UTMB data: Results, split times, course GPX, & pace charts

If you plan to race UTMB — or use the course as a training camp — and if you’re a data dork like me, the resources on this page will be useful in your preparations:

Official results

At the UTMB website, official results are available for each year, back to 2003. The more recent years include split data from 20+ checkpoints.

The course has been modified several times — by design or due to race-day conditions — so the results are not necessarily comparable across years. The current official course was followed by racers in 2015 and 2016, but not in years prior and not in 2017.

From LiveTrail, the timing company hired by UTMB, you can get the official results and some more granular data, plus some graph/chart options: 2017 results.

Course GPX file download

Maps of the UTMB course are available on the UTMB website, but they’re not very useful due to the resolution. And because the course is not marked until a few days before the race, it’s difficult to know exactly where the course goes in areas where there are lots of options (e.g. in the towns, in ski areas with lots of trails).

Download a GPX file of the UTMB course.

The file is based on the data I gathered during the 2017 race using my Suunto Ambit3 Peak, which recorded my location every 5 seconds. Three changes were made to the 2017 course; the official segments are also included in the GPX file:

  • Bypass of Col des Pyramides Calcalres
  • North of La Fouly, we ran on roads and tracks rather than trail
  • Bypass of La Tete aux Vents

Split charts & pace charts

Essential: Read my pace chart tutorial, which includes a discussion of its value and my process for making one.

My UTMB pace chart is available for download. Click here. To make your own copy of the chart, sign into Google and “Make a copy” under the File menu.

The pace chart assumes the official course, an official time chart for which is available under “Time Chart” on this page. (Note: As of Sept 13, the time chart posted is for the modified 2017 course.) If there are permanent or last-minute changes to the course, some split and pace data will no longer be accurate. Unless I run UTMB again, I probably won’t update the data, so buyer beware.

You will want to hide rows and columns in order to make the pace chart more user-friendly. This was my print-out (“laminated” with packaging tape) for the race:

Before the race, I settled on a 24-hour goal time. I had 23- and 25-hour splits ready to go, depending on different race day conditions or circumstances. My goal splits were proportional to split data from 2015 and 2016 races that I hoped to emulate, like the performances of David Laney and Seth Swanson. You will need to adapt the pace chart for your own purposes.
