About Pacevine

Pace the mountain, not the average.

The problem we couldn't let go of

Every trail and ultra runner has done it: stared at a GPX and a finish-time goal and had no honest way to know how hard to go on each climb and descent. "Average pace" is a lie on terrain — the same runner can range from 6 to 20 minutes per kilometre across a single race. So you guess. You go out too hot on the first climb, and then people pass you for hours while your race quietly falls apart.

The tools that exist don't fix it. Some look like a generic dashboard. Some hand you a disconnected list of climbs with no pace attached. Most live only on your phone, useless at kilometre 70 in the dark. None of them feel like something you'd actually trust when it matters.

What we built

Pacevine turns a course GPX into one continuous, trustworthy pacing timeline — every segment with its own target pace, duration, cumulative time, and clock arrival, with aid stations dropped inline where they belong. It cleans the noisy elevation, splits the course into real climbs and descents, and accounts for grade, terrain, and the fatigue that builds over a long day.

Then it rides to your wrist. A Garmin data field carries the plan into the race and adapts in the moment — the one thing nobody else owns: live, terrain-and-fatigue-aware re-pacing on the watch, not a fixed plan that breaks the second the trail does.

Our Mission

We treat this like an instrument, not an app. An altimeter earns your trust by being legible and honest — so does Pacevine. Every number is sourced and explainable. We show the official elevation gain and explain how we compute pacing, rather than hiding a black box. We'd rather show our work — every pace, every assumption — than ask you to take it on faith.

And we're deliberate about what we don't do. We don't run ads, we don't sell your data, and we don't feed your training into anything you didn't agree to. The plan is for you, on race day.

Who it's for

Serious trail and ultra runners who respect the mountain and want to run their race on purpose. Built by people who line up at the same start lines — and who got tired of pacing on a spreadsheet.

Where we're headed

Trail and ultra is the beachhead. The same engine extends to road, crew logistics, nutrition, and a deeper race-day companion over time — one trustworthy pacing core across every surface and screen.
