I've seen a wide range of commentary on the effects of altitude on athletes at IMLT. This is a thread for experts to draw up a concrete protocol - not for anecdotes and conjecture. Please add other key questions that are not included.

What is the optimal strategy for arrival at altitude before the event?
Will an altitude tent help at this event? If so, how much?
Will frequent hypoxic training at altitude or with an altitude training mask help? If so, how much?
What effect will the thinner air/lower air resistance have on bike speeds?
Are there any other precautions one can take to limit the effects of altitude immediately before the race (supplements, sleep, nutrition, ect.)?
