OSIM Sundown Marathon 2023
During running, I got stomachache , could not even have deep breath, only can walk after 25km. Maybe because this is the first time I tried energy gels. Although got vomiting a bit, felt a bit better, still felt pain. Or maybe because ran too fast in first 21km (1:56), wanted to check my half marathon speed. Or maybe because inhaled water a few times, caused severe coughing. Still unclear.
