Other GPX Files
Wordpress free hosting is an excellent service, but they don't allow GPX files to be downloaded directly. There are other excellent free sites, like trailrunproject.com that host GPX files, but require you to create a (free) account and log-in to download them.
Most people are OK with using free accounts and the tracking that comes with them to get useful information, but some aren't. As such, not only do I provide GPX files for the races I direct, I will also add GPX files for other events so that people who wish not to be tracked can download them.
