There may be a fast line that isn't as bumpy, but as a track day virgin I RARELY ever rode that line. Nelson was my first track EVAR and it was in the rain. Because ofvthat i had a new found respect and confidence in my tires. Like someone said, a lot of it is mental...but it is bumpy, and for a newb T13 can be a little precarious turning out of T12 into what seems like rolling hills. With that said, you'll be in novice and though the CRs are a bit flamboyant and homoerotic...they'll take care of you on and off the track. Ask questions, hydrate, have fun out there.
