Ultra Park Run Thailand 100 #7 - 24H Bangkok International Championships 2026

REGISTRATION CLOSED (checked 26 October 2026): Organiser-linked booking reports that late entries closed on 23 October 2026 for all categories. This is a registration closure, not a cancelled race. The exact clock time of closure is unconfirmed, so no artificial registration-closing timestamp is entered.

Ultra Park Run Thailand 100 #7: 24H Bangkok International Championships 2026 brings Bangkok's park-running and ultra-distance communities together at Vachirabenjatas Park (Rot Fai Park), Chatuchak, on Saturday 31 October and Sunday 1 November 2026. Organised by Ultra Park Run Thailand with the Miracle of Life Foundation and reported support from the Athletics Association of Thailand, the race festival combines entry-level park runs and endurance racing.

Six competition formats

The official programme advertises 5K, 10K, 50K solo, 100K solo, a 100K five-person team relay and a timed 24-hour ultramarathon. Courses use multiple laps in the city's green parkland, mainly on flat paved paths. This looped format allows repeated visits to hydration and nutrition stations; it is not a point-to-point city marathon. Relay runners should verify team changeover arrangements with the organiser.

The 10K is reported to start at 06:00 on Saturday 31 October and the 24-hour race starts at 10:00 that morning, continuing until approximately 10:00 Sunday 1 November. Other distance-specific flag-off times, wave allocation and cut-off requirements have not been independently confirmed. All clock times here are Thailand local time (ICT, UTC+7); the event's stored overall start refers to the earliest verified race gun, not a common start for all six categories.

Late-entry fees and inclusions

The organiser-linked registration report lists late fees of THB 699 for 5K, THB 799 for 10K, THB 1,900 for 50K, THB 3,500 for solo 100K and THB 3,500 for the 24-hour ultra. The five-person 100K relay was shown at THB 1,180 per runner (THB 5,900 for a complete team). Prices exclude system fees and optional services. An optional personalised finisher-shirt service costs THB 100 where available. Earlier advertised rates for some distances were lower, so these are reference late-entry prices, not a representation that closed registration is still available. The event guide advertises chip timing, event shirts, selected finisher shirts, medals, electronic certificates, water and nutrition stations, medical assistance, baggage storage and toilets; entitlements can vary with category and completion.

Bib collection and race-day planning

The published participant FAQ gives Saturday 31 October collection slots at Rot Fai Park:

• 5K and 10K: 05:00–05:30 ICT.
• 24-hour runners: 08:00–09:00 ICT.
• 50K and 100K: 18:00–20:00 ICT.

These are different category-specific windows; do not assume an ultra bib can be collected at the 5K desk. ThaiRun allows collection by a representative carrying a copy of the entrant’s matching identity document. Posted race kits were advertised at THB 60 per person. Fees are non-refundable, entries non-transferable and deferrals to next year unavailable. Confirm the latest guide directly before travelling, particularly if running the 100K team relay. The map marker is an approximate park-centre locator, not a certified course gantry.
