About Our Research Program

Since 2006, the Western States Endurance Run (WSER) has supported basic, applied, clinical and behavioral research associated with the event. The Medical Research program seeks proposals to support research directly applicable, but not limited to, ultramarathon running, running performance, health issues for runners, or using the event as a model for other conditions.

Publication Summary: Citation refers to a Letter to the Editor reporting that there was a significant rise above pre-race levels in blood concentrations of norepinephrine, 3,4-dihydroxyphenylacetic acid (DOPAC; a dopamine metabolite) and ß-endorphin while running the 1980 Western States Endurance Run. The authors indicate that the findings suggest an important interaction between the central nervous system and the periphery as a result of high-level physical exertion.
