Well, we do have rides like that in my cycling club. If I know I'll get dropped, I don't go on those rides. Or, if I know I'll get dropped... I make sure I know the route back home so I'm fine on my own.

It sounds like you me that you are FAST! If I were with a group going 26 mph... well, I wouldn't have even been up there with them!

Keep at it, and maybe you will keep up with them and not get dropped at some point. Or... maybe you can find a buddy who is your speed and who will do the ride with you?
