Said it before and I'll say it again: I've never met someone who's a competitive or serious or lifelong runner who is concerned with being seen by others as a 'runner'. It's Dave from accounting who used to be in shape in high school and could get back in shape if he wanted to, that why he started run/walking last week, he's the one who cares if you see him as a 'runner'.
It's the same here. Completing a marathon is really cool. Someone who completes one so they can be athletic-in-name-only for the rest of their life is probably more concerned about the definition of 'running' than the group going for a new PR, regardless of their relative paces.
