About the Race
In the 1980's the Park Forest Running and Pancake Club held their annual progressive marathon by adding up four separate "races" with the Park Forest Scenic 10 to have a Marathon time.

Common questions
How hard is the IPTT Progressive Marathon Marathon?
We don't have a verified elevation profile yet — check the organizer's course map for the climb breakdown.
What should I wear?
Dress for ~10°F warmer than the standing temperature once you start running. Throwaway long-sleeve at the start, gloves and a hat for sub-50°F mornings, singlet plus visor when it climbs above 60°F. The race-day forecast above is the source of truth closer to the date.
When does it sell out?
No published deadline. Most races raise the entry fee in tiers and can sell out without warning — sign up early if you're committed.
