A room in the con center is expensive, not something an entry fee would come even close to covering.
We'll need to contact the city to see if they do have a preferred course for relay runs. They may have had events like this in the past. I know the city I live in has 2 routes that they allow relays to use.
Realistically you won't get even close to 1000 people participating in this. At most it might hit 500 but that would be a Good turn out.
If this is not entirely run by ACen it would be run like a panel/live event, with a Host attendee group running it and ACen staff overseeing the more official parts of it.
Sponsors aren't as easy as you'd think to get, it would be extremely challenging to find one who would donate 500 t-shirts even with their name on it (printed t-shirts range from 4-8 dollars depending on how itchy you want it to be). Realistically we could possibly try for a special lanyard saying they participated in it.
If a different organizer chose to run a race during ACen's time in Rosemont that is fine but they couldn't use ACen's name or logo unfortunately. Only those working with the convention would be able to.
We do like this idea, it just wasn't possible for 2013. Space and costs need to be considered and discussed by our management team after this year's convention.
Thanks for the feedback, Bloo! IMO, the event should be about running, not swag/food/drink. It should also have as few barriers to entry as possible, in hopes of allowing even those who only hear about it the night before to participate. While it will be a challenge to organize, I look forward to hearing what comes of future discussions with convention staff!
