Helen Skelton

BBC Blue Peter presenter Helen Skelton is now only days away from completing her Polar Challenge for Sports Relief.

With just under 100 miles to go of her 500 mile trek to the South Pole, Helen's biggest problem is now exhaustion and extreeme cold with temperatures going as low as minus fifty degrees.

Helen has made use of skis, kite-ski and a special pedal bike to complete the challenge and it looks like she will have broken some world records along the way.
