LONDON, March 18, 2013 /PRNewswire/ -- Leading car hire comparator Carrentals.co.uk has announced it will be supporting the Ski 4 Cancer charity on its latest fundraising scheme in France. Ski 4 Cancer will be staging a charity challenge in La Tania on the 20th and 21st of March, in which entrants attempt to ski either the vertical height of Mont Blanc (4807 metres) or Everest (8848 metres) in just one day. The challenge will focus on the green, blue or red pistes, which run adjacent to La Tania's main gondola, dropping from a height of 1900 metres to 1368 metres. With a vertical drop of 532 metres, skiers will need to complete 9 runs to ski the height of Mont Blanc and 17 runs to descend the equivalent height of Everest, dependent on their ski experience and ability. Gareth Robinson, Managing Director of Carrentals.co.uk, said: "We are delighted to be supporting Ski 4 Cancer and their Mont Blanc & Everest Ski Challenge. This type of challenge highlights how innovative fundraising efforts can be and allow those taking part to have fun whilst raising vital funds for such a worthwhile cause." Ski 4 Cancer provides alpine based respite days and short-breaks for British families affected by cancer. They also make grants to UK based care institutions and fund research into the positive effects of sport and how it can help both prevent cancer and assist in recovery post diagnosis.
