Hi Karen
I always wondered what a 'good' pace was as well!!
I have been running on/off for just over a year and now regularly for 6-7 months.
I did my first ever 4 miles (the distance of the route that I take) in 41-42 minutes and that was a year ago. I am down to 4 miles in 30-32 minutes, depending on how I am feeling.
Like Nick, except that I am female, 32 years old and of average fitness (bleep test score averaging 9.6), that means I also do approximately 8 minutes per mile. I did 6 miles the other day in 49 minutes but I think I would be slower on a longer runs.
I can't keep up with the stronger runners at my running club, and I am always a little behind them, but I don't think I am the slowest in our group.
Hope that helps.
Angela
