New RRWPWater planning is an important logistical and risk management concern of road races. Until now event organizers have used guesswork and experience to estimate water needs on the race course. The Road Race Water Planner© (RRWP) app is the first to provide a strong scientific basis for easily and accurately estimating water needs, thus providing rational and actionable information to simplify logistics and improve risk management. The app can also reduce the environmental and economic impact of water planning while optimizing runner health and performance.

The RRWP uses a patent pending H2Q Technology™ for accurately estimating individual exercise sweat losses and applies it to solve for the large individual variations in sweating that create uncertainty for group water planning. Group estimates are ultimately obtained from a weighted composite RRWP population of more than 9 million marathon runner finishing times. Large sample estimates from individual races reflect the theoretical RRWP population prediction distribution with fidelity in accordance with central limit theory.

Millions of runners compete in thousands of road races annually. Runners are encouraged by major sports medicine organizations to know their sweating rates and to tailor drinking behaviors accordingly to avoid the potential dangers of over- and under-drinking. Unlike H2Q Technology™, RRWP is not intended for use in estimating individual runner fluid needs, nor will it prevent runners from choosing to drink above or below their actual needs. Runners must ultimately take responsibility for their drinking behaviors, but it is the responsibility of event organizers to provide the right amount of water. Therefore, planners should incorporate RRWP rationally into their global water planning decision making process. RRWP is a complement to the experience of event organizers and will greatly help narrow the uncertainties of water planning related to changes in weather, participant numbers, and race distance. And because it provides an accurate estimate of average runner sweat losses, it minimizes the potential for irresponsible drinking behaviors.

Accurate water estimates also reduce waste and costs.  RRWP is consistent with growing sustainability initiatives aimed at incorporating environmentally and socially responsible practices into the operational planning, preparation and execution of road races.

Disclaimer

The Road Race Water Planner© (RRWP) app is intended to assist road race planners in responsibly estimating total fluid and drinking cup needs for runners.  The app uses a patent-pending algorithm for accurately estimating exercise sweat losses in conjunction with a weighted-composite mean of finishing times distributed among more than 9 million runners.  It is not intended for use in estimating individual runner fluid needs, nor will it prevent runners from choosing to drink above or below their actual needs.  Therefore, road race planners should use the app as a valid and responsible starting point from which modifications may become necessary based on independent experience and judgment.  RRWP is a complementary component to the water planning decision making process.  The Road Race Water Planner© app is not a medical app.
