The Course
******The 2024 course will most likely be altered due to construction at Eagle Island to the addition of a campground and another pond. I won’t be able to have the actual course out until mid February at the earliest. Stay tuned***
We’ve added the 100 Mile Relay back to Pulse Endurance Runs for 2024!!
You were always looking for a timed race without pavement hurting your feet right? At the Pulse Endurance Runs, you can enjoy nature while running on a beautiful flat dirt trail 2 1/2 mile loop bordering the Boise River and Eagle Island pond. See the website for all course details. This is a great course to get your first ultra, anywhere from a 50K to 100 miles and beyond!

The Race
The Pulse Endurance Runs are a beautiful and flat fixed-time race held at Eagle Island State Park, 8 miles west of Boise, Idaho. Test yourself against the clock and some of the northwest’s top timed event runners at Idaho’s premier timed race on a flat, dirt trail. Set a goal and achieve it, running as many miles as you can in 48, 24, 12, or 6 hours. Or, sign up for the 100 mile fixed-distance option! We added the Relay back so bring your friends and run with up to 5 of your friends. Contact the RD if you’re signing up for the Relay and have less than 5 runners and I will adjust the price accordingly. This must be done prior to registering.
Come for fun, or come for speed….just bring your smiles!
No refunds will be provided, including in the event of a cancellation outside of the organizers control.
YOU MUST BE REGISTERED BY MARCH 3rd TO BE GUARANTEED FINISHERS SCHWAG

Race Times
We have a lot of event options. Make sure you are checking the start times and signing up for the race you intend to!

100 MILE RELAY
You can have up to 5 runners for the Relay. If you have less than 5 please let the Race Director know PRIOR to signing up and the registration fee will be adjusted accordingly. You would need to do this before you register.
You will be passing the timing chip to the next runner inside the designated transition area at the start/finish only. Your team can decide who runs when and how often. Each team member is not required to run the same amount and they don’t have to run it all at once. If a runner leaves the park for any reason they are not allowed to run again. No Pacers allowed in the Relay.

You can have a little extra fun in the Relay and join us in the ‘Best Name/Costume contest.’ We’ll be giving a special prize to the team with the best name/costume. The costume must be worn the entire time and the costume theme must match your team name. I know we have some pretty creative runners out there, I can’t wait to see what you come up with!
