Welcome and kudos! 
Good for you for getting back in the saddle!! You should be patting yourself on the back. I'm a new rider (just started around April or May), so compared to a lot of these ladies I'm pretty sure I'm a pokey butt, but I sure am feeling better and stronger and enjoying my rides. I finally have my ride up to 12 miles and think I avg about 12-13 mph. However, I'm in NW Florida and don't have the mtns and large hills a lot of you ladies have to cope with, so I don't know how much of an accomplishment some people here would consider that; I'm happy with it, though.
