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!
100 Mile Relay is back!! Bring 1-5 of your favorite running buddies and see how fast you can run 100 Miles. You get to choose how many loops each person does.. Come for fun, or come for speed….just bring your smiles!  YOU MUST BE REGISTERED BY MARCH 8th TO BE GUARANTEED FINISHERS SCHWAG

New for 2019!  We’re adding a little party to liven up your loops!

    The party starts Friday at 8PM next to the old prison bunker house and lasts until the sun comes up!  The party station captain, one of our favorite local ultra runners, Kari Porter and crew will be handing out beads for those adding to the party as they pass through!  We may have a little something special for the one with the most beads at the end 😊

We’re also adding a costume contest so everyone can join in on the fun even during the day!.  The costume party starts when your race starts.  You are not required to wear the costume the entire time, but the longer you wear your costume, the better chance the judges have to see it 😊  Although we encourage you to have fun, we request that you do not wear any R rated costumes, the park is still open for public use.  Come down and join us!
