This Trail Note sits alongside your Her Trails program. It draws on ultramarathon performance research, sports nutrition evidence, and fatigue and cognition science to help you move through aid stations with less time loss, more calm, and better decisions.
The Art of the Aid Station
How Efficient Runners Move Through Checkpoints
A long trail race is not only a running problem. It is a logistics problem. Fitness matters, but so does your ability to keep momentum when you reach the tables, chairs, bright lights, friendly volunteers, and the temptation to just sit for a second.
In mountain ultramarathon research, total time stopped was strongly linked to overall performance. Faster runners stopped less. That means aid stations are not minor details. They are part of your race outcome.
Aid stations are where minutes quietly compound. The goal is not to rush so hard you miss fuel or safety. The goal is to remove friction so you can keep moving with steady confidence.
The simple equation that changes everything
The time math
Your race time is your forward motion plus everything that interrupts it. Aid stations matter because race time keeps running even when you are standing still.
Why aid stations get harder later in the race
Aid stations become more sticky as fatigue builds. This is not just motivation. It is physiology and cognition.
In long ultramarathons that include major sleep restriction, cognitive performance drops. That matters because aid stations demand decision-making: what to eat, what to carry, what to change, how to adjust your plan, and whether something is a minor discomfort or a developing problem.
When cognition is taxed, simple routines protect you.
The four-part aid station system
Efficient athletes do not wing it in the aid station. They follow a small system that reduces decisions.
A simple four-part flow
Approach: Decide your first action before you arrive. Drink a few sips on the final minute in, and mentally rehearse the order of tasks.
Execute: Do only what is required for the next segment. Refill fluids, take calories, adjust layers, fix one problem if needed.
Exit: Leave while you are still warm. If you need to eat, begin walking out while chewing.
Reset: Once you are back on trail, do a 20 to 40 second check-in: breath, posture, fueling timer, mood.
Refuelling decisions that support speed and stability
Aid station efficiency only matters if you leave fuelled. Under-fuelling creates bigger problems later.
Sports nutrition evidence supports carbohydrate intakes of about 30 to 60 grams per hour for prolonged exercise, and often more for ultra-endurance events when the gut is trained. In ultramarathon field studies, higher carbohydrate and energy intake has been associated with faster segment speed and better overall performance.
Aid station rule for fuelling: Leave each checkpoint with a plan for the first 20 minutes.
If you often forget to eat, set a timer the moment you leave the tables. That one action prevents the most common late-race crash.
Hydration is more nuanced. Overdrinking can be just as problematic as underdrinking. A practical approach is to drink steadily according to conditions, thirst, and your own sweat patterns rather than forcing large volumes.
The cognitive reset that keeps you moving
Because cognition can degrade late in long events, a micro reset helps you make fewer mistakes.
The 20-second reset
Body: shoulders down, jaw soft, breathe low.
Fuel: what is my next bite and when.
Feet: hot spots, grit in socks, lace tension.
Mind: one simple task for the next 10 minutes.
Field card
Approach. Execute. Exit. Reset.
If you can do those four things under fatigue, you can protect hours of performance from being lost in minutes.
Aid stations are not pauses from the race. They are part of the race. When you move through them with calm structure, you protect your rhythm, your energy, and your confidence.
