TV presenter takes on epic 500mile triathlon for Sport Relief
As Big Brother presenter Davina McCall currently battles her way through Day 6 of her ongoing triathlon from Edinburgh to London, we take a look at her progress so far...
Setting off from Edinburgh Castle at dawn to take on 130miles of cycling on her first day, Davina finished in the Cumbrian town of Keswick after battling 50mph headwinds, sleet, hail and snow.
Keswick to Windermere was the next day's leg, starting with a cycle to snow-covered Scafell Pike, followed by a climb up and down England's highest mountain, then back on the bike to cycle 9miles to Windermere.
Having never taken on open-water swimming before, many 220 readers will be troubled by the next challenge – swimming 1.5miles in bitterly cold Lake Windermere, where water temperatures were as low as 5ºC.
After having to be dragged out following completion of the challenge (deemed dangerous and bad press for open-water swimming by commenters on our Facebook Page), she set off for a 60mile cycle to Accrington in Lancashire, pulling in to what Sport Relief called a hero's welcome.
Day 4 involved a 45miles bike ride "cold as you like" and 7mile fell run on her way to Edale in the Midlands.
Davina set off from Edale yesterday for a 90km cycle leg to Birmingham, pulling in to the Bull Ring after dusk having averaged 9mph in temperatures around 2ºC, burning an estimated 7,000 calories.
Today's session requires a 100mile cycle from Birmingham to Windsor, where she will then gird herself for the final 26mile push into London Town on the seventh and final day...
