Hey Running Mommy,
When you do your IM, they're gonna throw you out in traffic, so you may as well get comfortable with it now so you aren't all fearful during your race.
I used to be scared like crazy riding without a bike lane- now I still don't like it on some roads, but on others, further out, people aren't in such a hurry and they move over into the whole other lane. Now I really only get nervous when there is traffic from both directions and the car behind you won't move over because of oncoming traffic.
Seems like drivers are worse-behaved in the afternoon/evening, too, so you could go on your adventure very early Saturday or Sunday until you were more comfortable with the route.
Like others have said- I worry less if I feel really visible. Get a dayglow vest and one of those 10 LED tail lights- they are only about $30 or something, and last 100 hours!! I used mine during the day last Sunday, since I had noticed on a brevet that a lot of people used them during the day, and they really _were_ visible- same thing for vests.
Hey, another thing, I think, if a driver moves way over and even slows down a bit, wave at them to thank them for their consideration! That way they _know_ you appreciated their thoughtfulness and will be more likely to behave that way the next time.
Nanci
