Great! Now that you have the GPS track recorded, if you head to your profile on the website, you should see a section titled "Private Recorded GPS Tracks". Click on the recorded track that you would like to make public, and on the right hand side, you will see an orange "Share on Trail Run Project" button which will allow you to publish your track.
There is one small hiccup with this process which is that in making the race public, it will automatically be added to the site as a trail as opposed to a featured race (this is a problem with our workflow). I can go ahead and change that trail to a featured race for you once you get it published if you can please send me a quick email at firstname.lastname@example.org with the link to the race page.
