As a Coach/Runner I follow many other Coaches,Pro runners and College athletes on Twitter.
Some are funny, interesting, informative, while some are repetitive and uninteresting.
Here are my picks:
BEST PRO- Matt Centrowitz
BEST COACH- ? Suggestions?
Best College- Blake Theroux
Don't mean to be rude, but....
Worst PRO- Leo Manzano
Worst Coach-Steve Magness
Worst College- Too many to name just one
