Event Detail
Run To End Polio Half Marathon 2026 is a community running event scheduled for Sunday 20 December 2026 at Krasiao Dam (เขื่อนกระเสียว) in Dan Chang District, Suphan Buri. The event brings long-distance runners, recreational participants and supporters of the effort to end polio together in the scenic reservoir setting of western-central Thailand.
Running beside Krasiao Dam
Krasiao is a large earthen irrigation dam in Huai Khamin, surrounded by the rural scenery of Suphan Buri. The 2026 race offers four distances: a 21.1 km half marathon, 10 km, 5 km, and a relaxed 3 km option. This makes it suitable for runners interested in a longer timed challenge as well as friends and families wanting to participate over a shorter distance. The organiser has not yet published enough verified detail to claim that every distance follows a particular lakeside route; check the official course maps when released.
Registration options
The 2026 booking partner currently lists standard entry at THB 700 for 21K and THB 500 each for 10K, 5K and 3K. A THB 1,000 VIP entry is also listed for each of the four distances. These are advertised entry prices, subject to the booking system's final availability and conditions. No reliable registration-closing date is published on the current-edition booking page, so a deadline has not been invented.
What participants should know
The organiser's current event listing confirms the date, venue and distances, but individual flag-off times, route maps, cut-off times, exact bib-collection dates, hydration provision, finisher entitlements and award details have not been verified. The calendar's date-only placeholder is not an official midnight start time. Participants should obtain their own race-day timetable and instructions from the organiser before making plans, especially if travelling to Dan Chang from Bangkok or elsewhere.
Runners should also check current registration terms, eligible age groups, refund rules and any medical or identification requirements directly with the organiser. The event name reflects the international public-health aim of ending polio, but the organiser has not specified a verified donation amount or share of individual entry fees, so none is claimed here.
For 2026 entries, see the current event registration and category page. For current instructions and changes, contact the Run To End Polio organiser on Facebook or call +66 92 262 9635.
Registration status checked 25 October 2026
The ThaiJogging organiser-registration portal still lists the 20 December event under active events, with standard and VIP registration choices visible. This is evidence that a booking page is being advertised, not confirmation that payment will succeed or that all distances have places remaining. The 29 March 2026 Mini–Half Marathon shown elsewhere in race calendars is an earlier, separate listing; check that you are booking the 20 December edition.
