If you want to delete a rune page, you can do so from your collection screen. 1. Click on the “Collection” tab (the backpack icon). 2. Select “Runes.” 3. Open the page you want to remove, then press the bin icon. This button is also available on the rune editing screen in champion select. 4. Alternatively, you can push the bin tab on the rune menu to remove pages directly from the list by clicking on the page.
