I've never used the freewheel side. 46t on the front (~71gi). I'll probably ride.
You'll do fine. A varied terrain, with at least a little bit of climbing, is good on a fixed gear. You'll look forward to the opportunity to stand up and mash up a hill now and then.
My ride is going to be something like 6800 feet of climbing, so I may need the slightly lower gear. I just hope the 46/18 is low enough!
