  • All clothing will be brought back to the finish line area at the finsih line at the high school and placed in a designated area for each race. You may also leave articles of clothing with the aid station volunteers, and everything will be returned to the finish line area. Many runners use that option with their articles of clothing as it is always quite cold starting out, and warming up as the race progresses. There will be a drop off point/vehicle at the start of both races.

  • Crew and Supporters be aware that there is considerable traffic on Highway 47 and the road is narrow—be very conscience of other traffic. Pull out only where there is sufficient room to do so.

  • Marathon, Half, Relay: We award a 1st, 2nd, and 3rd place finishing plaque, in 10 year age categories, in the Full Marathon, and the Half Marathon, Men and Women divisions.The age group breakdown goes as follows, 19 and under, 20 to 29, 30 to 39, and so on. We also award four Masters runners, one for each race. That being said, we won't double dip on winners. The first place finisher in either race, or gender,  regardless of age, is the overall winner, and will be awarded the first place trophy. If they happen to be a masters age runner, then the Masters plaque would then go to the second runner over forty in either race or gender. If the masters runner does happen to finish in the top three of his age group, the next three finishing runners would then be awarded 1st, 2nd, and 3rd. That also holds true for our four overall winners. Whatever age group they are in, they receive the overall winner plaque, and the next three finishers are awarded 1st, 2nd, and 3rd. We appreciate all of our runners, and want to award as many of them as possible for their effort.
  • All runners must be registered. Runners without an official number will not be permitted to participate in the race.

  • Refreshments including food and drinks will be provided in a specially marked area for runners only.
  • Kiosks will be set up near the finish line that have instant results, so a runner can find their time, and finish order, simply by typing in their bib number. Also, on each bib there is a QR Code, that when scanned by a smart phone or tablet, will also give the runner his/her results. We do not do an official awards ceremony.  Awards will be available as soon as results are verified, and can be picked up from a table near the finish line. One of our volunteers will assist you. Many of our runners need to leave for long drives, and or airline flights, or are anxious to head on to Yellowstone Park, so we like to get them one their way.
  • Official results will be available on our web site as soon as possible following the race (hopefully within 24 hours). Results will not be mailed unless specifically requested.
  • Bibs can be transferred, and runners can switch races, but only on approval from the race director, and or a Vector Timing official. This can happen on race day at packet pickup, but must be done prior to boarding the buses to head to the starting line. No switching will be allowed  once the race officially starts.
  • The race committee reserves the right to cancel the race for reasons that it deems appropriate. In the event the race is canceled, every effort will be made to contact all entered runners as soon as possible.
