Mount Shasta Tinman Triathlon Race Description

The Mount Shasta Tinman Triathlon is an icon for California which has been a major fundraiser for Dunsmuir Rotary Club, and one of the most enjoyable triathlons in northern California for decades.

Returning for years to come, the Tinman is now on a mission to partner with Rotary's critical passion of ensuring children have their meal needs met through the weekend, not just while they are at school. A portion of your registration will be donated to the Dunsmuir Rotary Club as they work with Wildcat Weekender, accomplishing their mission to feed the children who would otherwise not have enough food on the weekends.

Details of your adventure, cheered by the majestic view of Mt. Shasta include:

Fun, well organized race

This was my 2nd sprint Trinand what an experience! The course was challenging, but fun! Unfortunately it was quite smoky from fires, but that is typical this time of year. The volunteers were friendly and encouraging. There was someone directing us at every turn. The bike racks (new to Tin Man) were perfect! Nobody wants to lay their bike on the ground. There was fresh fruit and water at the end, which was nice. The buoys were pink flamingos, which were awesome! Defintely coming back!
