I haven't run Big Sur, but I think the scenery would be worth the trip.

I have not run this one, but I really want to, and probably will in 2015. I've heard it's extremely hilly.

I'm also interested in running Surf City in southern CA, but I know I won't be in 2015--I have too many other things going on to make that trip this year.

The Rock n roll half in Las Vegas was on the strip at night...it was pretty cool

Iceland in August.

Runner's World runs regular articles on great halfs.

Just google 'best half-marathons in ___'

There are tons of lists. New Orleans looks pretty sweet.

Now that I'm seriously getting more into running and am almost half ready, are there any especially fun/beautiful/exciting/etc half marathons that are worth making a trip out of? Outside of the local area?
