I was hit on day 3 of my cross country tour last summer. Twas a hit and run. I was able to continue the tour after some R&R. I was lucky, in several ways.

1) I'm not dead and my injuries were relatively minor.
2) I got hit close to home which made recovery much easier.
3) My bike survived unscathed although my left rear pannier has a big tire mark on it. Ortliebs stay on even when hit by cars!
4) I was able to get back on the bike within 5 days although it was painful.

I ended up restarting the tour after 3 weeks. My journal if you want to read about it. An interesting thing about the journal is that someone who lived on the road where I was hit contacted me through my guestbook. They were curious about the large police presence on their road and found my journal when they googled the date and road name!
