I don't know that I've seen an "official" elevation profile, but I can help you piece together the route using the elevation profiles for the area, found at

http://www.srcc.com/cgi_bin/profiles.pl

The early climbs are (in route order) Graton Rd, Coleman Valley (only if you're doing the 200K), Mays Canyon and Green Valley. The last climb is Chalk Hill, which isn't all that bad, but it is at the very end.
