Thanks for reaching out! Currently, the API does not pull the .gpx data from the site. It is possible to manually download GPS tracks for personal use, and this can be done from the trail page. Were you hoping to use the files for your personal use in the field, or were you hoping to create something new using our data? Let me know, and we can work on solutions from there!
Gotcha, thank you for letting me know. While you can download the GPS information for each individual trail, I'm not sure that that function would work for accruing a large volume of GPS data at once. If there's anything else that I can help with, please let me know!
Best of luck in Boot Camp - it sounds like you're working on a great project!
