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.


Black Friday FA50K — For more details please see our Facebook post regarding this event. The Black Friday FA50K will start on 11/23 at 9:00 am EST at the Sand Lake Beach parking lot at Chain O’Lakes State Park. We’ll close our aid stations by 4:00 pm. If you’re on the trails after that time you’ll need to bring a light source.
**Please note that this FA50K is designed for those that are running or volunteering for the GE40 or IT100.


Training Runs — We'll start our Saturday winter training runs in December. Dates are TBD.
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.


Volunteers — The Indiana Trail 100 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


Site Protocol — Our website and Facebook Forum/Event Page is specific to the IT100. Topics discussed include ultra running in general but the focus is primarily on our event as an informational guide to our runners.
Since we are not a generic running site, we do not permit advertisements or solicitations of any kind. This includes, but is not limited to, any running events/sites or their sponsors. We'll remove all material, links, etc., that don’t meet the aforementioned criteria.

Hotel/Camping Options – Below are links to where many of our runners have stayed and will stay for the weekend of the Indiana Trail 100:

There will also be tent camping (non-electrical) available across the street from the start/finish line beginning on Friday before the race. This will be on a first come, first served basis. Electrical campsites in the COL campground will be plentiful for campers or RV’s. The campground is less than ¼ mile from the start/finish line and also has access to showers.
