Event Detail
Sarawak Energy Isthmus Run was held on Sunday 10 August 2025 at Kuching Isthmus. The organiser reported nearly 6,000 runners from Malaysia and 14 other countries, raising RM360,000 for 12 charitable organisations. This tenth edition introduced a 42.195K full marathon alongside the 21K, 10K and 5K events, with internationally measured longer courses. Start times varied by race, so the stored midnight date is not a flag-off time.
