For those looking to experience Mt. Lemmon along with a few thousand others, 2010 will hold the inaugural Marathon run up the paved road... but more likely this is just to give notice of what to avoid that weekend in October... they are allowing cutoff times that would make it fairly easy to finish their event at a brisk walking pace, and unlike some of the other more difficult marathons, there is no qualifying. It would be sort of fun to see some fit hikers scoot up to the top ahead of the "normal" marathon runners!
