Some small percentage of people will have significant problems at altitude, I think it's around 10%
Golden is around 5,200 feet, and typically that altitude won't cause problems. But some of the riding could be to 11,000 feet. and may cause pretty serious problems.

It isn't a joke and you can't just tough it out.
If you are coming from the lowlands and don't know how you will react, it's best to be cautious. Do some reading to prepare.
When I was a kid (17 and pretty fit) I came from TN to Pueblo, CO (lower than Golden) then drove up Pikes Peak (14,000+). I could not drive down, I was barely conscious after 10 minutes at the top - seriously. My mother had to drive me down.
