I'm running my first 5k on the 31st/1st (R.I.T.N.Y. Run), and plan on buying a shirt to wear specifically for this event.
Here are the two I've narrowed it down to:
Both images will be on the back of the shirt only.
The 'doctor' shirt has a slight advantage because I could wear it when I'm not in a race. The other won has an advantage because it's clearly going to piss people off and compel them to run faster.
Which would piss you off more if you saw it on a fat runner ahead of you? Which would give you the bigger laugh?
