OTHTC Summer 2025 Challenge Series Courses

A new course will start each Monday, starting July 7, and run for two weeks. A link to the course information page will be posted here, on the Sunday before the start of the course period.

Each link provided in the Course Name column of the table below will take you to a page where you can view a course map, read a narrative description of the course, and access a course/route .gpx file on several website sources. That will enable you to make the route available to your course-capable watch or phone app. More information about navigating a route is available here.
