This lists most items/abilities/spells/songs that offer changes in run speed. This information is accurate to the best of my knowledge and searches. I see the question posed often and thought I would make a comprehensive list. I didn't include items that have spell effects you can cast (ie shammie boots that cast sow). I bear no responsibility for any changes or nerfs after this post.
