Running Remains Safe During Fasting: Expert

RRI.CO.ID, Bogor - Running during Ramadan fasting remains safe for healthy individuals when timing intensity and hydration are properly managed. Agil Wahyu Wicaksono from IPB University Faculty of Medicine and Nutrition made the statement.

“Medically running during fasting is not prohibited and healthy individuals may perform light to moderate exercise,” said Agil on IPB University website on Wednesday, 18 February 2026. He noted proper timing intensity and hydration remain essential for maintaining safety during Ramadan exercise routines.

He affirmed understanding body condition helps maintain exercise benefits without causing health risks during fasting periods. Studies show healthy individuals may perform light to moderate exercise during Ramadan without significant medical complications.

However runners should consider timing intensity and physical readiness before starting running sessions while fasting. Exercise during fasting should prioritize fitness maintenance rather than pursuing maximum performance or competitive targets.

The safest running time is after breaking the fast when fluids and nutrients are replenished. At this stage dehydration risk becomes lower because the body has received food and drink intake.

Running shortly before breaking the fast is also considered relatively safe for short light sessions. Duration around fifteen to thirty minutes allows fluids to be replaced immediately after finishing exercise.

Morning run after suhoor remains possible although dehydration risk is higher than other recommended periods. Therefore intensity should stay light to moderate with controlled breathing and comfortable physical responses throughout exercise.

Exercise must stop immediately if weakness, dizziness, nausea, trembling or excessive thirst appear during running sessions. These signs may indicate dehydration or decreased blood sugar levels requiring prompt rest and recovery actions.

Hydration strategy becomes essential during Ramadan to maintain performance and prevent fluid imbalance risks effectively. Research in Indonesia recommends a four two two drinking pattern between iftar night and sahoor periods.
