Hot air is less dense, thus planes generate less lift, which requires a higher speed for takeoff at the same weight. Higher speed means longer runway requirements. Combine that with being in DEN, which is 1 mile high anyway and thus less dense air to begin with, and you wind up with a double-whammy.

The other thing, which I only know tiny bits about, is that it may not even matter how much runway is required. It could be some other limitation where a plane is not certified to operate in certain conditions. For example, if the required takeoff speed is too high in certain conditions, the tire rotation speeds may exceed what the plane is certified for, and that could cause risks of tire failure on takeoff, which presents all sorts of problems in its own right.
So, if that was case, it wouldn't matter if you had a 200,000-foot runway, as that's not the limiting factor.
