 GPX 文件通常只包含一条轨迹，且该轨迹仅有一个路段。不过这个层级结构支持高级用法，例如用来规划多日旅程且每日可包含多个行程信息。
 
+### <Route size="16" class="inline-block" style="margin-bottom: 2px" /> Routes
+
+A **route** is a single continuous path made of a sequence of **route points**.
+These are mandatory checkpoints, which correspond to the anchor points of the [routing tool](./toolbar/routing).
+The points in between are only a suggested path connecting the route points.
+Like a track, a route can have a **name**, a **description**, and **appearance properties**.
+
+<DocsNote>
+
+Nowadays, most apps and GPS devices work perfectly well with tracks, even for navigation.
+However, some of them only work with routes: in that case, you can [convert](./menu/edit) your tracks to routes, or [create](./menu/file) a route file from the start.

 **兴趣点**（_航点_）用来表示 GPS 设备或数字地图上需要显示的特殊位置。
