5 K time

I started running again and feel better than I have in years. I am 42 and was wondering what a good time is for running the 5k. When I first started it took me about 45 minutes. My best time now is 24 minutes. I know when I was on the track team in school 17 minutes was good but I will never see that again.
How long does it take for the average 42 year old male with heel spurs?

It depends on your level of conditioning, how much you train, and your training history. I wouldn't push trying to get your time up too quickly, especially at your age. Just take it easy and do the best you can to improve your speed.  Do a very gradual speed program. If you have access to a 'mill, you can use it for speed training as well, it will be a little easier on your joints and feet. I do all of my HIIT workouts on a treadmill but do my long runs outside. FWIW, I'm in my late 40s and my 5K time is about 25:00. But I run about 50-65 miles a week and do marathon training on a semi-regular basis. And I've been running for years. But speed work to run shorter races isn't a priority for me.

Another way to get faster at shorter distances is to increase your mileage, a la Lydiard. If you can work up to 60 or 70 miles a week, or have the desire to do it, you'll start smoking at 5K and 10K races.
