I wanted to know if u get anything out of an easy ride. For instance i ride around a block next to my house. It is almost exactly a quarter mile around once. So today i did 10 miles worth. I was not going all out or anything. It is all flat i just did a lot of miles. So am i gaining any muscle, stamina, or endurance doing this? Am i wasting my time? It is just a quick couple loops since it is very cold in PA at this time. In otherwords is this any type of training or do i have to at lleast 25 miles around this block of mine?
