Run 2 laps for 50 miles, 4 laps for 100 miles, and 6 laps for 150 miles on Chain O' Lakes State Park's 25-mile loop course.
The Indiana Trail 100 is an ultra trail race held at Chain O Lakes State Park in Albion, Indiana, USA.
It is a non-profit event run by ultra runners, with net proceeds going back to the park providing course.
The organizers explain that there are many ultra runners among the volunteers supporting the participants.
It is a competition that connects people running long distances with activities that maintain the park.
Course is a structure that repeats a 25-mile park loop.
50 miles covers two laps, 100 miles covers four laps, and the newly added 150 miles covers the same loop six times.
Rather than traveling to distant finals, participants return to the same park over and over again.
The number of repetitions increases depending on the event, so meeting the same path again is a basic condition of the race.
The topography of Chain O Lakes was formed by the action of glaciers.
The park management agency describes the region as featuring interconnected lakes, rolling hills with forests, wetlands and valleys.
This forest path in the lake area forms the background for the competition.
The Ignite Trail Series was started by local runners as a way to give back to the parks they used to run in,
using the profits to purchase trail maintenance equipment and add new trails.
Part of the series is the Indiana Trail 100, a long-distance event that organizers present as a Western States qualifying event.
