Outer race of sealed cartridge bearing stuck in hub

No, there is 0% purchase on the race. I tried wedging a flat head in from the stuck side, trying to flip it out but as the point of leverage is on the actual race itself all I got was a load of sparks.

I don't have a dremel, and as it's my beater and I'm about to go on holiday on monday, I'd like to avoid spending £50 on a tool, even if I will use it in the future. Don't know anyone to borrow one off either, already asked likely candidates!

Can you not get a screwdriver to connect with the race at all or just a little bit?

If it comes to it, you could cut a couple of slits in the outer race with a dremel or something and then get medieval on the motherscrubber.
