how long interconnect for MM cart?

I just got a preamp unit that has an included phono section. But the problem is, now the connects from my turntable are not long enough to reach, and I really would like to avoid having to move the tt from where it is now (solid shelf, away from the speakers).

If I use a MM cartridge, can I run 2.5 meter interconnects from the table to the preamp? The run right now is about 1 meter. I have a run of wireworld oasis that I would have my local shop install.

BTW: cartridge Grado Red, BAT vk3i preamp w/phono.

Would appreciate any advice about how I could pull this off. My turntable is in the middle of my "vinyl station": 2 large bookshelves of LP's, nitty gritty and turntable right in between them. Really don't want to have to break up that little nook!

You also have to think about the capacitance of the cable.
Typical ballpark figure is 100pF/metre, so 2.5 metres will give you 250pF in addition to that of the Phono stage and the tonearm leads.

The ideal loading capacitance for an MM cartridge is 250pF, so the interconnect should be kept short.
