Another important thing in the email is updating proof of time. The last day to email a change is July 1st, but you can also update it at the expo (although changes at the expo discontinue in 2014).
Even little emails like this keep me motivated and build anticipation for the race. But it also reminds me that I need to figure out our costumes! It's coming up fast!
Do you get excited about a race months in advance? How do you prepare?
