Stick with it!! Go back every week, and be tenacious! You might get dropped over and over, but there will come a day when you hang on the whole time. Then the day will come that you start to feel "hemmed in" by that group, and you'll be eyeing the A group.

One of the best ways to get better is to ride with people that are faster than you. I did it last summer- I started going to a 40 mile ride that's frequented by alot of men who race, and was dropped over and over and over. Each time, I was able to hold on a little longer. Now, I don't get dropped... In fact, I attack the guys in a couple of spots! Just don't give up!
