    Hi there! Any idea when regular registration for the 2016 race will open?


    • Jenny says:

      Hi Joseph – Sorry I didn’t see your note earlier. We are planning to open registration the first week in April. We will have a one-day early bird sign up with a $10 discount at The PULSE on State St in Boise. In-store early bird special only. It will probably be the day before we actually open registration. You can follow the FB page or the website. Thanks! – Jenny

    This is a terrific event!! I would have enjoyed it 65 years ago when I was the same age as the younger runners. HOWEVER, I want to warn everyone that there is a real class runner in your midst – Pat Honsinger – my grandson. Have a wonderful time and, hopefully, noone will require the Aid Station!

    • Jenny says:

      Hi Stephen,
      Thanks for your kind comment. Your grandson did an outstanding job! We were lucky to have a beautiful day!

    Does anyone have a Garmin file for the course?

    • Jenny says:

      Hey Jennifer – Here is the course from my Garmin. Don’t pay attention to the mile splits – I ran the course and was writing down every place on the course where anyone could get confused. I gave the notes to the folks who marked the course for me so that they could place “Do Not Cross” tape on places where I didn’t want people to go. So don’t be afraid of how long it took us to run it. It won’t take you this long 😉 Feel free to let me know if you have any questions.

    Hello Jenny,

    Have I told you lately that you rock? You are putting on a 1st class event and I can’t wait for the weekend. Thank you so much for all of your extra assistance! That map is of great help for us guys. (its all about the visual) We never read instructions lol! See you Saturday.

    • Jenny says:

      Hahaha! Thanks, Tom! You’ll have so many course markings out there – only way you could get lost is if you run blindfolded! See you Saturday!

    What a great event You are the best Jenny… Hey, by the way, do you know what happened to the Course Map the actual course map with the highlighted route. It seems to be missing and was posted earlier. (you do have the course map with every trail but not the one that you highlighted the course.) If you can find that again that would be great. thanks so much and see you Saturday

    • Jenny says:

      Thanks, Tom. I took the marked course map down temporarily because we moved the aid station locations, and I didn’t want anyone getting confused. It’s back up now with the correct aid stations. However, the written instructions at the bottom of the page may be a bit easier to follow because the map is sort of small. Hope this helps. See you on Saturday!
