Jim in Thailand: Phuket & 1/2 Marathon

Phuket is an island about 1 1/4 hrs flight south of Bangkok. It is a beautiful place of pineapple fields, forests, small villages, lovely bays, and great beaches. It was a treat to spend a weekend there.
The reason I went (aside from some R&R) was to run in the Phuket International 1/2 Marathon. It was a great race and a lovely route.
By no plan of mine I now find myself with 1/2 marathons completed on four continents: Europe (France), Africa (South Africa), North America (Chicago, Louisville), and now Asia. Now, how do I manage races on the other three before I die?!
