Fallout

You are a runner, a worker at a secret, reactivated atomic energy research facility near Harwell in Oxfordshire. Suddenly the siren sounds. It is the sum of all fears. There has been an accident. Yes another one, the same happened last year! Radioactive material has been released! It is deadly upon contact, travelling for 40 miles in all directions before the effects lessen. It will take around 12 hours for the fallout to spread that far (approx 3.75mph), getting bigger minute by minute, extinguishing all life in all directions within the growing radius of expansion. You just have time to swallow your iodine pill, giving you 30 minutes to clear the complex and immediate area before the fallout cloud starts to spread, it will expand in real time on the TrackTrail® tracking map. Go any direction you like, but you'll need to stay ahead of the ever-expanding cloud or be instantly vaporized. If you have escaped the fallout for 12 hours you have reached 'minimum safe distance. You'll survive, at least for a few more years... However, the cloud will continue to expand and if you want to live a long, full life, you can keep running until you are the Last One Standing.....
