The Jack & Jill's Downhill Marathon & Half route starts at Hyak Sno-Park, Snoqualmie Pass and finishes at North Bend, WA (finish area at 44701 SE North Bend Way). Underfoot, expect smooth, hard-packed gravel rail trail. It passes Snoqualmie Tunnel, Palouse to Cascades Trail and rail-trail trestle bridges. post-race shuttle returns runners from the North Bend finish to the Hyak start parking.
The stored route produces 783 m of ascent, while a source states 81 m. GPS sampling and elevation models can produce different totals, so both are labelled rather than combined.
Its normalised GAP factor is 1.5% slower than a flat course, with about 783 m of total ascent.
