No way I'm ready to race in 3 weeks!
Singapore could be interesting...
I'm also liking that Medoc Marathon suggestion from a prior post. Running + Food + Wine = ^ Mix in a few days in the French countryside - that does not suck.
In Medoc, they give you something like seven hours to finish it. So clearly a lot of the emphasis is on sampling local products along the way.

It's not like you have to be something silly like a "marathon runner" to enter that one.
