BRAVE television presenter Davina McCall has set off up England's highest mountain today - despite being 'cold, wet and emotional' after yesterday's 130 mile cycle ride down from Scotland.

The celebrity, 46, has had to endure appalling weather conditions since setting off yesterday on day one of a mammoth fund-raising mission for Sport Relief.

She set off cycling yesterday at 7.45am and cycled for over 14 hours - enduring '50mph headwind, hail, sleet, snow and hell'.

Davina herself tweeted at the end: "I'm in tatters. That's the hardest thing I've ever done. 50mph winds, freezing rain...it's biblical."

She was also diverted an extra two miles but was described as in 'good spirits' although 'dog tired' by the time she got into Keswick late last night.

There have been national newspaper reports that she is at risk of hypothermia and experts suggest she has burnt off 6,000 calories alone yesterday - managing an average speed of 11mph on her way to Cumbria.

The star - perhaps best known for her stint presenting C4's Big Brother - had never cycled more than 90 miles before.

Starting at Edinburgh Castle on Saturday, she is aiming to cycle, run and swim a 500 mile triathlon in just seven days - finishing in London.

She is understood to have set off up 3210ft Scafell at around 9.30am using the Seathwaite route. There are wind gusts expected over Scafell of 70mph and possible blizzards today.

She will trek through snow on Scafell and will then descend down into Great Langdale this afternoon in a six mile (11km) walk.

She then has to cycle to Windermere where a swim in the perishing cold of the 10.5 mile long water awaits her.

Her support team has warned this morning that her 'knees are in pieces' and described the route up Scafell as the 'world's biggest step class'.

Many celebrities including Match of the Day presenter and former England striker, Gary Lineker have tweeted their support.

The aim of the event is to raise money and inspire other people to go the extra mile for Sport Relief.
