A course for PR's

A Course Known For PR’s

The Windermere Marathon and Half Marathon boast flat and fast courses along the Centennial trail that keep runners coming back year after year. The Windermere has a net negative elevation gain.

Half marathon: http://www.mapmyrun.com/routes/view/1420651972

Boston Qualifying:

The Windermere Marathon and Half Marathon will again be  USATF certified courses and the marathon will be a Boston qualifier.

Water Stations:

Water stations are located approximately every 2 miles with 13 total stations on the marathon course, and 7 on the half marathon. All aid stations will contain water, GU hydration, GU chews, and GU gels.  Portable toilets and basic first aid are available at each station as well.

Medical Aid Stations:

Full medical tents will be located at Mirabeau and at the Finish Line staffed by Providence medical staff. We will also have a bike patrol along the centennial trail and roaming ATV to assist runners in the case of an emergency.

Train Crossing:

At Mission and Upriver Dr. both distances cross a train track, which unfortunately we don’t have the ability to stop. In the event that the train crosses at this location, there will be course marshals stationed at the crossing to record your bib number and the amount of time you were held up. Time corrections will be made to your final finisher time to adjust for any train delay.

Course Time Limit:

The course will remain open until 12:30 PM.  This allows 7.5 hours for the marathon walkers, 5.5 hours for marathon runners, 4.5 hours for half marathon participants.


The best access points for spectators will be at both start lines and the finish line. Spectators will also fine easy access to view runners on the Centennial trail at the trailheads of Harvard Road, Barker Road, Sullivan Road, Mirabeau Park and along Upriver Drive east of Mission.

Course Rules and Timing:

Timing and results will be produced by Nomadz Racing (nomadzracing.com). Timing chips will be fixated on the back of your bib number and will read when you cross the finish line.

The rules below must be followed at all time or it may result in a disqualification.

  1. Running with strollers is not allowed due to the narrow course along the centennial trail and runner congestion.
  2. Running with a pet is not allowed for the safety of other runners and due to runner congestion.
  3. Headphones are strongly discouraged for your own safety and the safety of those around you.  If you must run with headphones, we ask that you only put it in a single ear to be able to hear traffic, course marshals, and other runners around you.
