Expect your respiratory rate and heart rate to be a little higher, that's just our bodies' normal response to lower levels of oxygen in our blood. Take it easy for a day or two before exerting yourself excessively. You'll want to drink lots more water when you get up here. If you drink alcohol, expect it to affect you more at altitude. Enjoy your stay.

Best answer. My home is at 6000ft, just east of Denver. I have sarcoidosis in my lungs and while I get out of breath with over-exertion I do just fine. In fact, next weekend am of up to Ridgway State Park near Ouray. No big deal - even taking the bikes. :)
As 2milesup says, take it easy for a couple of days, drink plenty of water and have fun.
