Sasha, I'm going to have to disagree with some of your reasoning on altitude training, but I will agree with what you said about lowering the intensity and mileage
IF you are not prepared adequately for the increase in altitude.
A short stint (less than a week) at a higher altitude will bring about as much improvement as adding a week of bowling to your workouts, BUT it if you are smart about the training it won't hurt much either. If anything, the mere psychological boost of being at a camp, with little distractions, and with other runners will be helpful to most people.
I did a review of altitude training studies this past fall, here's a table I included (it doesn't come out well on here):
LH & TH refers to living high and training high (all training and living is done within this altitude)
LH & TL refers to living high and training low (mixed training; most fast training done at lower elevations/sea level)
LH & TL supplemental refers to artificial means (table shows required evelation settings needed for response)
Comparison of Altitude Training Methods Required Elevation(s) Duration at Elevation Performance Increase*2 LH & TH Greater than 2500 m > 4 weeks, with daily No significant
or 8200 ft continual hypoxic exposure improvement
LH & TL 2000-2500 m > 4 weeks with daily hypoxic Average 1% increase 1
or 6500-8200 ft exposure of 22 hrs or about 13.4 s,
LH & TL 2500-3000 m > 4 weeks with daily hypoxic Average 2% increase
Supplemental*1 or 8200-9800 ft exposure of 12-16 hrs
*1 (by artificial means, including altitude tents, hypoxic chambers)
*2 (between 5000 m time trials before and after 4 weeks exposure in well-trained runners)

So really, for any positive or negative problems to occur, you would have to be up there for a while. A week isn't going to help or hurt much running wise unless you do something extremely out of the ordinary. Sorry to hijack this thread for a minute, but I don't want people getting scared to go to this camp. Just be smart.
