Glad I asked, because the aforementioned really bad character was really bad because they try to optimize movement, at great expense.

I don't think specific magic items are in the core books full stop. I checked the DM book and apparently a guide for making them is on page 284, where it describes the ones I would be after (something to confer the Longstrider, Jump and Haste spells) as Common, Common, and Uncommon, respectively. I asked because the speed character is basically taking 5 or 6 levels in a mage class just for those three otherwise, but it probably doesn't matter with their main gimmick being mostly irrelevant.

If PDF size is the limiting factor, I could just post the subclass I was going to use, if that's okay with you.

If it's okay, I'd use the Swashbuckler. It's a subclass for Rogue, (from Xanathar's Guide to Everything) hence all the details are on one page. The character didn't feel right in another class. (and even worse as another Rogue subclass)

Otherwise, I'll just make a new character.
