I know on club rides when we have a lot of people and I get stuck in the middle I get a little nervous. You just don't know what the people around you are going to do. How would someone get experience racing in a pack prior to starting to race CAT4? Is riding with a large pack with your club good enough experience? It all sounds so exciting. I've seen some youtube videos of races and it looks pretty scary...people moving all around within the pack...but it also looks so very cool...a living, morphing entity.
