Special Event Permit Application: theMAMMOTH

Good afternoon,

Mono County is presently processing a Special Event Permit application for theMAMMOTH, a 200-mile running race around the Long Valley Caldera. The race, as proposed, will continue through evening hours and, on the evenings of Saturday, September 27 and Sunday, September 28, the event organizer has proposed overnight use of the Lee Vining Community Center as an aid station where race participants can resupply and recover, with cots available for participants to catch some sleep.

This special event permit will be considered by the Mono County Board of Supervisors at the September 9, 2025 meeting. The meeting will occur at 9 am in Bridgeport, with remote participation available in Mammoth Lakes or online. Please see https://monocounty.ca.gov/meetings?field_microsite_tid=407 for more information on the September 9 Board meeting, including the agenda and zoom link for remote attendance. (Please note that meeting documents will not be uploaded to this webpage until about one week prior to the meeting date.)

More information about the proposal is attached. A digital, interactive map of the race route is available at https://caltopo.com/m/J5NQV. 

If you wish to comment on this special event permit application, but are unable to attend the Board meeting on September 9, 2025, please reach out to Aaron Washco, Mono County Risk Manager, at awashco@mono.ca.gov to provide your comments in writing.
