Also. Never Run. Please don't listen to this person.
If you run, in any mammal will trigger to catch you. (Bear example, or dog catching tire of car).
Yeah, right. I had a dog get run over chasing car tires. That's the whole point of running. You get to choose the terms of combat if pursued.
Sun Tzu's take on martial combat:
"When ten to one, surround them"
"When five to one, attack them"
"When two to one, do battle with them"
"When matched, divide them"
"When insufficient, avoid them"
The same rules that apply to commanding armies apply to individual combat and if retreating to a more suitable location or disappearing into a crowd are not options and you are not willing to yield groud then at some point, defeat is almost assured.
Real life is not some martial arts demo with accomplises clumsily flailing at you with rubber knives:

Keep it real. Listen to "this person", OP. Aikido won't stop a bullet!
