I received this email from the Chicago Marathon organizers:
Registration for the 2014 Bank of America Chicago Marathon has been postponed until March 19 at 12 p.m. Central Time to finalize a routine yet comprehensive assessment of our new registration process. We apologize for this inconvenience and thank you for your patience and understanding as we aim to ensure a seamless registration experience for all who wish to register for the event.
Thumbs up for beta-testing! Is this a lesson from the ACA experience?
Last I heard, this October race was tentatively on a few calendars. I'm not going to enter, but I might enjoy cheering and pacing if there is a good excuse for doing so.
