Scott Dunn, the sponsor of the Valley Rally Competition held at the end of the Varsity skiing trip, has vowed never to sponsor the event or the trip again after it heard of some of the lurid antics performed by students in the competition.

The annual Varsity Trip, a ski-and snowboard-trip for Oxbridge students, is the oldest and largest student run event of its kind in the world, having being held every year since 1922. The 2010 trip took place in Val Thorens, France

The Valley Rally Competition, held on the last day of the trip, involved teams of four competing in a set of challenges while racing around Val Thorens, the French Ski resort. The prize was a coveted 5-star skiing holiday in Saint Anton, Austria, worth £5000.

The challenges involved included breaking an egg “in the most creative manner possible”, eating buckets of snow, and posing for ‘adventurous’ photographs.

Wild imaginations combined with the extent to which some were willing to go for the 5-star ski holiday led to the outrageous acts that ensued.

The winning team, from St Anne’s College, Oxford, striped naked, some with pasta sauce and chocolate spread over them, in front of a crowd of 500 spectators.

The same team, for the egg-breaking contest, had placed an egg in the buttocks of one member and smashed it with a wine bottle - they subsequently ate the egg. It was reported that the runners-up drank each other’s urine.

One winning member allegedly said, in an interview with The Cherwell, Oxford University's student newspaper: “I think I may have got hypothermia but it was definitely worth it.” Another said: “I sold my dignity for a free holiday.”

While the top three prizes went to teams from Oxford, a Cambridge team, in the eating buckets of snow in a minute contest, were said to have urinated into their buckets in an attempt to receive extra points.

A member from this team lamented: “It was disappointing to make such an effort early on and then not to win. It makes it feel like it was all a bit pointless.”

Other teams posed naked and simulated sex acts to shocked onlookers. One said he thought he saw the participants ‘losing their soul’. Another was surprised at people’s willingness to remove their clothes in the freezing weather.

A video of the event was apparently uploaded onto youtube featuring topless females. A large proportion of the students who had initially signed up for the event were appalled when they saw the nature of the acts, and subsequently dropped out from the contest.

The sponsor was said to be disgusted upon hearing the accounts of the activities performed by contesting teams, claiming that the organisers failed to inform them of the nature of the challenges.

In a statement given to the The Sunday Telegraph, the company announced, "Scott Dunn will be honouring the prize as per our agreement but will have no future involvement in the Varsity Trip and Valley Rally."

They had initially decided to sponsor the Valley Rally in the belief that Oxbridge students would be a “great audience for a high end operator like themselves.”
