Is this macro posible?

Can't test this myself at the moment but try this:

/automove on
/ac "Sprint" <me>

I love you! Thank you so much.

And I think you can use "/echo" to make the macro loop.
Something like
/echo (name of your sprint macro)
at the end.

Somebody correct me if I'm wrong.

No, /echo displays a message that only you can read. That's what people use after a loop to know that the loop is over.
To loop it, you use /wait <time>

The macro ended up like this:

/macroicon Sprint
/automove on
/ac "Sprint" <me>
/wait 30
/ac "Sprint" <me>


That makes it wait 30 seconds for Sprint to cooldown and then casts it again while you're still automoving. I only use it twice because I doubt I'll be running longer than a minute.
