Is it bad that during any chase I always lose?

I mean even when I am running away from someone that person can catch me easily as I am slow in running and also when I am chasing someone I can't catch him. It has happened few times in school when I used to run away from senior boys when I was in 10th and 11th grade and they could catch me easily. Similarly I used to chase many too if they messed with me but I could never catch them
