Denali135 and Denali100k Race Ambassadors

Ronnie Delzer

Ronnie's results are too long to list here but include a 100 mile PR of 13:40, 2017 & 2018 USATF 100 mile Champion, and Guinness World Record Holder for 12 hours on a treadmill with 89 miles.
We're pretty sure Ronnie is going to crush the 2019 Denali135 course record.

Check out Ronnie's website & follow him on Instagram.

Dan Brenden

Dan is the ultra legend you've probably never heard of.  He's the record holder of Ultra Grand Slams at 8, 11 Western States finishes, 8 Leadville finishes, 12 Vermont 100 finishes.  112 hundred mile race finishes!  
Maybe the greatest thing about Dan is his kindness and unassuming manner.  He's a heck of a nice guy!

Giving Back

Contributing back to the communities where we hold our races is super important to us at Spirit Trips.  In the case of the Denali135, we have chosen to raise awareness and donations for the Denali Education Center who also happens to be graciously allowing us to hold our Denali135 post-race award dinner at their super cool Charles Sheldon Event Center on their campus 15 minutes south from Denali National Park.

The people at The Denali Education Center strive to bring awareness and appreciation for Denali National Park and their programs and outreach range from taking visitors on 2 hour interpretive guided natural history walks to multi day immersive nature programs for youth who without the Denali Education Centers outreach and passion, would never have a chance to experience the wonder of Denali.

Spirit Trips will be donating a portion of each race registration fee to The Denali Education Center and we strongly encourage our runners and their crew & pacers to do donate however they feel they can.
