Your First 100K, Aid Station by Aid Station

Your First 100K, Aid Station by Aid Station

Sixty-two miles is not a long marathon. It is a different sport with a different clock. The 100K is the distance where the day stops being about how fast you can run and starts being about how well you can manage — calories, cutoffs, feet, and the twelve minutes you keep giving away at every table. Do the managing right and a first 100K is one of the best days of your life. Do it wrong and you meet the cutoff clock at mile 46 with your headlamp still in a drop bag you will never reach.

So let's run one. Not a real race — a representative one, built from the parts every mountain 100K shares. Call it the Pine to Peak 100K: 62.1 miles, 11,400 feet of climbing, eight aid stations, a 4:00 a.m. start, and an 18-hour cutoff that closes the finish at 10:00 p.m. We will go through it the way you should plan it — one leg at a time, deciding what to eat, when to bank time, and what waits in each drop bag.

The Plan Before the Gun

Four numbers run your whole day. Fix them now, not at mile 40.

Pace by effort, not by watch. For a first 100K, the entire first half should feel embarrassingly easy. Hike every meaningful climb from the start — not when you get tired, from the start — and run the flats and downhills at a pace you could hold a conversation at. A 15-to-16-hour finish on this course averages under 4 mph including every stop, which sounds slow until you are doing it at hour eleven.

Fuel 200-300 calories an hour, starting early. Your stomach is fresh at mile 5 and wrecked at mile 50, so bank calories while eating is easy. Most first-timers run a liquid-plus-real-food plan: sip a carb drink mix between stations for a steady 100-200 calories, then top up with real food at the tables. The failure mode is falling behind early and never catching up.

Treat every cutoff as "out by," not "arrive by." The times posted at each station are when you must leave. Cross a mat with two minutes to spare and stop to fix your feet, and you are already out of the race. Know your out-by times cold and build margin against them early, because you will spend margin late.

Run your drop bags like a system. You get bags at three stations here. Each one is a stuff-sack — ratty, labeled with your number and the mile, packed to solve that leg's specific problem. Not luggage. Not everything you own. The one thing that leg needs.

Guard your feet from the first mile. Feet end first 100Ks far more often than fitness does. Lube your feet before the start, not at mile 30 when the damage is already under the skin, and treat the first hot spot as an emergency worth a two-minute tape job rather than a mile-50 problem worth a DNF. A wet-sock creek crossing early, fine trail dust caking onto lubed skin, a seam you never felt at marathon distance — any of it becomes a silver-dollar blister by the time the sun goes down. Every drop bag on this course carries a dry pair of socks for exactly this reason.

Here is the course. Learn the numbers, then forget the shape.

Start to Cedar Gap — Mile 0 to 6.8

You start in the dark. A 4 a.m. gun means a headlamp for the first two hours, until the sun comes up somewhere around mile 6. This is the most dangerous stretch of the race, and the danger is that you feel fantastic. Fresh legs, cool air, a conga line of headlamps up the first climb — everyone goes out too fast here. Do not. Settle into the back of your effort. If you are passing people in the first hour of a 100K, you are making a withdrawal you cannot afford.

Fuel starts now, not at mile 20. Take your first gel or a few sips of drink mix within the first 45 minutes. Cedar Gap is a water-only station — a table, some jugs, no crew, no drop bag — so you carry everything you need for the opening 14 miles. Top your flasks, grab nothing you have to chew, and keep moving. You should reach Cedar Gap around 5:20 a.m., a comfortable 55 minutes under the cutoff. Bank that margin. You will need it after dark.

Cedar Gap to Bracken Hollow — Mile 6.8 to 14.2

The sun comes up on this leg and the race feels real for the first time. Lights off, into a vest pocket. This is runnable, rolling terrain — the kind of ground where you can quietly hold pace and eat well. Keep the effort easy; the day is long and this is not where it is won.

Bracken Hollow at mile 14.2 is your first full aid station: real food, your crew, and your first drop bag. This is where the day's logistics start. Your crew has your bottles pre-filled and your fuel pre-mixed, so this is a 90-second stop, not a picnic — the entire aid-station strategy is built on not giving these minutes back. Swap empty flasks for full, grab a quartered PB&J and a boiled potato dipped in salt to eat on the way out, and go.

Your Bracken Hollow drop bag is the "settle in" bag: backup gels for the long crewless stretch ahead, a spare pair of socks if the morning dew soaked your feet, and a small tube of anti-chafe salve. Reapply the salve here — mile 14 is early enough that it heads off the mile-50 crisis. A dab of a proven anti-chafe salve now is the cheapest DNF insurance on the course. You should leave around 8 a.m., still comfortably ahead.

Bracken Hollow to Hawksbill Notch — Mile 14.2 to 22.9

Now the course shows its teeth. The climb to Hawksbill Notch — the runners call it the Staircase — is the first big vertical of the day: roughly 2,400 feet of gain packed into four miles, with a section that pitches past 18%. This is a hike. Everyone hikes it. If you brought poles, this is where they earn their place in your vest, taking load off your legs and keeping you upright on the loose steep stuff. Folding carbon Z-poles live in a vest pocket until a climb like this, then deploy in seconds — on a course with 11,400 feet of gain, they save your quads for the descents that would otherwise wreck them.

Power-hike it at an even effort, eat at the top where your heart rate drops, and understand what the Staircase does to the clock: your pace on this leg is half what it was on the last one, and that is correct. Hawksbill Notch is a full aid station but crewless — no drop bag either — so restock your own bottles from the jugs, take some real food, and keep the stop short. This is where knowing your vert pays off; if the feet-per-mile math is new to you, that is a whole separate lesson. You should crest and roll into Hawksbill around 10:15 a.m., about 45 minutes under the cutoff.

Hawksbill Notch to Coldwater Crossing — Mile 22.9 to 30.4

What goes up hands you a long descent to Coldwater Crossing. Free time, if you are smart, and quad damage, if you are not. Run the downhill relaxed and light — do not hammer it just because you can. The runners who bomb the descents at mile 25 are the ones limping at mile 50.

Coldwater Crossing at mile 30.4 is roughly halfway, and it is a big one: full aid, crew, and your second drop bag. You have been moving for six-plus hours. This is a legitimate five-minute stop, not because you are slow but because the second half of a 100K is a different race and you set it up here. Sit — briefly, with a hard time limit — and do real maintenance: check your feet properly, tape any hot spot before it becomes a blister, refill and pre-mix your fuel for the next long push. A 30-serving tub of endurance drink mix in your crew's hands means every bottle from here to the night is poured and shaken in seconds, not scooped and stirred while the clock runs.

Your Coldwater drop bag is the "reset" bag: a fresh shirt if you are salt-crusted, more calories, and a backup light in case your plans change. You should leave around 12:15 p.m., 45 minutes under cutoff. Halfway done. The day is about to get long.

Coldwater Crossing to Silverpine Meadow — Mile 30.4 to 38.2

This is the leg where the race stops being fun and starts being work — the classic afternoon low. It is hot now, you have been out for eight hours, and the terrain is a grinding series of rolling climbs with no single summit to aim at. Your stomach may turn here. This is normal, and it is a fueling problem, not a character problem.

If you cannot face another gel, switch to real food and flat cola — the deliberately de-fizzed cola on every ultra aid table is there precisely because it is easy calories when nothing else goes down. Silverpine Meadow at mile 38.2 has your crew but no drop bag, and it carries the day's tightest cutoff: OUT BY 14:30. Watch that number. If the afternoon low has eaten your margin and you arrive close to 2:30 p.m., you leave immediately — fix nothing, eat something you can carry, and move. Silverpine is where first-timers who partied the first 20 miles meet the math. If you paced the morning right, you roll in around 1:45 p.m. with room to spare.

Silverpine Meadow to The Saddle — Mile 38.2 to 46.0

Grind mostly behind you, you climb again toward The Saddle as the light starts to think about going. This leg is a race against the sun. The Saddle at mile 46 is the most important logistical station of your day: full aid, crew, your last drop bag, and the place you become a night runner.

Your Saddle drop bag is the "night" bag, and packing it right is the difference between a smooth second half and a cold, blind death march. Inside: your primary headlamp, a spare, a warm layer for the temperature drop at elevation, gloves, a beanie, and more calories than you think you need for the dark. Insiders run two lights after dark — a bright one on your head and a second, lower light to throw shadows and show trail texture, because a single flat beam washes the ground out and hides rocks. A dependable 600-lumen headlamp with a real rechargeable cell is the standard night-section lamp for a reason: it has to last you the final 16 miles.

Take the time here to get the night transition right — this is one of the few stops worth five deliberate minutes. Lights on and tested, layers on before you are cold, stomach topped up. If you have a pacer, this is often where they join you. You should leave The Saddle around 4:15 p.m., headlamp ready even if the sun is still up.

The Saddle to Lostman's — Mile 46.0 to 54.3

Dark falls on this leg. The temperature drops, the course narrows to singletrack, and the race turns inward. This is the longest crewless stretch of the night — 8.3 miles to Lostman's, a water-only station with no crew and no drop bag, staffed by volunteers who have been out since dawn.

Your job here is simple and hard: keep eating and keep moving. Nausea, sleepiness, and the low-grade despair of hour fourteen all show up now. None of it is an emergency; all of it is normal. Eat something every 30 minutes even if you do not want to. Watch for the paired reflective eyes at the edge of your headlamp beam — that is wildlife, it is fine, keep going. Lostman's is a top-off-and-go: water, a little food from the volunteers, a thank-you, and back into the dark. You should reach it around 6:30 p.m., and the cutoff is not the threat here — your own morale is.

Lostman's to Ridge End — Mile 54.3 to 58.9

The math changes in your favor now. Under nine miles to the finish across two short legs, and for the first time all day the numbers feel small. Ridge End at mile 58.9 is your last full aid station — the final chance to fuel, warm up, and reset before the run-in.

Do not get sentimental and slow. This is where tired runners drift, chatting at the last big table because the pressure feels off. It is not off; you still have to cover the ground. Take a cup of broth for the warmth and the salt, top your flask, and go. You should leave Ridge End around 8:15 p.m. with the finish genuinely close.

Ridge End to Finish — Mile 58.9 to 62.1

Three miles left, in the dark, on tired legs. It will feel longer than three miles — everything does at hour sixteen — but you are going to finish a 100K. Run what you can, hike what you must, and let it land. When the finish lights appear and the timing mat beeps under your feet, that is 62.1 miles and 11,400 feet done. You should cross somewhere around 7:30 p.m., well under the 10:00 p.m. cutoff, having spent the whole day managing instead of racing.

The Drop-Bag Cheat Sheet

Three bags, three jobs. Pack them the night before, label each with your number and its mile, and resist the urge to improvise a fourth:

• Bracken Hollow (14.2) — the settle-in bag: backup gels for the long crewless push ahead, a spare pair of dry socks, and a small tube of anti-chafe salve to reapply while the problem is still theoretical.
• Coldwater Crossing (30.4) — the reset bag: a dry shirt if you are salt-crusted, a fresh block of calories, and a backup light in case the day drifts past your plan and you touch the dark earlier than you meant to.
• The Saddle (46.0) — the night bag: primary headlamp, spare lamp, a warm layer, gloves, a beanie, and more food than the leg looks like it needs. This is the single most important bag of the day; it decides whether your night is a smooth cruise or a cold, blind grind.

Everything else you carry from the start or leave at home. A drop bag solves one leg — it is not a suitcase, and a bloated bag just slows the stop it was supposed to speed up.

What Actually Got You There

Notice what did not appear in this race report: heroics. No mile you crushed, no rival you outkicked. A first 100K is won in the un-dramatic stuff — the early restraint, the calories you took when you did not want them, the ninety-second aid stations, the drop bags packed to solve one problem each, the out-by times you respected. That is the sport.

If you are crewing for someone else's first 100K instead of running your own, the same day looks different from the chair — here is how to crew it without getting fired. And when you are assembling the vest, the lights, and the poles that make a day like this survivable, start with our gear picks.
