An aid station is a designated checkpoint along a trail or ultra race that provides water, electrolyte drinks, food, and often medical support, drop-bag access, and a place for crews and pacers to meet runners. Aid stations let runners refuel and resupply, and managing them efficiently — getting in and out quickly — is a key race skill, especially in ultras.

Frequently asked questions
What is an aid station?
An aid station is a support point set up along a trail race course, typically every few miles, stocked with water, electrolyte drinks, and food (from snacks to hot food in ultras). Many also offer medical help, access to your drop bag, and a spot where your crew and pacer can meet you. They keep runners fueled and hydrated through the race.
What do you do at an aid station?
Refill your water bottles or hydration vest, grab calories and electrolytes, take care of any issues (blisters, chafing, gear), and meet your crew or pick up a pacer if allowed. In ultras, having a clear plan to refuel and handle needs quickly keeps aid-station stops short, which can save significant time over a long race.
How long should you spend at aid stations?
As little as needed — aid-station time adds up, and lingering can sap momentum and motivation. Experienced ultrarunners plan exactly what they need at each stop, often having crew or drop bags ready, to get in and out efficiently. For early or less critical stations, quick grab-and-go is ideal; later stations may justify longer stops.
