Raidho is the letter R

Anglo-Saxon rune poem (from ragweedforge.com)

Riding seems easy to every warrior while he is indoors
and very courageous to him who traverses the high-roadson the back of a stout horse

Raidho indicates that today will be a day of action, planning, and traveling about. Doors and roads will be opened, to help one achieve what is desired. It doesn’t necessarily indicate a fast paced day, but there will definitely be things going on. It will help if you can be orderly, organized and directed with it, but it’s not a requirement.
