London Stag vs Hen GPS Challenge

Only available in London, the Stag vs Hen GPS Challenge runs every Saturday from April-September. Get a team together and race round the capital, conquering hilarious tablet-based challenges, taking photos, recording video clips and answering questions in a nail-biting race against time. Will you walk away winners or be beaten by a load of girls?

The aim of the game is to complete as many challenges as possible, which revolve around some of London's most famous landmarks. Challenges mean points and what do points mean? That's rights folks; prizes!

The London Stag vs Hen GPS Challenge starts in the time-honoured tradition: in a pub. When all the teams have arrived and everyone's necked a cheeky pint, the event manager will do the briefing bit, get the banter going and hand out team packs. After that, it's straight into the main event.

When the time's up, leg it back to the pub for pints, results and presentation of prizes and medals. Prizes will be awarded for best video and best images, with medals for the overall winning team. You'll also get offers on drinks at the pub if you hit the magic number of points.

No one needs to be Bear Grylls to get involved. Team spirit and a smartphone or tablet is all you need to take part in the London Stag vs Hen GPS Challenge.
