Time on Trails is built for trail runners who believe preparation is part of the race. Think through the course, the terrain, the fatigue, and the decisions that shape race day. Build plans that match your abilities and help you execute with clarity.
Free to start. No credit card required.
The best plan reflects who you are, not who you wish you were. Preparation is part of the race, and clarity builds confidence.
Every climb has consequences later. Terrain shapes outcomes more than fitness. Understanding the course helps you make better decisions.
Your judgment matters most. See what you might be underestimating, understand your margins, and make informed choices that match your abilities.
Most race problems start hours earlier. Thinking through your strategy helps you recognize patterns and make decisions that age well.
Upload your GPX file or select from our race database. See your course as it actually is: not just distance and elevation, but terrain, surface, and cumulative fatigue.
The AI asks the questions you forgot to ask. It highlights what to consider based on terrain, weather, and your plan. You make the decisions. It helps you think them through.
Technology in service of judgment. The goal is awareness, not certainty.
Build your pacing strategy section by section. Account for cumulative elevation, terrain changes, and time of day. The bill always comes later.
Plan your nutrition strategy with precision. Track calories, hydration, and products at every control point. Make choices that support your energy needs throughout the race.
Upload a GPX file or choose from our race database. See the full terrain profile, elevation gain, and technical sections.
Set control points, plan your pacing section by section, organize nutrition, and review weather forecasts for race day.
Ask questions. Challenge assumptions. The AI highlights considerations you might have missed and helps you think through your decisions.
Export your plan, share it with crew, and race with clarity. After the race, compare against actual Strava data to learn for next time.
