Race discount codes

I was looking at the Race Program for the Houston Marathon and saw a couple of ads for future races elsewhere.  As much as races cost, I thought if we would look through the race programs for the different locations for the discounts and its expiration date, we might be able to save a buck or two.

So, here are three I spotted:
CIM, $15 discount, "Houston15", expires January 30
San Antonio Rock 'n Roll Half or Full, $10 discount, "Houston2015", expires February 28
Dallas Rock 'n Roll Half, $10 discount, "Houston2015",expires February 28.

thanks for posting.  I may want to do CIM next year, but won't commit this early to save the $$ unfortunately.

If you register today (1/27) the Miami Marathon is only $70 for the full and $57.50 for the half.
