Today is a rest day, so I'm taking it easy. I plan to swim a few laps over the weekend, and my next scheduled run is on Monday. I'm not feeling ready to do 5k yet, but I know that my fitness is constantly improving (even if it's only by small amounts).

When September 12th rolls around, I'll do the 5k at whatever pace I'm up to at that point (ie: there will be walking involved).  I'm pretty sure I'll be up to 6:1 by then - 6 minutes running to 1 minute walking.
