One of my former coworkers was hit by a car while road biking almost 2 years ago. She used to have a spinning studio and ended up selling it because she was still in a lot of pain from the hit. I'm terrified of that and that's part of the reason why road biking is not really appealing to me. Well, that and the cost of buying another bike. The tri I signed up for is on backroads so I feel a little better about the biking part of it, but I'm still scared.
That's definitely a concern with road biking, unfortunately...
I do want to get a road bike at some point though, cars be damned! All I need now is more money...
