A person with owner or administrator rights for a Strava Club can delete a group imported into the National Bike Challenge by following these steps.
1. On the NBC website, click on your name in the upper right corner. From the drop down menu, select settings. Select the word Groups on the left side of the new screen.
2. Under the groups you have imported, select the group you would like to delete. In the lower right side of the screen will be red text allowing you to delete this group. (the red text may not appear if you have multiple admins, and you did not import the group).
NOTE: Do not delete a group because you are having issues with it. This will require manual intervention by second level support to re-instate it.
