I don't understand the rational of championships at altitude, either. For the track, I do understand holding national championships at different venues each year, it spreads the wealth. However. I think holding a national championship at an outdoor track in a known wet climate is not great policy. I know, I know. We have one "permanent" indoor velodrome in this country, VSC. We have two "temporary" covered velodromes, Lexus in Detroit and the USAC track in Colorado. Detroit is a 166, Colorado is in the stratosphere. This brings up the discussion of "needing" more permanent indoor tracks in this country, which is a can of worms. As for USAC and Senior Games championships, it's the same thing. Rain and or elevation. Is there a perfect solution? Zwift.
