Colorado marathon runners had an extra incentive to chase a PB this weekend after a black bear wandered onto the off-road trail interrupting the race.
Photographs from the event shows the bear crossing paths with participants in the Leadville Trail Marathon on Saturday, but thankfully appeared uninterested in the runners.
Quentin Genke caught pictures of the bear and shared them on Facebook, telling social media that the bear popped out at around the 12.5-mile mark.
