This post is a few months late but was lingering on my phone from my October 2012 races.  Enjoy!  

Funny signs I remember from the Chicago Marathon:

• May you chafe minimally – yea, Tim, Joanne & Amy!
• I don’t do marathons, but I do marathoners
• Hurry up, the Bears play at 3 PM – I thought this was funny, but I might not have if I was a slower runner.
• the spray painted happy faces on the drainage grates in Boystown

And in San Francisco:

• Hey girl, that fuel belt makes your ass look fantastic
