There's an elevation graph on the Hillyhundred.org site. Tabor Hill is NE of Stinesville, just before the Sunday lunch stop. Looking at Google Earth, N Mt Tabor Rd rises about 131ft in 0.31mi. (To where the route turns onto W Tabor Hill Rd). The steeper section near the top rises 54ft in 0.14mi. Wouldn't be so bad if it weren't crowded with cyclists, many of them struggling, and that there is often auto traffic to contend with, too.
Southern Indiana is much hillier than the flatlands of Central Indiana. No real elevation, just lots of steep.
