You can reverse a trail route using either a desktop or laptop computer at alltrails.com. This can only be done on our website and is not yet available in the app. Once you've reversed a route and saved your map, you'll be able to find it in the app by tapping 'Saved' >> 'Lists' >> 'My maps.'
You'll first search for the trail you wish to complete, then hover over the 'More' icon from any trail details page, then select 'Customize map.' The trail map will then be copied and displayed in the map creator tool, where you can customize it to your liking.
You can then click the overflow menu (three dots) next to 'Route 1' and select 'Edit'. Then click 'Reverse' >> 'Save' >> 'Save custom map.' You'll then be able to access this map via the app by tapping 'Saved' >> 'Lists' >> 'My maps'.
