Urban Attack, it's a sprint but harder than a marathon...

The original knock out obstacle racing series and the biggest indoor racing out there to boot.

Racing inside iconic sporting venues with a roaring crowd, turning participants into 500 modern day OCR gladiators performing in front of live TV cameras in the electric atmosphere.

Multiple races throughout the day, racing head to head - battling, jumping, running, swinging, crawling, sprinting, climbing and dragging over a mass of obstacles packed into a 1 km indoor course.

Race your mates, to win or just for the hell of it - whatever reason, you'll become part of a special breed. 2015 sees the development of full live online TV broadcasting with re-runs of the key races freely available to view anywhere in the world.
