OK, I've done several marathons--but Sunday is my first century! Husband picked it--so, of course, it is the one with the least amount of information on their website (Ride the Rivers Century, www.trailnet.org/century.php). I think my husband can finish in a pretty good time, but my BIL and I are just wanting to finish (not last). But, we are starting to panic about small details.........

Is there a standard map/cue sheet format? We are trying to figure out if our map holders are the right size (a combination of these two, http://felixwong.com/2002/10/bicycle-map-holders/ and http://www.bicycletouring101.com/Bik...eMapHolder.htm). We've ridden most of the route, but not all of it--especially downtown.

Is lunch standard? What should we expect at the stops? I am bringing my usual snacks: jelly beans, cytomax, gu and clif bars--but I usually need some solid food at some point--guess I can swing through McDonalds--can you go through the drive-thru on a bike?

You probably can't answer this, because every ride is different, but--how many people will be at this thing? Will it be crowded? Will we get left behind and get lost? (local biking forum is not help--apparently this is all supposed to be a secret to newbies).

We are both pretty strong riders, but are still panicking and willing to bail into the SAG wagon without losing too much pride--but this is the last century of the season here, and we'll have to wait until next spring to do another century. Any advice (even on things we aren't panicking about yet) would be great!
