Ultramarathon
Your ultramarathon was one day. The build was most of a year.
Skoma turns your ultramarathon training block and race day — every back-to-back weekend, every metre of vert, every hour out there — into a printed hardcover photo book.
Questions? See the FAQ below.
How it works
- Bring your training. Connect Strava, or upload GPX, FIT, or CSV files from any watch — race day and every training run included.
- We build the book. A training-season overview (monthly volume, total climbing, a day-by-day heatmap), then race day itself — route line, elevation profile, splits — and the moments around it.
- Edit anything, then order. Fix stats, swap photos, pick a theme — then order the hardcover from $49.99 with 50 pages included and free worldwide shipping.
What's inside the book
- The build. Total distance and total vert, monthly volume, and the day-by-day heatmap that shows the back-to-back weekends for what they were.
- Race day. The route line, the elevation profile, and your splits across however many hours it took.
- The hours nobody photographs. Night sections, aid stations, the low patch, and whoever crewed you through it.
- The finish. Or wherever you stopped. Both make a book.
50K to a hundred miles, road or trail
Set the race type to Ultra or Trail Race when you create the book. The distance, moving time, and elevation are read from the activity itself, so nothing is capped at a preset — a flat 50K and a 30-hour mountain hundred are laid out by the same rules.
Ran a road marathon instead? See the marathon book. Walked a long trail rather than raced it? That's the journey book, which gives every day its own page instead of building to a single finish.
Ultramarathon book FAQ
Which ultra distances does this work for?
Any of them. Set the race type to Ultra or Trail Race when you create the book; the distance, moving time, and elevation all come from the activity itself, so a 50K and a 100-miler are handled the same way. Timed and backyard formats work too, because the book reads what your watch recorded rather than a distance you declare up front.
What if I did not finish?
The book still works, and this is the case it handles best. Most of its pages are the training block: the months of volume, the back-to-back weekends, the climbing. That happened whether or not you reached the finish line. Keep race day in as far as it went, or leave it out and let the build be the story.
Does it show elevation and total vert?
Yes. Total elevation is one of the built-in stats, and race day gets its own elevation profile alongside the route line and your splits. For most ultras the climbing is the real story of the day, so it is not buried in a footnote.
My race took more than a day. Is that a problem?
No. A single very long activity is treated like any other, so a 30-hour hundred-miler lays out fine. If your watch died and you recorded the rest as a second activity, include both and they sit side by side on race day.
Do I need Strava?
No. GPX, FIT, and CSV files from any watch work too, or you can enter your key sessions and race day by hand. Strava just makes it faster.
How long is the book, and what does it cost?
$49.99 for the linen hardcover with 50 pages included and free worldwide shipping; extra pages are $0.99 each. Ultra blocks are long, so they run past the included pages more often than a marathon block does. Creating and editing is free, and you only pay to print.
How is this different from the marathon book?
Same editor, different centre of gravity. A marathon book builds toward one day and treats the race as the climax. An ultra book gives more room to the build itself, because the interesting part is usually the volume, the vert, and the back-to-back weekends rather than a finishing time.
