To clarify, my computer is calibrated, I was doing 35 when passing the group. I did not do 35 the whole mile after passing the group. It was the fastest I've ever gone in the flats, that's why I remember it so well. I just didn't check my wheel until after a mile. When I ride on the hoods, I am pretty aero as it is, I do not sit upright. And I was toast when I stopped at the red. The group pulled up at the light, they went straight, I strategically turned left. At that point they could be going 20 and I would probably get dropped.
