Ian, you rode really well and it showed. You demonstrated all the characteristics that we look for when bumping a rider (smoothness, predictability, good decision making, good body position, good lines and speed). There are some riders out there that think speed is the most important aspect, but I can tell you it is probably the last. Don't get me wrong, it is important, but not the most important.
I'm also glad you were able to ride with Brian and help him lower his own lap times running with you! Enjoy the Intermediate group while you can, because it won't take long for you to be at the next level!
