Wow, Thom, you're setting yourself up for a challenge. I have done a lot of international travel so I know jet lag. Have you traveled internationally enough to know how your body reacts? I have not run a major race that close to coming home, but have gone back to my normal training routine the day after getting back from Eastern Europe. Here are some suggestions for quick recovery. Most important is to sleep as close to your normal home schedule as possible. I force mayself back to my normal schedule and use the non-prescription Melatonin to help me get on to that schedule. Even when you're not sleeping, rest and relax. Drink a lot of water during that two day period because plane flights tend to dehydrate. I think that once you start running, you will quickly forget your jet lag if you have trained properly. Run well.
