We generally do not permit deferrals for our races. We are a small team of volunteers, and managing deferrals is difficult. Deferrals put a lot of wrinkles in regard to the amount of wasted medals and food that we purchase, and make additional administrative work for next year's races. We prefer that registrants use RunSignUp's ability to transfer registrations to other runners, which most people are able to make work. On the rare occasions when we do grant deferrals, it is only after people run out of options, and we will give preference to runners who have been with us before.
