Your Login can be found on the the verification email that you get from the Running Room when you submit a Password Reset.
Here is an example:
When you have logged onto your Member Profile you can edit your login on the Profile Page.
Note: The Login cannot exceed 21 characters. If you are attempting to use an email address that exceeds the limit it will not be accepted.
We also do not allow members to share the same login. If you are updating your Profile and get an Invalid Login message you will have to select another login.
Tip - try adding some letters to the end of the login name you are selecting to make it unique. eg - jackrunner64 / 55jackrunner / jack4runners /
