this brings back memories from the late 90's... each Thursday, he and about 20 others would routinely show up at the "incline" of manitou springs (only the wooden planks are left) and run/hike up a very steep grade to an overlook terrace and then return via the Barr Trail. His website, still active after all these years:
www.skyrunner.com . On other days, he would drive up the pike's peak road to a parking spot at 12,500 feet, and go for a long run on a relatively flat terrain above timberline. Not sure if he was charged the $10 that the toll booth charges, maybe he had a "season pass"...
