Well Duh.......
Baggy grey tee shirt, cheap baggy shorts, unclear brand of nondescript trainers and doesn't look like he has a GPS watch, no lycra in sight, no flouro colours........what other evidence do you need FFS ??
Probably never even heard of Strava, Gu Gels or SCaps either and has no idea what a Michigan or Reducing Ladder session looks like.
Baggy shirts, baggy shorts to around my knees, never worn lycra, no idea what Gu Gels, SCaps. Michigan or Reducing Ladder sessions are: you've just described me.
I wouldn't call myself a runner though. In fact, currently, I aspire to "jogger' status!
