Run Rabbit Run 100: Accurate course map, mileages, GPX, and pace chart

It always looks better on paper.

The Run Rabbit Run 100 course was changed significantly in 2018. To assist future participants with race planning, at least until information from race organizers is more complete and accurate, I am sharing several resources:

  • Interactive course map
  • Course GPX
  • Mileage chart
  • Pace/split chart

Interactive course map

A topographic map of the course is available. However, it’s a static JPG image, and the course overlaid onto it is not always precise.

I recorded the entire 100-mile course with a Suunto Ambit3 Peak GPS watch, with its GPS ping frequency set to 5 seconds (“Good”). I was also wearing a Stryd foot pod, which is more accurate than the watch on its own.

The resulting track is fairly accurate; to get something better, a commercial-grade GPS unit would have to be used. Depending on your watch and your watch settings, the distances recorded by your watch may be shorter or longer than those recorded by mine, either consistently or inconsistently.

To create this interactive map, I:

  • Downloaded my race as a GPX file in Movescount.
  • Imported the file to CalTopo, my go-to mapping platform.
  • Added markers for the aid stations.

This map can be viewed with multiple map and imagery layers, including FSTopo 2016 (my pick), USGS 7.5-minute, Google Terrain, and Landsat.

View the map here, https://caltopo.com/m/F810.

Course GPX

If you would like a GPX or KML file of the course, export it from CalTopo at the link above. Depending on your intended use, you may want to only export limited data from my interactive map.

Mileage chart

Like the course map, an official mileage chart was available for the 2018 race, but it was a static file (in this case, a PDF) and it was not always accurate. For example, the official distances between aid stations were, on average, 0.42 miles (or 7 percent) off, and in one case listed a distance that was 1.3 miles short of the actual distance.

Using the GPX track recorded by my Ambit, I created a new mileage chart, below.

Pace/split chart

Last year I posted in in-depth tutorial on creating pace charts for ultramarathons. I won’t repeat the process here.

As the “model race,” I used splits from the 2018 winner, Jason Schlarb, who seemed to run a more even race than other elites like Jeff Browning, Seth Swanson, and Kyle Pietari (who all had rough patches), or myself and Jeff Colt (who started too aggressively and faded later).

    I used your pace chart tutorial with some modifications and drawing lines in caltopo to make my own profile data to help a friend prepare for Mogollon Monster last month. I don’t run distances longer than half-marathons, so it’s not for me, but I did immensely enjoy the analytical work of helping her prepare, and your guidance was instrumental, so thanks!

    Steve Clark appears to be amused by your post race pass out.

    Did your footpod last the entire race? Is it supposed to be 20 hours on that?

      Yes, it went the duration. I don’t know what the lifespan is, but I feel like I very rarely have to recharge it, even when running 15 hours per week.

    I was told by the RDs that they plan on changing the course again for the 2019 running of the event.

      Sounds like it’s a possibility but not a definite. Will be contingent on some trails being built and on permitting for commercial use of public land.

    Great info! Not sure how many of your readers are ultrarunners and appreciate the race-related info, but I enjoy it quite a bit. Nice work on a tough course – what else do you have on the schedule this year?
