When I flew to Moab for mountain biking I didn't go extremely high (maybe 5000'). I didn't really notice the altitude. I was very fit and younger then though (40-ish than 57 now).
On the Trans America we went W-E and topped out at 11,500 or so on Hoosier Pass. This was all fully loaded. I felt a bit of weakness when we first hit 5000' that lasted for a day or so and it returned each time we went another 1500' or so higher. It was not a huge deal though. I did have a bit of slight dizziness most of the time that we were much over 5000', but only when off the bike for some reason.
