Day 6 in the @ThisisDavina @sportrelief #BeyondBreakingPoint house," he wrote. "Big day in the saddle ahead. #davina is on Radio 1 in a mo." "If you wondered what it was like out on today's 90 mile," wrote Greg with a picture of himself wearing rain covered glasses. "#BRUTAL." Davina, 46, is due to finish her epic journey on Friday. On Monday the exhausted star had to be carried out of the water after swimming across Lake Windermere, undergoing a series of medical tests amid fears that she was suffering from hypothermia. The mother-of-three, who had admitted she was terrified about the prospect of the one-mile swim, managed to conquer her fears and complete the stretch. But she had to cling on to a support kayak as she was taken over to the dock, and was unable to stand once she reached solid land. Davina was then carried from the water's edge to a nearby hotel by a member of the crew – and pictures later posted on the Sports Relief Twitter page showed her wrapped up in blankets as the medical team attempted to raise her core body temperature.
