I use this
http://www.noping.net/english/ for my speed and average when I'm done riding and I was wondering what the Watts mean. This morning I got a reading of 414 watts, but I don't have any idea what it means. I know the higher it is, the more power you put out, but whats good or bad. What is a good target to shoot for. You wouldn't try and get the highest you can, every time you ride. I use there scale for calories used up and my time and average.
I wish I could afford a power meter, but it's not in my plans at this time. I have read where the power meter really helps keep and eye on your performance, but what are you looking for, in terms of watts?
