Welcome Ultra Runners!



2019 Race Date — The 2019 Indiana Trail 100 (IT100) will take place at Chain O’Lakes State Park (COL) on October 12-13, 2019. Please save these dates to be a part of our event. The Indiana Trail 100 features a 100 mile, 100k, and 50 mile run.


Cap — The cap for the 2019 Indiana Trail 100 is 400 total runners. It is at the race committee’s discretion to determine the field size for the 100 mile, 100k, and 50 mile runs, respectively. We’ll provide advanced notice if we decide to increase, decrease, or close down any of the fields. It is your responsibility to register before we reach our cap.


Waiting List — As soon as the 2019 Indiana Trail 100 reaches its limit of 400 runners we’ll implement a waiting list. The runners will be placed on the waiting list in the order they sign up; the first on the waiting list will be the first to take the place of someone that drops out.


No Deferrals/No Refunds/No Transfers — There are no deferrals, no refunds, and no transfers for any reason, including injury. However, we’ll allow runners to switch from the 100 miler to the 100k or 50 miler, and vice versa, after you have signed up. Please note that you cannot switch races on race day.


Qualifiers — The Indiana Trail 100 is a UTMB and Western States qualifier.


Training Runs — The March training run dates are 3/2 and 3/16.
The group will run one loop (20 miles) but some runners will go further and some less. Please note that we’ll use the GE40 course in the winter and it will go in the opposite direction of the IT100 course. The Saturday winter training runs are a good way for runners considering the GE40 and IT100 to check out the course and discuss strategy with several local ultra runners. We typically see runners from all over the Midwest during these runs.
Please note that some of the designated training runs will have rolling aid stations. But plan on being self-sufficient and have backup hydration/nutrition with you while running.


FA50K — The tentative date is 3/30. If trail conditions are subpar we’ll move it to 4/6.
The group will run up to 31 miles but some runners will go less. We'll use the GE40 course and have rolling aid stations available as a courtesy to our runners and volunteers preparing for the race. A group invite was sent out prior to this note.


Trail Maintenance Day — 4/13 (Two weeks before the GE40). A group invite will be sent out shortly. It's a great opportunity for our runners to give back and clean up the course that they’ll be running on for the race.


Volunteers — The IT100 is known nationally for its volunteers. For information on how you can you can join our team as a volunteer please contact Steve Carr at
