International Anti-Corruption Day Run 2026: Run For Dad

International Anti-Corruption Day Run 2026: Run For Dad is a charity walk-run staged by Thailand's Anti-Corruption Foundation as part of activities surrounding International Anti-Corruption Day and Thailand's Father's Day. The event combines competitive road racing with a public-health and fundraising programme, with proceeds supporting anti-corruption campaigns, people affected by anti-corruption work, public-welfare activities and renovation work at Ratchamongkol Hall in Suan Luang Rama IX Park.

The race is based at the Gate 4 Daoruang activity area in Suan Luang Rama IX Park, Bangkok, and the organiser describes the course as linking Suan Luang Rama IX with Nong Bon Lake Park before returning to the event precinct. The competitive programme begins with the half marathon at 05:30. Its 3 hour 30 minute cut-off closes the course at 09:00. The 10K and 5K both start at 06:00; the 10K has a two-hour cut-off. A 3K VIP charity walk starts at 06:10. The organiser caps entries at 500 for the half marathon, 600 for the 10K, 400 for the 5K and 150 for the VIP walk, with the overall registration timeline stating a 2,000-entry ceiling.

The 21K and 10K are timed races with male and female age-group competition. The leading Thai man and woman in each of those distances are eligible for a Royal Trophy from Her Royal Highness Princess Maha Chakri Sirindhorn, with additional age-group trophies. Overall cash prizes are also published for the top three men and women in both timed distances.

The live registration page currently lists registration through 31 October 2026 or until the 2,000-entry quota is reached. Runners may choose paid EMS delivery of their shirt, bib and timing materials. Those collecting in person can pick up their race pack on 4 December from 11:00 to 18:00 at the JOG&JOY counter at Seacon Square, Srinakarin Road. The organiser requires entrants to bring their bib on race morning and states that lost or forgotten bibs will not be replaced.
