I drink way too much. Does it hurt performance? Probably. Am I willing to give it up? No.
Other than that, I find cycling works the best for alpine. I run trails in Forest Park a lot, but I seem to get more benefit from cycling. If I have time, a long ride (2-3 hours) is great. But just this morning I only had an hour, so I left my house, rode downtown to the river then up as hard as I could up Vista to Council Crest them home. Hard as hell, but effective. I'll usually do that 2-4 times/week in addition to a couple of runs and of course whatever I'm doing in the mountains.
