Runners World people are joggers who run all of their runs at a 13 min pace, and Lets Run people all think that they know everything because they were pretty good in high school (in the 15's or 16's)...
Runners World people dont worry about people cheating. Lets Run people HATE cheating.
Runners World people are not actually runners. Lets Run people WERE actually runners, but now they are just know-it-alls that live in their parents basements.
Runners World people are losers. Lets Run people are losers.
