Heat-acclimated distance runners (N = 16) performed three trail runs with no water, two hip-mounted water bottles, or a water reservoir. Few physiological variables differed between the two hydration methods. Ss preferred the reservoir method.

Implication. A reservoir storage and delivery system is preferred by athletes although its effects are no different to those of traditional water bottle storage and fluid delivery.
