The 2021 Aquafina OTC Butte To Butte 10K and 5K welcomes runners and walkers.
The Aquafina OTC Butte To Butte will take place on August 22, 2021. Due to the ever-changing situation with public safety guidelines and permitting restrictions, the event could not be held on July 4th of this year. The appropriate permits could not be granted under any risk level during statewide restrictions, and once the risk levels were removed at the end of June, the necessary resources for permitting were not available in a short period of time. Registrations from 2020 are carried over for the 2021 event. There are no refunds for this event. If the event is cancelled, your registration with be deferred to the next year. The 2021 event will hold a 10K run, 4M Mayor's Fitness Walk and 5K run/walk as in the past.
