First, confirm you are logged in to your account. Log out of the account you are currently in, then log in using the same method you used to create your account, either Google sign-in or traditional username and password.
On Track Club, accounts created through Google sign-in and traditional username and password are not linked if the same email address is used. If you create an account with a username and password, but then click “Continue with Google” on the sign-in page, you have created a second account. Likewise, if you create an account by clicking “Continue with Google”, but then log in with your username and password, you have created a second account.
If you find you have accidentally created two Track Club accounts, you can deactivate the unwanted account by logging in, navigating to Account Settings and clicking “Deactivate” at the bottom of the page.
