Registration/Refunds Click on Links Below to Register or View Refund Policy: Register Refund Policy ML Is there a limited field for the 55k race? If so, does it normally fill up near a certain date? David Tarkalson ML, Sorry for the delay, I just saw this comment. The race filled up on December 22nd this year. Registration for the 2018 event will open November 1, 2017. Thanks. Ryan Craig If and when registrants cancel will registration open again? Thanks for your time! David Tarkalson No. The opened spots will be filled with waitlist runners. I hope this helps WG Any chance it is possible to get on a waitlist for a possible opening in the 2017 100k at this point? Racheal Zeiler Any idea what the dates are yet for 2018? I’m trying to figure out if I can run Missoula Marathon and this one. David Tarkalson July 14th Racheal Zeiler Thank you Kyle Cochrane Highly suggest this over the Missoula Marathon. Racheal Zeiler Thank you. I’m definitely signing up for this one. My sister wanted to do the MIssoula Half Marathon the next day and I figured I could just use it as active recovery but I talked her into doing Billings instead so I don’t have to do them both in the same weekend. Tee Flanagan G’morning, just curious to know the date of the 2019 100k. Thanks!
