It wasnt funny what happened to her,lot of differences,weight 120 pregnant,attacker 190 strangled her,after the run on the walk back to her car meeting him as he was a walker as well on or by the road which normally has some traffic.He was looney bins,not a normal robber etc.
Change your running schedule to include when people are normally present,and should one member quit all quit,her sister kept on running ,to which most likly will forever haunt her.
If you feel you must pack while running the light plastic 6 oz-10 oz pistols fit the bill many have a clip p3 coming to mind or small holster with a retention strap.
She put up a fight had she much of anything pepper spray etc but while running you tend not to carry much ie added weight.
Had the sister shown some care stopped as well walked back with her,doubt if he would have attacked two women.
But finishing her run was more important than her pregnant sister.If I seem harsh,it is because those that have take for granted,I have no brothers or sisters and surely would give to them what we would give freely to a stranger in need.
In her case it wasnt so much she didnt have a gun but became isolated,of her own doing but avoidable and ran into a whaco.
