After these dates, entry fees are non-refundable (no exceptions). All entries are still non-transferable. We do have a long wait list, so if for any reason you decide not to do the race, please e-mail us ASAP so we can give someone else your spot.
Withdraws from Wait List
If you need to withdraw from the wait list, no charges will be applied to you. Please, however, let us know if you do decide to drop for the wait list.
Options if wait-listed and receive a racers slot
If you receive the opportunity to move from the wait list to the race roster, you will not be charged the entry fee until we have confirmation you still want the slot. If you choose not to accept the race slot and withdraw, no charges will be applied and your slot will be offered to the next individual on the wait-list. Prior to race week, you will have 48 hours to make your decision to withdraw or to be added to the race roster and be charged the entry fee. During race week, a decision is needed on the spot.  

There are actually four different wait-lists: one for each subdivision (ski, bike and run) and a fourth general "after lottery" list for those who registered after the lottery was completed. Here is how the wait-list system works. If someone drops from the roster, say a skier, then he or she will be replaced by the top person from the appropriate subdivision (skier) wait-list. This process will continue until that subdivision's wait-list has been exhausted. If this occurs, then someone will be chosen from one of the other two subdivision wait-lists (in this case, bike or run). If more than one subdivision wait-list remains then replacement selection will alternate. But, you over detailed people ask, what list do you choose from first? For the sake of fairness, let's say that in even years we'll select from the biker list first, or from the skier list if the biker list was depleted first.  In odd years, we'll select from the runner list first, or the skier list if the runner list was depleted first.  Only in the unlikely event that all registrants from all three “pre-lottery” subdivision wait-lists have been run through will people will be added to the roster from the fourth “after lottery” wait-list.
