Turnsheet equips runners of all abilities with the information they need to find and conquer the right trail race. From past results to future weather forecasts, we have a wealth of knowledge to share — all designed to give you an edge on your goals.


Our Motivation (A Quick Story)

The race report started with the ending.

It didn’t gradually build suspense nor offer a redemptive storyline. It didn’t make the reader wonder if the tide would turn. No, the report cut right to the chase: DNF.

Going on to explain in greater detail, the author said he decided to throw in the towel at mile 41 after “battling severe, full-body cramping” since mile 19. The culprit, it turned out, was the unexpectedly hot and muggy weather. Daytime temperatures reached 88 degrees and the humidity gauge never left 100%.

But the headline of this race was not heat.

The author had read other race reports and was well-prepared for the race’s technical terrain (he brought poles) and penchant for rain (he left jackets in multiple drop bags). Heat, however, wasn’t supposed to be part of the equation. “The race,” the report concluded, “was a lot harder than it seemed on paper.”

This got us thinking. How could a 20-year-old race not be well-known for a factor, like heat, that can weigh so heavily on a runner’s success? Surely, in the multitude of great race reports out there, a few credible runners had proclaimed, “Beware of the sneaky heat!”

So, we took a closer look at other race reports and found an interesting trend. This was an east coast race and local runners didn’t consider 80 degrees abnormally hot for a summer 100-miler. A Mid-Atlantic runner emphasizing summer humidity would be like a Pacific Northwest runner emphasizing winter rain: some things just go without say.

When the race report author — who, yes, hailed from the Pacific Northwest — researched the race, we have to imagine he didn’t find too many conversations about the brutal heat.

As ultra-marathoners ourselves, we know how much a DNF can hurt. A “drop” can easily throw a runner into a cycle of self-doubt and dismantle an entire running season. Hell, a DNF can even prevent a runner from taking another shot altogether.

We wanted to make DNFs far less likely. We wanted to make it easier for runners to take a closer, more objective look at a race and position themselves for success — no matter what a race throws their way.

Build Around Runners

Runners are at the center of Turnsheet. We designed it to “push” qualified suggestions to you — not wait for you to wade through an exhaustive list.


Driven by Data

Trail races generate loads of data, all of which can be translated into learning and planning opportunities. We thoroughly train our lungs, legs and heart for a race — now it’s time to do the same for our race plan.

Featuring Races That Make Sense For You

Don’t want to run a race with more than 2.50% paved road? Prefer to avoid 100-milers that take 48 hours hours to finish? No problem — we’ll remove them from your list.

We’re starting with North American 100-milers and expanding from there. We promise at least five new races a week.

It’s a mixture of endorphins, fatigue, and the feeling that your body is spent. You get to the finish line, have a post-race bourbon, and swap stories with other runners.
