Trail Run Project is a trail running app that helps you find, plan, and follow running routes before and during your outing. According to its description, it offers the level of detail you would expect from a traditional map, with full GPS route information, interactive features, elevation profiles, and photos. The description states that the app covers over 74,000 miles of trails.

Planning a run before you leave

The elevation profiles and trail insights are the main planning tools described in the app. Viewing the climb and descent of a route in advance lets you compare trails and choose one that fits your current abilities and goals. The description also notes that the interactive features show highlights and challenging sections of each trail, so you can learn the layout of a route before you start running on it.

Finding trails in new areas

When you want to explore a region you do not know well, the search function is the documented way to look for trails in that area. Combined with the route details and photos, it can help you find options you might otherwise miss while you are still deciding where to go.

Running where cell service is limited

The app can be used offline. You can download trails in advance and access them without a connection, which the description presents as useful in areas with no cell reception. This is the main way the app supports runs away from network coverage.

Keeping trail information current

The developer describes the trail database as being updated regularly, so the list of available trails can change over time. Users can expect newer routes to appear without needing to set up anything additional, as the description does not mention a manual process for this.

Syncing your plans with TrailRunProject.com

The app includes a sync feature that brings your to-do list, check-ins, and favorites from TrailRunProject.com into the app. According to the description, this keeps your trail running information in one place across both the website and the app.

Battery use with background GPS

The description warns that using GPS in the background may drain your battery. If you plan a long run with navigation, it is worth monitoring your battery level during the outing.
