Nike GRID explained. Mostly.

The official info on the Nike GRID game...

Curious to find out how they're going to score and track all the runners, plus prevent cheating. I guess there could be a minimum time set between each phonebox, then if you clock in at a faster time you're obviously cheating. Like if you're claiming to have run between 2 checkpoints faster than Usain Bolt at his best, you've obviously hopped a ride on your cycle or jumped the night bus.

Let us know if you're going to play, we want to hear how it goes!
