I agree with Linda.  Two months is a good deal of time to get back on schedule with the program.  Most importantly, the race will be motivating and encouraging to continue your efforts.  You will be fine and probably do much better than expected. 

Best of luck and many happy miles!

Here is a great plan that is 8 weeks in duration: http://www.halhigdon.com/5K%20Training/5-Knovice.htm

Hal Higdon is quite knowledgeable and his advice is great.

Good Luck!

It's great that you set a concrete goal for yourself, that really is the way to stay on track.  I started running on Valentine's Day last year and I ran my first 5K in late March.  I wasn't quite done with the C25K, but I was able to run the whole thing (albeit slowly) and the motivation of having that goal kept me going during the difficult stretches in the program.  My other advice would be to tell people that you registered.  Letting other people in on your goals can be a great motivator.  Best of luck to you!
