42nd Annual Mile High 100 Century Ride - Register Here!

June 20, 2026

Now in its 42nd year, the Mile High 100 promises to be better than ever! The recent road construction on Hwy 36 has resulted in smooth new pavement and wider, safer shoulders—especially up the challenging Johnson Grade.

Century riders kick things off with a climb to beautiful Domingo Springs, where pure spring water flows straight from the source into your bottle. From there, all riders take on the challenging Johnson Grade climb, spin through miles of forest (and visible reminders of the Dixie Fire’s impact), and finish strong along the sparkling shores of Lake Almanor

We’re also excited to announce enhanced rider support, including additional rest stops. Celebrate your finish with high-energy music from local favorite NextGen Entertainment.

And if you haven’t yet seen our iconic Mile High Cycling Jersey, be sure to check it out. Riders have responded with incredible enthusiasm! You can order yours when you register here.
