Refunds & Withdrawl Options

Registration fees are generally non-refundable, except in extreme circumstances which are judged on a case-by-case basis. If you have concerns, please consider purchasing registration insurance.

You can find more information regarding refunds, withdrawals, and deferrals here.

Processing fee and applicable tax on the processing fee are non-refundable.

Most Races Sell Out Early

Once online registration closes we accept in-person registration during Saturday’s race kit pick up provided the race has not reached its capacity.

Registration Confirmation

You will receive a confirmation email from Race Roster immediately following successful registration. This email will have a link to your dashboard where you can see details of your registration. If you do not receive a confirmation email please contact us to confirm the registration.

Processing Fees

Processing fees for registration are charged by Race Roster as an additional fee on top of the registration costs. This fee and the applicable taxes charged on it are non-refundable.

Registration Insurance

In partnership with RegShield, we will be offering registration insurance as an optional add-on when you register for a race. This service can provide peace of mind that you will receive a refund if certain conditions are met. More details can be found here.

Wave Requests – Timing Requests or Friends Paired Together

Unfortunately we do not accept requests for friends to be paired together in waves or for timing purposes.

Age Group Assignments

Athletes are assigned to an age group based on their YEAR OF BIRTH.  Their age on race day is not used to assign age groups.  As an example, all athletes turning 8 this year, whether their birthday is in January or December, will participate in the 8-9 age group.  The chart below lists the age group assignment based on year of birth.

Athletes in the 3 – 5 age group must have one parent accompany them in the pool.  The adult must be within arm’s length of the athlete in the pool.

Note that due to course safety concerns, not all races will have a 14-15 year old age group available.

Unfortunately, we will not be offering the TRi YOUTH program this year.

A sample distance chart can be found on this link. If you feel your child is not ready to be in the age group based on their year of birth please contact us by email prior to registering.
