Yeah, most people are pre-registered on Eventor
. And we had a lot of people helping out with all aspects (about 25 - still over 100 people from my club were able to race). Registration on-site is relatively simple since most people do not pay then -- their clubs are billed for everyone in the club after the event and then each person pays at the end of year (most likely), one big payment for all registrations for the year. (This is, by the way, a really awesome way to do things.) We still had a dedicated and busy team of people doing data entry (entering new registrations, changing brick numbers, handling mispunches) the whole time:
The more impressive part might be starting 586 people in a one hour window. Three similar length courses, so that's three people starting at once, with a start interval of 15s. The beauty of this system is that there's still room for more people!
