Course distance? Elevation profile? How many corners? Any idea of what the field is like? How comfortable are you at high cadences for long periods of time?
I've run between 72-84 inches but the races around here generally aren't flat. For a flat crit gearing recommendations are generally around 48/15 or 48/14 but these are usually for roadies who never spin above 100 rpm. If you're coming from a road-fixed or track background something with a little more spin will generally suit you better. 48/16 or 46/15 is what I'd recommend as a general gearing if I had no info about the race.
There's going to be a lot of speed delta going on so you need to have a gear you can spin up really well but still accelerate efficiently out of the corners or when making a jump.

I'd think I'd want to aim for around 100 average cadence. I've had 48x15 on all winter so feel pretty comfortable there. Might bump up to 50x15, or 48x14. I've noticed I have slower acceleration compared to other fixies at stop lights commuting, but bomb past them as I get into their draft- thats not a race though.

do you mean to say that you can avg 26mph for 30+ min by yourself?

Fresh Garbage
Have you ever raced a crit? Drafting at those speeds isnt that hard until you have to corner and deal with the accordion effect.
