Hier werden ein paar downhill marathons in den USA diskutiert, inklusive Abschätzungen der Zeitgewinne:
"The Steamtown Marathon in Scranton, Pennsylvania, bills itself as America’s fastest midsized marathon.
According to its elevation profile, it has a net elevation drop of 955 feet. It also has a few bounces, which appear to total about 100 feet. In other words, there’s 1,055 feet of down, and 100 feet of up. Applying the same type of arithmetic we used for the Shamrock Run, the course should speed you up by about 1:35 at world-class pace,
2:25 at a 7:30 pace, and 3:10 at a 10-minute pace. Not huge, but definitely enough to be noticeable.
But the West has big hills, enabling courses with truly colossal drops. One is the Tucson Marathon, which starts at an elevation of 4,730 feet and, with only minor upgrades, descends approximately 2,150 feet. Another contender for fastest course in the West is the St. George Marathon, which drops 2,560 feet. But the steepest (and potentially fastest) of all is the now-defunct Pines to Palms Marathon in California, which virtually falls off a cliff with a total elevation loss of 4,920 feet.
In theory, descents that large should speed you up by four to eight minutes — a truly enormous assist. For Tucson, the gravity boost is almost precisely 4 minutes for 5-minute milers, 6 minutes for 7:30 milers, and 8 minutes for 10-minute milers. At St. George, it’s roughly comparable because, while that marathon has 400 more feet of downgrade, it also has one significant hill."
