Friday Open Thread: Destination races — where do you dream of running, how do you choose?

How do you pick the destination races you want to run? Are you looking for a particular challenge (like Hawaii’s Xterra Trail Race) or are you looking for a place you’d love to visit, that also happens to have a race you can run while you’re there? Or do you build your vacations around races? What have you learned from those you’ve run? Inquiring minds (like me!) would love to hear from you. —Terrell

Runners at the Dubrovnik Half Marathon make their way along the Walls of Dubrovnik, a series of stone walls built around the southern Croatian city in the 7th century.
