Battersea power station is the venue for the London Freeze snow sports and music festival taking place at the end of the month – for a long weekend the building will be transformed into a giant indoor ski resort featuring bars, music and some extreme snow sports like the UK leg of the LG Snowboard world cup. Or, if you like your sports more virtual you can try your hand at the new Sean White snowboarding game on the Wii.

We’re giving away a pair of tickets to the event and all you have to do is answer this simple question:

How many meters long is the ski run? (hint)

Send your answers to [email protected] – we’ll be pulling names out of a hat at 6PM next Wednesday (14th October).

Good luck!
