Race Across The World star Sam Gardiner's cause of death has been revealed. The 24-year-old, who competed in the BBC One series alongside his mother Jo, died in a horror car crash last month. An inquest heard the former candidate of the BBC One show died of a 'devastating brain injury' after the horror collision on the A34 in Stockport. He lost control of the car after it hit a kerb on a central reservation on May 26. The vehicle rolled and ended up on its side, as confirmed by Greater Manchester Police. The landscape gardener sadly died on May 29 from his injuries. In a poignant statement previously released by his bereft parents Jo and Andrew, they conveyed their overwhelming grief, expressing that they were "devastated" over the loss of their "special" son. Their heartfelt words described how: "We are devastated by the loss of our beloved son Sam in a terrible accident. Sam left us far too soon, and while words will never fully capture the light, joy and energy he brought into our lives, we hold on to the memories that made him so special." It continued: "He was willing to go wherever the trail might lead and he touched everyone he met on the road. He found great happiness working as a landscape gardener on the west coast of Scotland. "Sam brought warmth, laughter and a smattering of chaos wherever he went. He leaves behind a huge hole in our hearts. We will miss him endlessly, but we'll also remember him with smiles, tall tales, and a depth of love that will never fade". Sam succumbed to his injuries a few days after the crash, as a spokesperson from the Greater Manchester Police reported: "We sadly must confirm that the driver of a white VW Golf R estate involved in a single vehicle collision on Monday 26 May on the A34 in Gatley has since passed away from his injuries. "The driver, a 24 year old man, has been identified as Sam Gardiner. His family have been notified and are receiving support from specially trained officers. They have requested privacy during this dreadful time. We'd like to express our gratitude to everyone who shared our appeal and sent their best wishes to Sam and his family." A spokesperson for Race Across the World said: "Everyone who worked with him and indeed everyone who watched Sam could see just how valuable and transformative the journey was for both him and his mum, Jo. "Sam embraced the seven-week trip with an energy, love and a determination that saw the pair enjoy adventures across Mexico to Argentina making audiences fall in love with them and their special bond as a result. "Since filming, both Sam and Jo have been an integral part of the Race Across the World cast family and on behalf of us all from the BBC, production and the rest of the cast, we would like to extend our deepest condolences to his parents, Andrew and Jo; his brothers."
