Marysville, VIC
Unbreakable is inspired by the legendary Barkley Marathons, widely regarded as the hardest ultramarathon in the USA, if not the world. Conceived by the legendary Gary Cantrell (aka Lazarus Lake), the race was inspired by the 1977 prison escape of James Earl Ray from Brushy Mountain State Penitentiary. Ray managed just 13km in 55 hours through Frozen Head State Park. Laz famously said he could’ve done 100 miles in that time. And so the Barkley was born, named after his neighbour and friend Barry Barkley. The French answered with Chartreuse Terminorum. And here in Australia… We created UNBREAKABLE 🇦🇺🔥
