Welcome Ultra Runners!


We’ve made the decision to suspend registration for the Indiana Trail 100, effective immediately, due to COVID-19. Please note that this is not necessarily a precursor to cancellation. In terms of race planning, it’s business as usual for us right now.

The reason for the registration freeze is twofold:

  1. Per the advice of local officials, it will be a couple more months before we better understand the direction that health and safety conditions are headed. We’ll take that time to form our mitigation plan with medical experts, as well as continue our ongoing dialogue with the various local and state agencies involved in the decision-making process.
  2. It’s important for us to balance the needs of this year’s event with next year’s event. What that means is that we don’t want to overload registration now until we learn more. If we have to cancel and shift everyone into next year’s event, we still want to have plenty of spots available for 2021 registration.

In lieu of registration, we have enabled our waiting list for all distances. This will allow runners to reserve their place in line if we’re allowed to proceed while not charging them a registration fee. If it’s decided later that it’s safe to continue, those at the front of the line will be invited first to register. It will continue in descending order until we reach capacity.

Due to the registration freeze, we’ll push back the next price increase from 7/31 to 8/31. We’ll keep you informed of any further developments. Please note that it’s premature to comment on cancellation options. We’ll have that discussion when it becomes clearer to us that the event cannot take place.

If we move forward, we’ll share our mitigation plan with you, as it will require your complete and utmost understanding and cooperation. The amount of potential changes required within the plan to even contemplate having a race could be extraordinary and would make this a much different race than past years.

This is an unprecedented time and we appreciate your patience and understanding, as we all navigate this situation together. Please know that whatever is decided, the health and welfare of the participants, volunteers, and crew will be our top priority. If you have any questions please contact me at
