IMHO lots of people turn a false charge into the real thing, by turning tail and running.You know those rubber balls dogs love to chase ( a red one for my lab) well you've just become the equivilent for a black bear. Stand your ground, you won't win this footrace.
Our last bear attack in this area, a young tree planter fought off a young bear with a garden rake. She got some minor bites to her hands ( and a story for the grandkids)
. Bears are used to being the neighbourhood bully hit them hard if they are right at you.
Anyway my bear tale ( I have a few ) is
Camping 2 years ago, in a provincial park. My 9 year old daughter had to go to the bathroom real bad. It was located about 200 yrds from our site. Anyway she leaves, comes back too soon. Did you go to the bathroom? Nope. Forlorn looking head held low
Why not? Bear won't let me. Went with her, a yearling eating a can of beans some fool just threw on the path. Yelled and waved him off,and he went to my site where our dog treed him. We went for a walk and 1 hour later, he was gone to where ever it is bears go when they want to be away from the scary people. My daughter had walked up to withen 10 yrds of this bear before seeing it and walked slowly back looking at it, until she was back near us. Pretty proud of her
Take Care
