Please remember you will need your own tracking device (or borrowed) or you will need to rent a device for the race. 

*Course update for 2025*

Williams Creek cutoff will move to 10:15am. Carson and all other cutoffs will remain the same. This is in response to our increase numbers and bottlenecking up Alpine. We hear the requests for a little extra time in that section. To complete the course within 16 hours, the remaining cutoffs will stay as is. Please let us know if you have any questions !​

We have partnered with Run Square this year to provide a common place for runners to find pacers or pacers to find runners who need pacers, arrange ride shares, offer or seek accommodations and more.
