Course line from the race's own GPX. Source file.

Multi-loop trail race on the Clinton Lake North Shore Trails: a 25-mile lap (blue, red and white blazed singletrack, plus the grass Bunker Hill/Goodwin Loop off West Park Road) repeated from a single Start/Finish.

The race

What this one is

A multi-loop trail race at Clinton Lake State Park in Lawrence, Kansas, presented by the Lawrence Trail Hawks. Offers 100-mile, 50-mile and marathon distances, all run on repeats of the same 25-mile North Shore Trails loop from one Start/Finish.

Run annually since 2011; the 2026 edition is the race's 16th running. A 75-mile option offered in at least 2025 is not offered in 2026 (2026 UltraSignup and club pages list only 100 Mile, 50 Mile and Marathon).

Crew rules
Crews may meet runners at Start/Finish HQ (free Army Corps of Engineers entrance, gate locked 10 PM–6 AM) and at the West Park Road aid station (inside the fee area of the state park: $5/vehicle day pass or $25 annual permit required to drive in). Lands End is not a crew-access station even though it is reachable by vehicle via Campground 1. trailhawks.com
Pacer rules
One pacer at a time. Pacers join at mile 50 or later, from either Start/Finish or West Park Road. Free pacer registration on UltraSignup or race day; must check in at Start/Finish for a bib. Muling forbidden.
Drop bag rules
All three aid stations accept drop bags. Bags must be dropped 15 minutes before the runner's own scheduled start time; keep bags a reasonable size, marked with name/bib/distance/station. Bags are returned to Start/Finish HQ by 12 pm Sunday; unclaimed items are donated. trailhawks.com
Cutoff philosophy
Cutoffs are set at the two final-lap aid stations (West Park Road, Sunday 10 AM; Lands End, Sunday noon) and the finish (Sunday 2 PM, 32 hours after the 6 AM start). Volunteers break down and depart at each cutoff; runners who continue past a cutoff on their own can still finish but are not eligible for finisher awards unless they reach the finish by 2 PM. hawkhundred.com
