How to build a support crew for a hundred-mile race

There's a moment somewhere around the eighty-kilometre mark of any hundred-mile race when loneliness arrives like weather. The spectators thin out, the aid-station volunteers are tired too, and the trail starts talking back. A good crew does not just hand you a water bottle at that point. They carry the rhythm of the day with you, hold the plan when your brain gives up, and quietly absorb the wobble when your legs stop negotiating with gravity. Building that crew is less about recruiting willing friends and more about assembling a small team that understands the job.

What follows is what I have learned running UTA, the Six Foot, and smaller hundred-milers around the Blue Mountains and out near Bright. Some of it sounds obvious. Most of it was learned the hard way, sometimes at three in the morning, sometimes in a car park at Katoomba when nothing was going right.

Why crew matters at a hundred miles

Aid stations are wonderful. They are staffed by people who have trained for this too, who know the protocol, and who will hand you a cup of broth when you need it most. But aid stations serve hundreds of runners. They are not yours. A crew is yours. They know your run-walk pattern, they know which gel you actually like, and they know that when you stop talking you are not upset, you are just somewhere else.

A crew turns logistics into rhythm. Without them you are digging through drop bags, fumbling with bottles, refilling soft flasks one-handed. With them the bottle appears, the shoes get changed before blisters scream, and the next five kilometres unspool in your head while someone else works out the timing.

In Australia this matters even more. Many hundred-milers here, from the Bob Graham to the Coastal Ultra out west, have long stretches without crew access. Crew vehicles are sometimes limited to a few road crossings, and a missed meeting can mean an extra hour of carrying weight you did not plan for.

Picking the right people

The temptation is to recruit anyone who owns a car. Resist it. A crew member is not a driver. They are a pacer when needed, a navigator, a nutrition technician, a therapist, a cheerleader, and sometimes the person who has to talk you out of quitting at mile seventy.

Pick people who know you, but not too well. Your partner will worry too visibly. Your training partner will push too hard. The friend who has never watched you run a long training block but who shows up reliably and pays attention to detail is gold. In Australia, where many races start in the small hours to dodge afternoon heat, you also want at least one crew member willing to sleep in a car at a trailhead without complaining.

You want one calm person who reads maps and watches the clock, and one louder person who keeps the energy up at sunset. You want someone who can drive long stretches without dozing, because Coonabarabran to Mudgee after sixteen hours is a serious undertaking.

Roles and responsibilities

The cleanest crews run like a small pit crew. One person drives, one person handles nutrition, one person manages gear, and one person owns the runner. That last role is the most important and the hardest to define. The runner-owner watches your stride, notices when your breathing changes, and decides when you eat before you know you need to.

Put names on tasks. Hand the cooler to one person. Give the spare shoes and socks to another. Tell one specific person that they are responsible for telling you when to change socks, even when you do not want to hear it. When everyone owns everything, nothing gets done, and someone ends up holding the wrong bottle at the wrong time.

Write it on paper. A laminated A4 sheet listing aid-station number, distance to next aid, expected arrival window, and what you need there saves hours of confused conversation in the dark.

Communication, pacing, and meeting points

Hundred-mile courses in Australia are not always kind to crew vehicles. The Six Foot out of Katoomba, stretches of the Bibbulmun from Dwellingup, and the Larapinta near Alice Springs do not always have reception. Pick your meeting points before the race and agree on a fallback if someone is late.

Establish a simple protocol. If the runner is more than thirty minutes behind schedule, the crew moves to the next aid station and waits. If the runner is on schedule, they meet at the predetermined place. Do not have the crew drive around looking. The mental load on a tired pacer is already enormous. The runner should never have to wonder where their crew is.

Pacing starts late, often after eighty or ninety miles. The pacer's job is not to run the runner's race. It is to keep them company, slow them on climbs, and prevent hero sections that always end badly. Brief pacers on the runner's tendencies. Tell them when you lie, when you stop talking, when you want silence.

Nutrition and hydration handoffs

This is where a crew earns their keep. A runner at ninety kilometres who has been fuelling with the same gels for twelve hours is a different organism than the runner who started. Flavours change, textures become unbearable, and the stomach starts rejecting anything sweet. The crew needs a plan, not a list of options.

Tailor the menu to the climate. A summer UTA start can swing from cold pre-dawn at Blackheath to sweltering midday on the ridges. Cooler fluids go fast, electrolytes spike, and plain water can be more useful than another sports drink. Reading through hydration strategies for hot weather ultramarathons a few weeks out helps match the menu to conditions.

Practice the handoff. At a hundred-mile race there is no time to fumble with bottles. Soft flask changes, bottle swaps, and gel pickups should each take less than ten seconds. Crew should know the order in which you take calories and the timing between each one. Run a couple of long training blocks where the crew actually meets you mid-run to rehearse.

Contingency planning and crew fatigue

Crew fatigue is real and almost no one talks about it. The runner gets to stop moving eventually. The crew is on their feet for sixteen, twenty, sometimes thirty hours. Build in a working meal plan, a working sleep plan if the format permits, and a working rota so no one is driving more than four hours at a stretch without a break.

Plan for the worst. What happens if the runner DNFs at the next aid station? What if a crew member gets sick? What if the weather turns? Australian summer storms in the ranges can flip a trail into a creek within minutes. Crew vehicles should carry dry gear, torches, charged phones, and printed course notes.

Decide in advance when the crew stops advising. The crew's job ends when the runner is across the line. Until then, the runner decides; the crew recommends.

Rehearsals, briefings, and race-week prep

A briefing document beats a chat. Pull together a one-page crew brief listing the runner's goals, the aid stations the crew will attend, the kit in the vehicle, the contact protocol, and the runner's known foibles. Print three copies, one per crew member.

Drive the course in the dark if you can. Most Australian hundred-milers have at least one section that is runnable in daylight and treacherous after dark. Knowing where the puddles sit, where the trail gets sandy, and where the road crossings are makes a real difference at two in the morning.

Stock the car like a small aid station: salt, electrolytes, real food, plain water, caffeine options, blister kit, spare shoes and socks, a headlamp with spare batteries, a printed map, a power bank, and a change of clothes. Shared spreadsheets and a few crew coordination tools help in the lead-up, but a printed page in a plastic sleeve still wins in a car park without reception.

The day before the race, walk the crew through the brief once. Not at pace, not under stress. Then send them to sleep. You will not sleep, but they will be sharp when it counts. The race is one long logistical exercise wearing a thin layer of running. The crew is the operating system behind it. Treat them like a system you are building, and the hundred miles will give back what you put in.
