The 2009 Trespass snowboard-cross podium has to take evasive action as they are pelted by snowballs during the presentation ceremony.

Winner James Foster (centre) prepares to hit back and third place Nick Dudar's snowboard comes in very handy to thwart the attack.

Foster won his first British title in Les Deux Alpes, in France, in 2003 and now competes on the world stage.

His sister Kate is also a top rider and she finished runner-up to Lesley McKenna in the half-pipe.
