I ran this race without training for a PR, and was pleasantly surprised by an 11 minute one!! That being said it was a difficult course, to me. I was not prepared for hills at all and there were a couple. The leaves changing in October in Central Indiana should be enough to bring you to this course. As far as spectators go there aren't many, but that's partly because the course winds through a state park and country roads, it's so worth it though.
