Oddly, there are quite a few similarities between hunting spring gobblers and bull elk. Imagine hunting a 500lb turkey, great eyesight, with the ears and nose of a whitetail deer... maybe better. Elk are a blast, but a tough animal to hunt. I've said it before, but you absolutely cannot work out enough for your Colorado hunt. I hope you've been doing so all summer at least. Good luck. Let us know how you do.
