Great news! That either means that the runners will have a new record running time -
Or, the wild Canadian Black Bear eats really well in time for winter.
Win-win.

Some runners are more photogenic than others.
Well you pull out your Ruger Blackhawk in .44 magnum and shoot the bear. Never leave home without it!
So?
A black bear, unless it is a sow with cubs —and you get between her and her cubs — is much less dangerous than a grizzly bear. Usually you wouldn’t even know it was there, as it would try to avoid humans. It is when they become used to humans, often by feeding out of human garbage, that black bears become dangerous.
Stupid hikers probably had energy bars in their pockets.
That bear was trying to get them off his property
The bear was partly scared as evidenced by climbing the trees, but it acted like it was expecting a handout of some food from the runners. The runners were smart to not actually try and out run the bear. It might have provoked a chase response.
Anybody moving in bear country should be armed and know how to use their weapon of choice.
Were the runners clothed or running bare? (from the bear)
What did they expect roaming around in the bears’ backyard?
You sure it wasnt two hikers who encountered a bear while running?
That bear seemed like he was looking for food (like previous runners / hikers had fed him).
What a couple of wimps. That was a juvenile bear and he was showing no signs of aggression. He just wanted food.

I never go out into nature without a firearm. It’s just common sense.
Looks like they did the right thing. When Yogi was close, they backed up and maintained eye (camera) contact and made lots of noise. When Yogi seemed to lose interest, then broke contact for shelter. Next to armed defense (.357 for a black bear), they seemed to do everything right.
Black bears matter.
So, which jogger was faster?
Never leave your home without your officially approved bear spray (or aka bear condiment in some circles).
