For runners & cyclists who train on terrain
Train for the terrain. Ready for the race.
Pendio turns every climb and descent into numbers that actually mean something — and when there's a race on the calendar, it maps the course and plans your fuel.
Private beta · no spam · just a heads-up when it opens.

Most apps treat a flat 10K and a 1,000 m grind the same.
Pendio doesn't. It reads every segment of terrain — climbs, descents and everything between — so the numbers reflect the effort the ground actually demanded.
Race day
Import a route. See exactly what you're in for.
Drop in a race GPX and Pendio maps the ground ahead — the hardest climb, the hardest descent, and whether the vertical is front- or back-loaded. The course profile is the hero of the screen, not a footnote.

Readiness
Are you ready for the terrain?
Pendio compares your recent training against the race's real gradient mix and gives you one honest read — volume, longest session, weekly climbing and terrain match. It's a heuristic, not a verdict, and it says so.

Fueling
A fueling plan shaped by the course.
From your target time and carb rate, Pendio works out the whole day — total carbs, gels, and an hour-by-hour timeline that tells you where to fuel at the base of a climb and where the long descent gives you room to eat.

Terrain-based load
Numbers that describe the ground, not just the distance.
Beyond pace and time: grade-adjusted pace, the steepest 100 m up and down, decoupling, and a descent-load index for what the downhills actually cost you.

Load, with the race in sight
Watch your load build toward the start line.
Pendio tracks load week over week against your chronic baseline — including descent load, the part most tools ignore — and counts it down to your target race, so you know whether you're building, peaking, or overcooked.

Climbs that count
Every climb, found and ranked.
Pendio detects the real climbs inside every activity and ranks them by toughness — score, VAM, grade-adjusted pace — so you can see exactly where an effort was won or lost, and how the same climb trends over time.

Questions
What kind of athlete is Pendio for?
It's built first for trail and ultra runners — anyone whose races are decided by climbs, descents and fueling. Road runners and cyclists who train on hilly terrain get the same grade-aware analysis; sport is never the thing Pendio colors, the ground is.
Do I need a special watch or device?
No. Pendio reads the activities you already record and sync to Strava. If your file has GPS and elevation, Pendio can analyze its terrain.
How does the race analysis work?
Import a route's GPX and Pendio profiles its terrain — hardest climb and descent, how the vertical is distributed — then compares it against your recent training to estimate readiness, and builds a fueling plan from your target time. Every figure is descriptive and attributed; it never invents data it doesn't have.
Where is my data stored?
On your device. Pendio uses Strava only to read your activities, and does all of its analysis locally — there are no accounts on our side and nothing is uploaded. See the privacy policy.
