Cutoffs and Relentless Forward Progress

Know your race's two cutoffs

There are two kinds of cutoff. The first is the overall finish limit. Western States gives 30 hours from a 5:00 a.m. start¹². Hardrock gives 48 hours for 101.8 miles with 33,441 feet of climbing³. Leadville gives under 30 hours from a 4:00 a.m. start⁴⁵.

The second kind is the intermediate cutoff at the aid stations, and the number to plan around is the time you leave. Western States says its cutoffs are the deadlines for leaving the aid station and that a runner who returns to one after the cutoff is pulled from the run⁶. Hardrock's manual says to leave each aid station by the posted cutoff time⁷. A stop that runs long can cost you the race as surely as arriving late. Leadville has cutoffs at Hope Pass and at Winfield, the turnaround, and its miles and times differ between the 2024 guide and the 2026 schedule, so use only your own year's schedule⁴⁵.

Western States lists a leave-by time for 19 aid stations. Counted from the start and divided by distance, they work out to about 18 minutes per mile all the way: Duncan Canyon (mile 24.4) is 7.5 hours in, Foresthill (mile 62) is 18.75 hours in, Rucky Chucky (mile 78) is 24 hours in and Placer High School (mile 100.2) is 30 hours in⁶. The same table gives an estimated arrival time for a 30-hour runner at each station. Against that column the margin to the cutoff is 75 minutes at Duncan Canyon, 60 at Foresthill and at Rucky Chucky, 25 at Pointed Rocks (mile 94.3) and none at the finish. The race says its cutoffs are not a pacing guide, that slower runners should focus on the 30-hour time and not the cutoff time, and that a runner close to the cutoffs is in trouble⁶². So plan against the race's own estimated times, and treat the cutoff column as the edge you do not want to see.

Know where your race's hard gates are before you start. Leadville's Hope Pass and Winfield cutoffs and Western States' Foresthill cutoff are examples. Heat is not a cutoff, but it moves your times: the Western States page says its estimated times may vary significantly with temperature and humidity in the canyons⁶.

Build a time budget

A time budget is a plan for where your hours go. Work back from the cutoff, leave a cushion, and do not plan to arrive exactly on the deadline. Estimate each leg by time and not by distance, allowing for how deep into the race it falls, the climbing, the terrain and the heat.

Plan to slow down, and start patiently. Across 3,837 Western States finishers from 2006 to 2023, the trend was toward positive pacing (slowing) even though the course is mostly downhill, and men slowed more than women⁸. In public results from six 161 km races, runners generally spent the same share of their total time in each segment whatever their finishing place, and later finishers often ran proportionally faster at the start⁹. These are associations in finishers, so they show how races unfold and not what effort to aim for. Pace the early hours by effort, let the downhills roll at a controlled effort and hold back on the climbs. The guide on race-day pacing covers the start.

Aid-station minutes add up. Five minutes at each of the 19 stations in Western States' cutoff table is 95 minutes⁶. Know what you need before you arrive and do it quickly, and give every stop a time limit. The crew and pacers guide covers aid-station routines.

Keep moving

Relentless forward progress means you keep moving, walking included. Stopped time is the one thing the cutoff clock gives you nothing back for, so slow down before you stop. Hike the steep climbs, and budget your time with hiking pace on them.

Deciding whether to stop

Expect trouble to come. In an analysis of 25 hundred-mile races in 2023, the average DNF rate was 38%¹⁰. The most common trouble is the stomach. In a 2009 survey of runners in the Western States and Vermont 100, nausea or vomiting was the main reason non-finishers gave for dropping out (23.0%), and it hurt the race of 36.8% of finishers and 39.6% of non-finishers¹¹. So nausea alone does not decide a race. In two 2026 surveys of endurance athletes, 230 ultra-trail runners and 497 athletes across endurance sports, stomach symptoms in competition were about four times as likely after stomach symptoms in training, and withdrawing for stomach reasons about seven times as likely after stomach symptoms in competition¹². Fix your stomach in training, as in the guide on training your gut.

Make the decision in a few steps. Do not decide in a dark hole between aid stations; tell yourself you will decide at the next one. Slow down, cool off and eat before you decide, because judgment is clouded when you are under-fueled and tired, and bad patches rarely only get worse. At the aid station, deal with what you can fix (food, fluid, feet) before you make the call. Time at the aid station counts against the cutoff, so how long you stay is part of the decision.

Settle the larger question before race day: are you willing to use every minute the race gives you to fix a problem and stay in? For a slower runner, running out of time while trying is better than giving up before trying, and for some runners with a time goal the answer is no. An injury that is getting worse, a medical problem or a cutoff you cannot make are reasons to stop, and if a medical professional at the race tells you to withdraw, do it. The guide on race psychology has more.

The back half

Expect a deep low in the back half and decide in advance what you will do: shrink your focus to the next aid station or the next few minutes, carry a plain mantra that you have used in training, and aim for the next landmark. If it is a night low, getting to sunrise is a real goal; the guide on night running covers the small hours.
