Boy does this resonate! Did my first group ride last weekend, and ended up tumbling into a pond because the group was going WAY slow, I was riding between the group and the concrete curb around that body of water and I slowly got squeezed towards it. All of a sudden I had a choice of powering up and knocking someone else down or try and skim along that curb, and the skimming didn't work and I was too slow to stop and put a foot down and tumble I did. Got a few scraps and bumps, no serious rash as it WAS in water I tumbled.

You can bet I will be much more situationally aware the next time! And maybe not pay as close attention to the very pretty fellow cyclist I was chatting with at the time... she probably would have eaten some pavement if I powered up to stay up!
