Hey Comprido, welcome to LRH
I have been hunting in Colorado since the early 70's
Got to eat my share of elk too, that does not mean every year.
Your biggest challenge may be getting a license to hunt out here
and finding the time to use it. Being accurate with your rifle to at least 300 yards
wouldn't hurt either. Then there is the physical fitness thing...
I think you still can get a bull elk license in Colorado.
Please don't expect to shoot your perfect bull your first time out. It could happen but it's unlikely. Finding elk is a long process. Having a guide, or friends who live in your hunting area is a BIG help. So go for it. Maybe you can meet some people out here and improve your chances for next year.
