We are excited to announce a brand new course for the Windermere Marathon in 2024. A scheduled Centennial Trail resurfacing project will prevent the Windermere Marathon from using a large portion of Centennial trail in Spokane Valley for the 2024 race. It is with great enthusiasm that we announce our new flat fast marathon and half marathon courses. The half marathon course will be very similar to years past with only a change to the first 3 miles of the course. The marathon will be an out and back course for 2024 with a true chance to Negative Split your 2nd half of the course. There will also be a 10K and 5K distance.
