The deets:
The Indiana Monumental Marathon (and half, and 5K) or "The Monumental", as it's affectionally known by locals, is maybe one of the all-around best races I've ever participated in. Clearly runners in the Indiana area are aware of its charms, but I can't really speak for how well-known it is beyond that. Despite it being one of the 15 biggest marathons in the country, my West Coast self had never heard of it before I started researching smoking fast half marathon courses.
What makes this race so great in my opinion?
