A player in our party recently got a magic item that can boost your athletics and double your move speed once per day. I didn’t get how useful it could be until I saw him grapple an evil priest and just fucking drag him from one side of the map to the other.
Turns out grapple + double move speed + dash action is super awesome for getting enemies out of position and screwing up their formation.
I’m sure you can find more if you talk to your party members or DM though. Off the top of my head, Glamour Bards have an ability that lets the whole party move up to their movement speed as a reaction. Then there’s Haste obviously. Ask your party if they have any spells or features that can make you fast 😃
