All participants must have a one-day USA Triathlon (USAT) membership ($15) or an annual membership.
Annual and one day memberships are available to purchase during the registration process. We verify annual memberships through integration with USAT as part of the registration process. Memberships are purchased directly through USAT and only refundable through USAT.
There will be no refunds issued for the Sebago Lake Triathlon unless you have a refundable entry. Please click here to read the full refund policy.
While we try very hard to accommodate everyone’s shirt size, regardless of when they register, and do the best we can. In order to offer a fair system for distributing race shirts, the following policy is in effect: Athletes that register within three weeks of the race are not guaranteed their t-shirt size. They may choose from all remaining sizes after the race. If you register in the last few weeks before the race, we may not be able to guarantee a T-shirt. If you want to be guaranteed a t-shirt size, please register early!
