Probably a statement people should really think about. Speaking from experience many moons ago when I first started riding in our medium-fast and fast groups. If you are thinking about it you probably don't belong in the fast group. These people already know. Durk is downplaying his normal pace - dude can ride. Just be aware it can get quick BUT they will always wait for you so do not feel the need to try and play catch up.
I was so bad on my first fast ride they assigned me a sweeper (Thanks Jerry and Dave I still remember this day like the back of my hand. It's the day I decided to take this sport more seriously- I think I've gotten out of hand at this point.)
I still remember the days of watching Doc, Paul, Jerry, Jim, Uncle Punk, Tony, Dave, Derek, etc just disappearing into the distance . They made me better.
