Should be on Livstrong.org, if it's not up yet they havent determined the route. If its anything like its been in the past, bring your climing legs. I rode 2 & 3 years ago and there were quite a few people complaining about the climbs, but it's a nice loop. Go get em'!
I live TN and I am planning on attending as well. I have not seen the actual mapmyride 2009 map yet, but my understanding from a friend it is the same as the 2007/2008 maps on here. in the way of climbing i believe it is 4600+ft of climbing (i believe that is what the LS website stated.)
yeah it's real hilly for sure, I didn't find it very enjoyable. It felt like it was just climb after climb, I haven't done the Livestrong in 2 years I've done the Philly ACS ride which is a nicer course the 65 mile ACS route seems less tiring than even doing the 40 mile Livestrong route...hopefully they've changed it, I did it in '07
