Indiana 100 and 100k Race Info

Summary: The course is a 20 mile loop (approximately 1200 ft/mile of gain per loop), with a mixture of wide and narrow trails, from rolling hills, dirt, and off-camber grass sections, and very little road running. Located in Chain O’Lakes State Park in Albion, Indiana, the terrain and woods provides protection from the wind, and past years have seen rain. Race distances include 100 mile, 100k, and 50 mile options.

Lessons Learned from Race Reports

  • As with most courses, if it rains, expect slick, muddy terrain, especially being a loop course where runners are going over the terrain multiple times
  • Be sure to have a change of clothes for the nighttime loops, especially if it’s been raining, as temps will drop
  • Again, if it’s wet, have changes of shoes and socks and be prepared to fix blisters or the other problems that arise from very wet feet
  • Loop courses have their own special mental tactics – be ready with a plan for mentally getting through 5 laps
  • If it rains, be ready for wading through water, as deep as thigh deep!
  • Be ready with a plan for what you need heading into the start/finish aid station if your crew and/or drop bag is there. That way you have something to think about while running, and you don’t waste too much time at the aid station, and you (hopefully) don’t forget something, like leaving without a headlamp on a loop where it will get dark.
