Ultramarathon burns survivor Turia Pitt has won a multimillion-dollar settlement against the organisers of the race that left her with burns to 64 per cent of her body.

Ms Pitt and fellow competitor Kate Sanderson suffered life-threatening injuries in the race in September 2011, while running through WA’s Kimberley region as part of the event organised by Racing the Planet.

Both women suffered burns to at least 60 per cent of their bodies when they became trapped by the fire on the course near Kununurra.

Ms Pitt suffered burns to 64 per cent of her body, and had four fingers from her left hand and her right thumb amputated.
