The London Marathon is this weekend, and as always, the city’s streets will be packed with thousands of runners and of course the odd eight-foot chicken.

But if all that sounds like too much hard work, but you still fancy yourself as a bit of an urban athlete, this could be just the ticket.

The Nike Grid is challenge to see who can get from point to point in London the quickest. You choose a postcode and then you have to start at a special phone box. You then have to get to another phone box in the quickest time – on foot.

You can do as many stages as you want and there are prizes for the champions.

On your marks…
