Manage Account – Endomondo
Endomondo users sometimes accidentally create a new account instead of logging into an existing account. To check how many profiles you have on Endomondo, go to www.endomondo.com and search for your name in the box on the website's top right-hand corner.
In case you have more than one profile, please transfer your workouts to the profile you would like to keep by exporting the workout data from one profile and importing it to the other one.
Once you have moved all of your workouts as described above you can close the profile you are not going to use. Read how to do that here.
