About the Plain Endurance Runs
The official name of this race is The Plain100+ Mile Endurance Run (David M. Smith Memorial 1953-2011) in honor of Dave, a Search and Rescue team (SAR) member who was with the race from the beginning until his death in 2011. The Plain 100 is a challenging 100+ mile ultra marathon (even by ultra standards) over trails in the mountains near Lake Wenatchee and Plain, Washington. The course contains more than 21,000 feet of elevation gain/loss with no support for the runners. The race details can be found at Starting in 2014, a Plain 100K race will be added with the same checkpoints and route similar to the first loop of the 100 mile course.
About the Support Team
The support team is present to account for all the runners, call in times and render any aid necessary - for those that drop. The terrain is challenging for both the runners and communications. There are only a couple repeaters that work at all and those are not ideally located for the course. Support team members must navigate over unimproved roads and operate independently for long periods of time. The support team operates with the amateur radio callsign of N7CGA which was previously owned by Dave Smith who co-founded the support team with Steve Dazey. Tim Dehnhoff, KD7IGJ has been with the race since 2000 and is the current support team commander. Tim is a 20 year veteran with Snohomish County Search and Rescue and an amateur radio operator since 2000. Starting in 2016 Tim Dehnhoff will be Co-Race Director alongside Tim Stroh (10 time Plain100 mile finisher).

We have been fortunate to have an extremely skilled team.  Each member must complete an interview process with Tim Dehnhoff, team commander.  If you feel up to the challenge, contact Tim at dehnhoff100 at  If you can participate and have been approved, please complete the team signup form.

The support team has a private Google Group that is used to communicate directly with team members.  All team members should be subscribed to this group to receive the latest communications.  It can be found at
