Registration opens:  December 14, 2019 at 12:00 a.m. (mountain time)

As of March 19, there are 33 spots left in the women’s race.  Because of the uncertainty of this event happening due to the Covid-19 virus, we are opening these last 33 spots on a women’s waitlist.  If you are the first 33 women on this waitlist you will get a spot if the race happens. You will not be charged unless the race takes place. At this point we are waiting to see where things go with the current restrictions and management of this virus.  We will be looking to make a solid decision by May 1, 2020.
