A stunning walk along some of Indy's downtown. Runs along the Eiteljorg History museum, the Indiana Historical society, the Indiana State Museum, the NCAA Hall of Champions and ends next door to the Indianapolis Zoo. Will give you some of the most beautiful views of the city.
Indy 500. If you are a fan of racing, this is Mecca. Or at least something like that. I've run the Indy Mini Marathon two years in a row now and have had the pleasure of kissing those bricks after starting the race with a high five from Tony Dungy. But for non-race (cars and marathons alike) days, there's a racing museum next door as well.
