We have shifted the August 2020 Mountain Man event to 2021. We appreciate the strength and support of the multisport community. We have automatically shifted all registered athletes to the 2021 date.

We worked hard to create contingency, PPE, and safety plans, and will be sure to use best practices and USAT guidelines in our future events. 

In the mean time we have shifted to actively supporting and improving our local community during the pandemic. We hope that you have the opportunity to stay active, stay safe, and support your local community as well.

Race Fees / Registration


by ACTIVE Network

Early registration makes logistics easier and more cost effective for us, so the earlier you register the less you pay. Prices increase incrementally as we get closer to the event and have to lock in permit numbers and supplies.

Cancellation Policy

You can manage and Self-Edit your registration information through ACTIVE up until a week before the event.

Race Categories for Everyone

We offer Aquabike, Clydesdale, and Athena race categories with awards for the top 3 overall male and female in each of these categories.

Aquabike: Swim, bike, and be done. Whether you have bad knees, are working through an injury, or just plain don’t like to run, Aquabike could be the event for you. Your finishing time will be recorded as you cross the Bike In line at transition. From there you can take your time, rack your bike, then get your finisher medal and drop off your timing chip at the Finish banner.

Clydesdale and Athena recognize that not everyone is built the same way for endurance events. Brian Buzzard, Mountain Man Race Director, was a football player in college, and was crowned the Clydesdale USA Champion in 2019. To qualify for these categories you must be over a given weight (220 lbs. for males and 165 lbs. for females) and select the appropriate category when registering.

The Weather

Could be a little cool in the early morning and a chance of monsoon rain later in the day: perfect for racing. Low 80’s for the high.
