Welcome to Hindsight Ultra Trail Runs, a local grassroots race that looks easy on paper, but can catch up to you in a hurry. While the race does not have a lot of vert, it makes up for it with varying terrain, some technical trails, and a long stretch of exposure. While we have sign-up and formal finish times/results, we will do our best to maintain the grassroots feel to the event. This is a great event for any runners looking to complete their first Ultra distance, complete the next distance on their list, or want to train for the next ‘A’ race.
The start line is located behind the Dixon Park District Facility in Dixon IL. It is a 7.85ish mile loop. 2 loops will get you a 25k, 4 loops will get you a 50k, 8 loops a 100k, and 13 loops get you 103 (3 extra credit) miles. The course is a blend of everything except water crossings and mountains. Roughly 50% singletrack, 30% grassy meadows path, and 20% gravel path. Total elevation for the 100 mile is roughly 6200’ which calculates to just under 60’/mile. While the course is maintained, expect there to be tree roots, small tree stumps, some rocks, ankle rollers, and anything else you would expect to be on a singletrack course.
There are 2 aid stations; Start/Finish (S/F) and a water station that is at mile 3.7ish. At S/F, there will be water, snacks, hot food options through the night, plus anything that volunteers and runners might bring to share. At the 3.7ish mile water station, we only provide water and ice. We allow crew at S/F and at the aid station. The aid station is only a 1/3 mile walk from S/F. Pacers are allowed after the first lap for all distances and can join/leave the runner at the S/F and aid station. Personal canopies are allowed, spots are first come first serve. No campers. Set-up begins at 5am Saturday and packet pick-up begins at 5:30am Saturday.
We hand out medals to all 25k, 50k, and 100k finishers. 100 mile finishers will receive a buckle. New for this year will be awards for the top 3 male and female finishers in all distances. You must start at the designated start time to be eligible for the top awards.
Hindsight 100 takes place on Dixon Park District property. Please respect the park property and its visitors. The park is open during our event and we need to be kind and courteous to other park visitors. You must follow Park District Rules. RUNNERS: You are responsible for you and your crew while on Park Property. Anyone caught disrespecting Park property and or event staff will be removed and the runner will be DQ’d and will receive a DNF. While this is a ‘grassroots’ event, we do not want to jeopardize our ability to host this event in the future.
Embrace the challenge and enjoy your run!
