Ultra runners, do you suffer from nausea?

Do you get nausea and vomiting frequently during races? Have you ever had to drop out of a race due to nausea and vomiting? Have nausea or vomiting affected your race performance? The TWOFUN study (Treatment With Ondansetron For Ultra-marathon associated Nausea and vomiting) is being done to help runners find solutions.

This study will be conducted at the 2019 Tahoe Rim Trail races to look at the effectiveness of a commonly used medication called ondansetron (brand name Zofran) to treat nausea and/or vomiting in runners during a race. Study runners will randomly be given either the medication or a placebo prior to the race to carry with them or store in drop bags in case symptoms arise. If runners continue to have symptoms and have gotten the placebo medication, we will have the ability to give the medication at one of the medical aid stations. We will also ask runners to fill out a quick survey (less than 20 questions) at the race finish or by internet immediately after the race. We are looking to enroll as many participants as possible. There is no cost to you to participate in this study.
