Everyone's reaction is different, but I do okay going from sea level up to 5000 feet. The altitude starts hitting me around 7000'.
As others have recommended, be sure to take it easy for the first few days. My worst day is the day after arrival, so I know to do just easy rides then.
Pay attention to perceived effort. If it feels high, go easy or shorten the ride.
When you feel stronger, you can start riding longer and faster. And hydrate more than you normally do. Altitude sucks the fluids from your bloodstream.
