Quick answers
raceindex.org has a GPS course file for The Hawk Hundred (Lawrence) Marathon, 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 The Hawk Hundred (Lawrence) Marathon route has 495 m of ascent, 487 m of descent and an estimated 1.9% grade-adjusted pace penalty versus a flat route.
The The Hawk Hundred (Lawrence) Marathon route starts at Clinton State Park, Shelter 1 / Overlook Park, 798 N 1402 Rd, Lawrence, KS 66049 and finishes at Clinton State Park, Lawrence, KS (same Start/Finish HQ as the start). Underfoot, expect technical rolling singletrack trail through Clinton State Park, including a scenic shoreline red-blazed section, the Cactus Ridge section and a 2.5-mile loop with two ascents of Bunker Hill. It passes Clinton Lake shoreline, Sanders Mound, Land's End, Cactus Ridge and Bunker Hill. Three distances (100 mile, 50 mile and marathon) run on the same 25-mile loop.
Drop bags allowed at the Land's End, West Park Road and Start/Finish aid stations; crew access at West Park Road and Start/Finish. Pacers are permitted for the ultra distances under the Lawrence Trail Hawks race rules.
The stored route produces 495 m of ascent, while a source states 640 m. GPS sampling and elevation models can produce different totals, so both are labelled rather than combined.
Its normalised GAP factor is 1.9% slower than a flat course, with about 495 m of total ascent.
