QOTD: Since Disney is changing the way they do registration with delaying opening it up for marathon weekend I believe for security reasons maybe... If it was up to you, what other things would you change if you could?
First off, I think RunDisney is making a mistake by introducing a new registration process/system for their hallmark running event. They are exposing themselves and the participants to risks and fallout with the new implementation. If I were them I would have scheduled an implementation for a smaller race event where the exposure is less than the marathon weekend exposure. I'll step down from my soapbox now.
Things I would change if I could? 1/2 marathon course for marathon weekend. Move the start times back to 6:00 AM or 6:30 AM. I understand the impacts on parks, traffic, etc. but it could be done. Reward the finishers with a "real" post race celebration, similar to the Pleasure Island free admission back in the day of Marathon Weekend.
