The 100 mile and 100 kilometer races will follow a well-marked ~20mi course that starts and finishes in Louis Murphy Park but spends most of its miles in the Mines of Spain Recreation Area on the expansive network of dirt, grass and rock trails that run throughout. Each loop contains a couple of short stretches of pavement, primarily at the beginning and end, to help connect the different segments of the course. Runners will be treated to beautiful views of the Mighty Mississippi River from a number of stunning vantage points, a tour through and around the iconic Horseshoe Bluff as well as panoramic vistas of beautiful grass prairies and dense hardwood forests. The trails range from steep & technical to flat dirt single track to rolling & grassy and everything in between. While there are plenty of hills to challenge you at the Mines, there are also ample stretches of trail where you can really open up and find your stride. This is a truly diverse course that is perfect for your 1st hundred or your 100th hundred!

A unique part of our race is that crews are only allowed at the Start/Finish with runners being able to see their crews every ~20mi. This means crews are able to set up, stay put and don’t have to drive all over during the race! Crews will be able to set up space in Crew-ville which is adjacent to the Start/Finish line aid station and then attend to their runners either in Crew-ville or at the aid station when the runner returns after each loop.
On Friday, we will have food brought in for crews that will be included in your runner’s registration and on Saturday a food vendor will be on site beginning early in the AM and going through the post-race finish and awards.
To reiterate, crews and pacers are ONLY allowed at the start/finish aid station at Louis Murphy Park. There are no exceptions to this rule and any crews that break this rule subject their runner to disqualification.

Pacers are allowed for the 100mi after 3 loops (or 7pm) and for the 100k after 2 loops.
Only one pacer is allowed at a time and only from the Start/Finish.

There are 4 aid stations that you pass through a total of 5 times per loop. There are 3 on course as well as Crew-ville at the start/finish. The furthest distance between aid stations is 6.3mi and the shortest stretch is 2.1mi. Crews are ONLY allowed at the start/finish aid station. Any runners receiving aid from crew anywhere other than the start/finish aid station may result in disqualification.

Drop bag service is provided at ALL 4 aid stations. Drop bags must be labeled with bib # and name of aid station and dropped off at Thursday night packet pickup or at the designated area at the race start (Friday) no later than 7:15AM. We don’t want to set any drop bag size restrictions so please just use common sense and keep them reasonably sized and in sturdy materials.

All participants will receive a high quality race shirt along with other pieces of custom swag. Rest assured, we’ll find as MUCH stuff to give to runners as possible!
All 100mi and 100k finishers receive a custom finisher’s award.
100 mile finishers earn a custom MoS100 belt buckle.
Special awards for top runners of both races.

If you’re expecting predictable weather, then you’re in the wrong part of the country! With that being said, mid to late October is GENERALLY a beautiful time of year in eastern Iowa with temps historically ranging from lows in the upper 30’s/lower 40’s to highs in the upper 50’s/lower 60’s. That pre-winter precipitation usually doesn’t start rolling in until closer to November but we advise runners be prepared for any conditions especially during the overnight hours.

The race distance you start is the race distance you are scored in. There is no dropping down to the 100k after the race has begun. If you do, you will be entered into the final results as a DNF.
All runners, as well as their pacers and crews, must follow the rules listed below at all times during the event. Failure to do so will result in disqualification.

  1. Leave No Trace!
  2. Crew/pacers are ONLY allowed access to their runner at the Start/Finish.
  3. No cutting the course under any circumstances – any runner accepting a ride for any reason will be disqualified. If you leave the course for any reason, you must return to the spot you deviated from the original route and then continue from there.
  4. Trekking poles are allowed.
  5. Check into all aid stations.
  6. Cutoffs will be strictly enforced. Runner must LEAVE the AS by posted cutoff time.
  7. No muling from pacers and only one pacer at a time.
  8. Be respectful and courteous to all other trail and park users.
