Mostly a great app

We primarily use this app when running or hiking in unfamiliar terrain. It’s a great way to check location via GPS if you think you may have gotten turned around when deciding to try a new trail with poor signage or missing blazes. Also a pretty good option for looking up running options when traveling. My one beef is that some of the trails available on the website (including popular race routes) don’t show up in the app. In some cases you can even download a GPX file of the route from the desktop website, but you can’t load it into the app, and the trail/route doesn’t show up in app. Seems weird for Trail Run Project to have complete, downloadable GPX data for routes but for them not to be included for use with app.

Needs some work - what gives REI?!

First of all, I love the idea of this app. Super cool idea, and it seems like it even works well. It has all the info I want when I’m looking for trails. BUT... you can’t update any info from the app it seems like. You also can’t upload pictures, which to me, a non-tech person, seems like it’s both important and shouldn’t be super hard to add in. Until they fix the “go to our website to add xyz” it seems like they rushed it

I have no complaints.

I’m an avid trail runner and in Colorado there are literally hundred of trails within an hour of me. This has been amazing at helping me find all the hidden gems! If you are just trying to discover new trails or have been trail running for a while GET THIS a APP.

Best features:
The feature that takes you directly to google maps to find trail heads. It makes planning routes and deciding which trails are worth my time so much easier.

Updated trail conditions, which is super helpful in the spring and winter months

Ability to add trails to a “to do list”

The descriptions are so detailed from elevation maps, personal reviews and tips, pictures.
