From time to time you may notice a trail listing here on Singletracks.com that doesn't have a “Map” tab on its page, or a pin on the map of its state. This is because there isn't a latitude/longitude location entered for the trail.
As users, we can help fix this issue, and the pay off is that it'll be easier to find trails to ride... and of course, you'll get more contribution points. :) I've already randomly opened the mobile app and hit “nearby trails,” and had it pull up locations that I've entered data for. It's a very satisfying experience.
Depending on the trail listing, locating the trailhead might be quick, or it might take some work. Here are a few pointers:
First, you need a trail without a trailhead location. You may stumble across one on accident, or you can go looking. A good place to start may be your own state or country listings.
Next, it's just a matter of clicking the "Add Location Info” button on the right side of the trail page. I personally like to open it in a new tab so I can keep the directions open and refer back to them.
This will open a Google map centered on the listed city. If the directions included in the original listing are detailed, just follow them on the map until you find the trailhead--otherwise you'll have to work for it. If the directions aren't detailed, try searching the web for the trail name, town, and words like map, brochure, trail, mountain bike, etc. Something will usually turn up. Also, the websites of state and local trail building clubs tend to be helpful.
Once you find the right spot, click the circle by “Add point of interest," then click on the map. To add a trailhead location, fill in the “Waypoint name" field, and click save.
Then, fill in a “Map name,” and click “Submit.” In a few days, once the trailhead location has been review and approved, the trail will finally show up on the map. Mission accomplished!
