Andrew, agreed. I also used to like record assaults. The more I watch races, though, the more I realize a record assault is kind of boring. It's just watching one person run usually solo at a fast pace and checking splits when possible. Take a race without rabbits and with a reasonably well matched field and you have a lot of drama unfolding.
NYCM has been wonderful without rabbits. It would be nice to see London, Chicago, Berlin, etc. follow suit but I think the events with courses that are potentially record courses are not at all likely to give up the record assaults. For NYCM, records weren't likely in the first place.
