Abstract

A 55 year old runner covered 160 km within a 20 hour period. His speed averaged 18.16 km/h, at an estimated 59.1 of maximum oxygen intake. After the first four hours of running, one of five fluids was taken in rotation every twelve minutes. Volumes ingested were greatest for water (740 ml/h) and least for an ice-cream/syrup mixture (320 ml/h.) The heart rate for the final four hours (125/min) was not increased relative to oxygen consumption for this portion of the run. Constancy of heart rate, continued urine production and formal fluid balance calculations all indicate that hydration was well maintainedover the run. Caloric intake averaged 480kcal/h(2.01 MJ/h), being greatest forthe ice-cream/syrup mixture; the energy deficit (56 kcal/h, 235 kJ/h) was small during that part of the run in which food was provided.
