Looks like you're in for 125k, too. Much better distance for you than me.
I'm not sure why they did what they did other than it looks very streamlined. Thinking that all the 4's and 5's already have options, I bet the total number of 4/5 riders won't be any lower than last year... even if they did eliminate their largest race.
I do have a pretty decent belief that this race won't be in the Illinois Cup, which I find very interesting. If the Cup is going to be mostly in the first part of the year, seems like this might be a great race to have on there.
