There are no refunds for the Butte 100, Butte 50 and Sorini 25. However, we offer deferrals. If you can't race after registering, you have the opportunity to defer your race registration for the next year for a $20 dollar deferral fee. Deferrals will not be accepted within 35 days of the event. Please note: if you choose to defer to the Butte 100 or Butte 50 up from Sorini 25 or up from 50 to 100 race you will have to pay the difference in race fees. You will not receive a refund if you defer to a lower cost event from a higher cost event. Also, in the event that race fees increase the following year, you may have to pay the difference from the previous year to current year. Your deferral can only be used for the following year. You will have the opportunity to register early the following race year. However, if you wait past the window of early registration and the race fills, then you will have to use your deferral on the waitlist and will not be guaranteed entry.
