Some guys use tinder just for logistics but you gotta feel it out - I've noticed with some girls they need some simple chit chat over an extended period of time to build a certain rapport until they will meet.
In this case she's re-enganging and wants to talk to build a little bit of rapport. I'd let her do the talking by going "wyd" or some simple banter like "just got back from a run. it's hot out!"
On another note, why are you setting a date for 4 days in advance? girls can't keep a schedule like that. set the date either tomorrow or the day after tomorrow (and that's pushing it!) If she gives a time when she'll be free 4 days from now tentatively set up something to do "later on in the day" and then hit her up the day before to remind her (because she forgot) and nail down specifics.
