Quick answers
raceindex.org has a GPS course file for Kettle Moraine 100 Endurance Runs Ultramarathon, so runners can inspect the route line on the map. Elevation charts and ascent figures appear only when that file includes usable elevation data.
The Kettle Moraine 100 Endurance Runs Ultramarathon route has 1,034 m of ascent, 1,034 m of descent and an estimated 0.6% grade-adjusted pace penalty versus a flat route.
The Kettle Moraine 100 Endurance Runs Ultramarathon route starts at Nordic Trailhead, Kettle Moraine State Forest, La Grange, Wisconsin (100 Mile and 100K start 7 am) and finishes at Nordic Trailhead. Underfoot, expect almost entirely trail except for a couple hundred feet of road crossings. It passes Ice Age Trail, Nordic Trailhead, Bluff aid station, Highway 12 and Rice Lake. 21 staffed aid stations and 8 unstaffed water stops along the course.
Drop bags limited to 12 x 12 x 36 inches and 15 pounds or lighter. 21. Pacers allowed after 6:30 pm for the 100 Mile (at Bluff, Nordic, Hwy 12, Rice Lake); no pacers in the 50K or 38 Mile Fun Run.
The stored route produces 1,034 m of ascent, while a source states 2,682 m. GPS sampling and elevation models can produce different totals, so both are labelled rather than combined.
Its normalised GAP factor is 0.6% slower than a flat course, with about 1034 m of total ascent.
