The Tutka Backdoor is an amazing backcountry adventure in a truly remote place. As such, it costs a little more to get out there than for most 50K runs. In our past experience (2021 and 2022), a group of runners sharing costs can run the trail for a little over $250 each, including the float plane and water taxi rides, chipping in for food at the campsite, and getting our camping gear from Homer to Jakolof.
