What is the optuim speed for my age

I'm swimming three times a week. The distance is one mile in 33 minutes. I feel I should be swimming faster. Is 33 min. mile slow for my age, need some feedback.:confused: If you are always swimming a mile straight 3 times a week, I think your body adjusts and gets used to the pace and keeps going at that pace. If you want to improve your time, you might want to mix your work-outs up and do some interval work. Looking at some of the work-outs on the work-out forum might help. As far as what the optimal speed is, who knows. The fact you are getting in and working out, is what is important. You should be competing against yourself, and test if you are improving your time, and your fitness level. Other factors besides speed mark this, like heart rate,the ease in which you swim the 33 minutes.
