Ultra runner tackles 2,000-mile trek along the Colorado River to sound the alarm on its water crisis

Australian ultramarathon runner Mina Guli is running the entire 2,000-mile length of the Colorado River to spotlight the growing strain on one of the West's most critical water systems. The Thirst Foundation CEO launched the effort as part of her Keep the River Running campaign. Guli told KTAR she set the ambitious goal to show others that if she can take on something this daunting, communities across the basin can come together to reverse the river's decline.
