I was looking for fire closure and restrictions for the Kaibab Nat Forrest and ran across some bike events they have going on. the first one is 18 mile fun ride on a section of the AZT May 13th

The other one is AZT In a Day. you pick a section of the trail you want to ride or hike and you have 24 hours to complete that section.
here is the link to that one
