Hi OKC:

Glad you had a successful hunt!

The water is most important. However, 3 miin 40 min is not even getting close to anaerobic excercise, which is what you need. 3 mi in 20 min would bebetter. You probably got in much better shape than you were, but, you now know what altitude does to the body.

I would do short bursts (e.g. windsprints), resting as needed, rather than waste your time on "garbage miles" that really aren't helping you beyond a certain point.

Also, remember, it doesn't matter how much work you have done at sea level, going to 9k' is going to be an adjustment for anyone.

Good luck,
CE
