The prize includes four return economy flights from London to Wyoming, four nights’ accommodation at a working cattle ranch in the stunning Shell Valley and three nights’ accommodation in a remote mountain cabin. The winner and his or friends will receive intensive riding training as well as learning rope-work, cattle-reading, survival skills and fishing, and will take part in a real cattle drive across country.

The holiday dates are set (18th July 2009 – 25th July 2009), and you and the friends that you choose to accompany you must be aged between 18 and 64 and weigh less than 16 stone, due to the nature of the activities included on the trip.

You can enter the competition via the Lucozade Challenge website – you will need to confirm the details of the friends that you want to travel with, and will need their permission before supplying these details. Entries must be received by midnight on 9 July 2009.

Full terms and conditions, together with an itinerary, can be found on the Lucozade Challenge website.
