City of Trees Marathon

Saturday, October 10, 2026
Course Maps will be updated once details have been finalized.

GREAT SWAG and T-SHIRT DEADLINE
Comfiest long sleeve t-shirt, swag thanks to our amazing sponsors, and finisher food/drink, all COT runners get a finisher's award. Please note that registrants registering after October 1, 2026 are not guaranteed a shirt.

Please note courses utilize the Boise Greenbelt system. Should we run the Greenbelt, the river can be unpredictable. Systems and entities that govern the local Greenbelt are constantly dealing with these challenges. Typical issues are created due to sidewalk construction, sinkholes, flooding, etc. During the run, you may encounter wildlife that may cause a delay in your progress and/or change in your planned route. Or you may cause your own delay to stop and listen to the amazing sounds this course creates. 

We love this river. A water flow that originates from the snow-capped peaks of the Sawtooth and Boise mountains, our race courses will get you intimately close to the sounds of the river as it winds through a rocky canyon and melts into an urban setting. We do reserve the right to make changes as we can't be boring.

DISCLAIMER - All routes are subject to change at anytime. Please check back often.

HYDRATION STATIONS

Participants will cross Hydration Stations roughly every two miles on the course. Hydration Stations will be equipped water, sports drinks, and fuel,  first aid & awesome folks cheering you on! Just a note, we do place emphasis on placing Hydration Stations on critical portions of our race so that may affect distancing. For example, turns and turnarounds seem to work better when at a Hydration Station. 

Please do not litter on course and dispose of your trash at the Hydration Stations. We do have a team that sweeps the entire course for garbage post race, but please make their life easier and do not litter on the course.

UPDATE: AUGUST 28 - The City has reviewed the original 2002 route request and unfortunately did not approve the use of roads this year. Instead, they’ve recommended that we shift the course back onto the Greenbelt. We’ll be releasing updated maps and details shortly.

Please note: with Ada County’s closure of portions of the Greenbelt, our ability to extend the course west towards Garden City and Eagle will be limited. We’re working closely with the City to finalize the best possible course within those parameters, and we’ll keep you updated as soon as we have confirmation.

PLEASE NOTE: We are looking for additional people to be our BRIDGE TROLLS.

Timing, Results and Awards

Q: Will you have a timing mat at the start (chip start)?
A: YES!!! The timing company will have timing mats at the finish line for the 5K, 10K , Half Marathon &  Full Marathon. In keeping with USATF standards, the awards will be based on GUN TIME.

The top 3 Overall Male & Female for each distance and the top 3 overall for age groups will receive awards. ALL finishers will receive a City of Trees finisher's medal! 

Q: When will you post results?
A: The timing company will post live results, so you'll be able to see your UNOFFCIAL finish time almost immediately on your smartphone. Official results will take longer to process and post, since the timer will need to resolve various issues which are bound to crop up.... we think that's how it's supposed to happen.
