Trail pup Nelly hits the single track at 12,000 ft above sea level during a long run in the high county of Leadville, Colorado with her owner

More: Nelly is an “ultra pup”. Not because she’s ran an ultramarathon race, but because she does all the miles in training with her owner. When she’s not snoozing the day away on the couch, she’s out there running with her human.
