Nstride is a free trail running route finder and planner. Preview any trail in a 3D flyover and break it into segments so you know the climbs, descents, and terrain before you run it. Our database includes over 100,000 routes worldwide with elevation profiles, segment breakdowns, climb structure, surface type, runnable percentage, and difficulty analysis. Whether you're training for an ultra marathon, exploring new trail running destinations, or planning a hiking adventure, Nstride helps you get a feel for the trail before you arrive. Each route shows you the terrain character and elevation changes section by section.
Nstride analyzes GPX files and route coordinates to show you what the trail is like before you go. Our algorithms identify climbs, descents, and flat sections, calculate difficulty scores, determine runnable percentages, and break the route into segments. You can explore routes by location, distance, or elevation gain, view interactive elevation profiles with color-coded terrain character, and preview any trail in a 3D flyover that follows the actual route path.
Nstride is a free trail running route finder and planner for runners and hikers. We analyze terrain, elevation, and difficulty for over 100,000 routes worldwide, providing 3D flyover previews, segment breakdowns, and elevation profiles to help you get a feel for the trail before you run it.
Yes, Nstride is completely free. Access route discovery, 3D flyover previews, elevation profiles, segment breakdowns, terrain stats, and all route information at no cost.
Each route is processed through algorithms that identify climbs, descents, and flat sections based on elevation data. We calculate difficulty scores, runnable percentages, longest climbs, elevation gain per mile, grade percentages, and terrain character. The 3D flyover preview and segment breakdown help you understand what to expect on the trail before you go.
Absolutely. While Nstride is built for trail runners, the terrain analysis, elevation profiles, and difficulty ratings are equally valuable for hikers planning trail adventures. Routes with singletrack, dirt, and gravel surfaces are popular among both trail runners and hikers.
Nstride includes trail running races (ultras, marathons, half marathons, 10Ks, 5Ks), training routes, hiking trails, and point-to-point courses. Routes span all distances from 5K to 200+ miles and cover locations worldwide, with a focus on trail and mixed-surface routes.
Use the interactive map on the homepage to explore routes by location, or browse by state and distance using our route directory. You can filter by distance categories (5K, 10K, half marathon, marathon, 50K, 50 mile, 100K, 100 mile) and view routes sorted by popularity and difficulty.
The 3D flyover preview is an interactive visualization that follows the actual route path over a 3D terrain model. It lets you see the climbs, descents, and surrounding landscape from a runner's perspective, giving you a feel for the trail before you arrive. Combined with the segment breakdown and elevation profile, it turns GPS coordinates into something you can read and understand.
