By next weekend you'll be at the end of the 3rd week of C25K, which is a 23 min mixture of walking, jogging and running. I don't know your current speed, but if you were to do that mixture (per the C25K plan) for the length of the 5K, you should finish in good shape. Just don't try to run the whole thing unless you've been doing other aerobic exercise on the side - especially if you're signing up to do the race with others who are running it.
