I used to spend my summers in Santa Fe at 7,000. I would notice the difference but could still ride at a somewhat slower pace, especially on hills. It was when I got up to 10,000 and above that I really noticed it.
But 5,000 ft is about the same as hiking to the higher mountains in the southeast as well as the Adirondacks and New England, and I never noticed the altitude in those cases.
