This story is BS. Black bears pose no threat unless you represent a risk to cubs. Secondly, I don’t care how fast you are. If a bear is serious about coming after, you’re not going to out run it.

Black bears are very dangerous and they are very fast. I've read they can get up to 40 mph. Nobody's getting away from that.

Lone, predatory black bears responsible for most human attacks
"In particular, the common belief that surprising a mother bear with cubs is the most dangerous kind of black bear encounter is inaccurate," Herrero said. "Instead, lone male black bears hunting people as a potential source of food are a greater cause of deadly maulings and related predatory attempts."

Right, male black bears never attack humans. And these two just wanted a race.

Another unprovoked attack in CO. Camper yanked out of tent by his head. A lone blackie.
