afterthoughts from my first group ride

So I did a group ride today and I didn't really enjoy. Not only that the leader took off without waiting, they were riding really fast. I like to ride fast, but I still need to ride within my limit. I had to push my skill level and my bike to follow them. My 500cc bike was no match to the guys' litre bikes. They have twice the horsepower and half the brain. I am not riding with them again.
