Made for everyone on race day
The runner sets it up, the crew keeps it current, and everyone else follows along. Each has its own video, about a minute long.
No. 1
Runners
Set it up once, then run.
- Your own page at yourname.trailmark.run, with your distance, wave and goal time. Your loop-by-loop plan comes from your goal.
- Pick your page's colors and add a cover photo. Change either any time.
- Log your own aid stations with one tap in runner mode, or with an iPhone Shortcut.
- Add your bib, and your splits can come in from the official timing mats.
No. 2
Crew
Keep everyone posted without a group text.
- The runner adds you by email. You sign in with a 6-digit code; there's no password.
- Tap when your runner reaches an aid station. Undo it, or fix a split, if you tap the wrong one.
- Post race updates everyone sees, and pin the one that matters most to the top.
- No signal is fine: taps and posts wait on your phone and send themselves when signal comes back.
No. 3
Family & friends
Know where they are, and when to go see them.
- Where they are: miles, loops, percent done and a dot on the course map.
- When to see them: the window for their next pass through the crew zone, updated with their real times on race day.
- Alerts when they're on their way to the crew zone, when they get there and when they head back out, plus every crew update. Switch on Every aid station for the other stops too. On iPhone, add the page to your Home Screen first.
- A cheers wall anyone can write on, with reactions and replies.
No. 4
Spectators
Follow up to 30 runners on one race page, or put the race on a TV.
- Add runners who have a Trailmark page: tap Follow on their page, or find them by name on the race page once they've chosen to be found. You'll see their mile, ahead or behind plan, and estimated finish.
- One course map with each runner's last known spot and an estimate of where they are now.
- A feed of aid-station check-ins, crew updates and cheers, and links to the official tracker and race info.
- TV mode for a big screen: the race clock, a map of every runner you can find on the race page, and their feed, with nothing to tap. Open trailmark.run/javelina?tv in the TV's browser.
No. 5
Coaches
Your whole team on one page.
- Coach teams are set up by hand for the Javelina. Ask for one at switchback-labs.com.
- Invite your runners by email, or add them yourself with a name, distance and bib.
- On race day: every runner on the course map, who's coming into Jeadquarters next, and how each is doing against plan.
- Log a split or post an update for any runner on your team.

Made for race day
Works with no signal
Signal at an ultra comes and goes, on the course and at the crew zone. Trailmark keeps working when it drops.
Pages still open
A page you've opened once opens again with no signal, showing the last spot, splits and updates it got.
Last updated Sat 2:14 PM AZ · offlineTaps and posts wait
Aid-station taps, crew updates and cheers made with no signal stay on the phone and send themselves when signal comes back. Nothing is lost or sent twice.
Offline · 2 will syncIt catches up
When signal returns, the page fills in what it missed on its own. No refreshing, nothing to retype.
Syncing…
Before race morning: open the page once with good signal. That's all it takes for it to work without.
Questions
Before you start
Is it free?
Yes, for everyone. Starting a page, crewing it, following it and coach teams all cost nothing.
What if there's no signal at the race?
Trailmark keeps working. A page you've opened once on your phone opens again with no signal and shows what it last knew, with the time it's from. Aid-station taps, crew updates and cheers made with no signal wait on the phone and send themselves when signal comes back, once each.
Open your runner's page once with good signal before race morning, and it's ready.
Does anyone need an app or an account?
Nobody following you does: your page is a website, and reading it, cheering and getting alerts all work without an account. You and your crew sign in with your email to post.
On iPhone, alerts work once the page is added to the Home Screen (iOS 16.4 or later). The page walks people through it.
How does my crew sign in?
You add them by email from your admin desk. They get an email with a link, then sign in with a 6-digit code we send them. There's no password to set up.
Which races does it work for?
The Javelina Jundred on Oct 31, 2026: the 100 miles, the 100K and the 31K (the Jackass Night Trail). It's the first race on Trailmark, and more come after it.
To see what's coming, for races and for the app, look at the roadmap. To ask for your race, send us a note.
Is Trailmark part of the race?
No. Trailmark isn't affiliated with the Javelina Jundred or Aravaipa Running. For official results, use the race's own tracker.
Is there live GPS tracking?
No. A runner's spot moves when an aid station is logged: by a crew tap, the runner's own tap in runner mode, an iPhone Shortcut or, with a bib on the page, the official timing mats. Between aid stations the map shows an estimate from their pace.
Who can see my page?
Anyone with your link. If you let people find your page (it's on when you sign up, unless you untick it), they can also find it by your name on Trailmark, on the race page and through search engines like Google. To stop that, turn off Show my camp on the race page in your admin desk's settings, or hide your name there and show a nickname instead.
Your crew has enough to carry.
Give everyone else one link, and let your crew get on with crewing.
Trailmark starts with the Javelina Jundred. More races and features come next, and real iPhone and Android apps are on the way. See the roadmap
