Tiger 10 Miler - 3rd Annual Trail Race

Tiger 10 Miler Covid-19 Updates (7/7/20):

We are excited to move forward with our race on September 19th 2020. We have been reviewing each phase of the restore Illinois Plan to make sure we can safely hold the race. At this time not knowing what the future holds we are putting in a few changes this year assuming we will still be in Phase #4 at the time of this year's race. If state guidelines change, we will adapt our race policies to make sure we are in compliance.

Changes/Updates as of July 7th:

  • We will be creating heats to limit the amount of runners starting the race at a given time. We are currently limiting each heat to approximately 40 runners.
  • You can request to be in the same heat as another runner. We will do our best to accommodate requests.
  • Heats grouped based on your approximate finish time answer.
  • We will notify everyone as to what heat they are in prior to race day.
  • Approximate heat starting times:
    • 7:30AM- All Walkers
    • 8AM- Heat A
    • 8:10AM- Heat B
    • 8:20AM- Heat C
    • 8:30AM- Heat D
  • Runners will have 3 hours to complete the race beginning at their heat start time.
  • We will provide emergency water stations only. Runners should bring their own water for race day.

Join us for the third annual Tiger 10 Miler Trail Race and after party! This exciting race will take runners on ten miles of twists, turns, and hills within the Byron Forest Preserve and the more secluded Nardi Equine Prairie. All participants will receive a custom finisher's medal, shirt and our unique age group awards go 3 deep in 5-year brackets. Overall male & female winners and also male and female masters winners will receive awards and a cash prize. Special awards will be given starting in 2022 for five year finishers of the Tiger 10 Miler. Those five years don't have to be consecutive, just five total finishers. This is a "cup free" race so please bring your handheld water bottle or hydration pack as we won't have paper cups at our three aid stations in order to keep our trails clean and be environmentally friendly.
