I don't think the consistent effort theory applies to this race. Smart racing involves an understanding of pace variances over undulating terrain. On the mountain, it's just a straight climb and a straight descent. The consistency loses its value rather quickly once you start heading toward the sky. There's no way around it: Pikes Peak Marathon (and Ascent) is going to hurt if you want the clock's respect. Just keep in mind that regardless of your level of effort at 10-13,000 ft, your body can only do so much based on your training and acclimation. But also keep in mind that it's a lot easier to run downhill than up! Experiment with running at 10-15% incline on a treadmill for various amounts of time (even if you live in an area with good hills) to test your response.
