Summary

This study looks at how running an ultra-trail race (80 or 160 km) affects the heart's function in adult amateur runners. Researchers will use echocardiography and blood tests before, during, and after the race to see if there are temporary changes in heart function and biomarkers. The goal is to understand how the heart adapts to extreme endurance exercise and whether recovery happens within a week.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to: If successful, this study could reveal how extreme endurance exercise affects the heart, potentially guiding future monitoring strategies for athletes.
What could go wrong: This is an observational study, so it cannot prove cause and effect. Results may not apply to all runners, and the small sample size limits generalizability.
