Clearly, there are things a runner does, intentionally or not, that disrupt team cohesion. And there are also things a runner doesn't do that can cause problems: not trying, showing up late, skipping team-building activities, and ignoring the coach's instructions.

Showing up is not all of life - but it counts for a lot.

To stay on the map you've got to keep showing up.

The issue is, you're not going to have a lot of inflation showing up when you have no velocity.

Whether you like me or you don't, I still dig showing up for work.

Cheer for your teammates, regardless of whether they're fast or slow, veteran or neophyte, varsity or JV. Or rally the spirits of someone who's had a bad performance. Also, encourage stragglers during tough workouts; jog back to 'pick up' a runner who's behind during a long run.
