Sometimes we choose our challenges. And, sometimes, challenges choose us. What we decide to do about them is what counts.

Mark's story set for cinematic release.

Just as the brake lights of rush-hour traffic began to dwindle last night, thousands more red bulbs suddenly lit up the centres of three Irish cities as thousands of runners took to the streets for a run in the dark.

On November 13, as darkness falls, thousands of people will run through Dublin, Belfast Cork, London and Manchester to raise money so that one day the paralysed might walk.

As darkness falls on Wednesday, November 13, thousands will gather, pull on their trainers and begin running in the hope of playing a part in improving the lives of paralysed people across the globe.

Blind and paralysed from the waist down, adventurer Mark Pollock continues to defy the odds by walking in a pioneering bionic suit.
