There's a lot you can do if you're smart. Sometimes things don't mesh up but for the most part they will.
That is a good point, sir. Aside from the obvious concerns about location, I guess right now I'm just trying to figure out how I'll be able to effectively balance the training cycle with orienteering/running-specific training. Perhaps I'm overthinking things, especially since this is still a few years away, but it seems like it will be difficult to maintain (and improve upon) a high level of fitness with all the time that's spent out in the field.
I wouldn't worry about it as much right now, but I can shed some light on what I've learned when we run into each other again. Keep the goal alive and train for it. Worry about what comes next a little later. Keep up the good work. Try to relax an not let the nerves get you too hyped for your next races.
Your fire to go after WOC is awesome. There are some other good goal races, too (NAOC, Mil Champs). Think of it as a very long-term (ie multiple years....5 or more) training campaign, with goals and methods that adjust to suit your availability.
