2.2. Study Design
In a randomized, counterbalanced, crossover study design, participants completed two trials: (1) 10 k run with readily available fluid (AL) and (2) 10 k run with pre-placed fluid (PER) (In one trial, participants were given a fluid bottle filled with water to carry with them throughout the duration of the run (AL). To ensure participants always had availability of fluid, additional fluid bottles were placed throughout the course for the participants to use if their initial bottle had become low on fluid. In the other trial, participants were able to consume fluid at fluid stations placed every 3.2 km throughout the course (PER). Participants were given the option to grab a fluid bottle filled with water at the stations and consume fluid for a maximum of 200 m from the fluid station while running.
