The Course: A City Loop and a Campus Finish, Run in the Dark
All three Sunday races start and finish on Kanlapaphruek Road, in front of the Golden Jubilee Convention Hall at Khon Kaen University [1]. The marathon heads south-west through the city to a U-turn just before 9 km, then comes back north-east past Wat Nong Wang at about 13 km and the Khon Kaen National Museum at 18 km, where it passes the start-area service point [2]. It then runs north-east out of the centre to 26 km, turns back at a second U-turn at 33 km, and finishes through the university: past the Moh Din Daeng shrine and the KKU Demonstration School at 36 to 37 km, the university stadium at 38 to 39 km and the Agricultural Technology Park at 40 km [2].
The half marathon is mostly a long out-and-back on one straight road north to a U-turn at 11 km, followed by a loop past the university stadium at 16 to 17 km [2]. The 11.55 km mini marathon is a single loop that goes through the city streets and then round the outside of the campus [2][3]. The route maps carry no elevation profile. The visiting runner who ran the mini marathon climbed some gradual hills on closed roads, with police controlling the intersections [3].
The course is AIMS-certified [4], and the race is a full AIMS member [5]. At the 2025 launch Khon Kaen's deputy governor said the route is known for helping runners set personal bests [6].
The Weather: Cool, Dry Air Before Dawn
Khon Kaen airport, about 3.5 km west of the start, recorded 16°C at 3am when the marathon started, with a dew point of 11°C, 72% humidity and a 4-knot wind [7]. It got colder through the night: 15°C at 4am, when the half started, and 14°C from 5am to 7am. It then warmed to 16°C at 8am, 19°C at 9am and 21°C at 10am, when the marathon closed, with humidity down to 49% [7]. For Saturday's fun runs it was 12°C from 5am to 7am [8]. Khon Kaen's governor put race morning at 14°C and said the cool weather helped runners set personal bests [4].
A dew point of 10 to 11°C is dry air for a Southeast Asian race. Sweat evaporates easily in air that dry, and at 14°C to 16°C heat was not a factor before sunrise in 2026. The visiting runner described a cool air mass over the country that weekend [3], so do not count on the same numbers every January. Bring a layer you can throw away for the start. On Saturday there was no bag drop for warm clothing, and runners left their top layers at the start area [3].
Aid Stations and Cut-offs
The 2026 marathon map shows 20 water points, at 4, 6, 8, 11, 13, 15, 17, 18, 19, 21, 23, 25, 27, 29, 31, 32, 34, 36, 38 and 40 km, most with a medical volunteer station [2]. Electrolyte drinks, fruit and sweets were at 11, 18, 21, 29 and 38 km, and toilets at 6, 10, 11, 18, 27 and 29 km [2]. The half has water at 3, 5, 7, 10, 12, 14, 16 and 18 km, with electrolyte and fruit at 10 and 16 km [2]. The visiting runner put it as water every 2 to 3 km, with sports drinks and fruit every 8 to 10 km [3].
The limits are seven hours for the marathon (10am), three and a half hours for the half (7.30am) and two hours for the mini marathon (6.45am) [1]. The marathon map adds checkpoints at 8 km (4.20am), 14.8 km (5.30am), 17.8 km (6am), 25 km (7.10am), 32 km (8.20am) and 37 km (9.10am); the half has them at 5 km (4.50am) and 9.5 km (5.35am) [2]. All of them work out at about 10 minutes per kilometre from the gun. Runners may start up to 15 minutes after their gun; after that the organiser can refuse to let them start [1].
Medals go to finishers inside the limit, and a finisher shirt goes only to marathon and half-marathon runners inside seven hours and three and a half hours [1]. The results still list runners who finished later: the slowest marathon chip time is 7:09:17 and the slowest half marathon 3:56:43 [9].
The Start: Corrals, Crowds and Closed Roads
Runners are put in start corrals by the finish times they entered, and the rules say starting from the wrong corral means disqualification [1]. On race morning there were corrals, an organised bag drop, fireworks for the half-marathon start and long queues for the toilets [3]. The mini marathon started with another 3,200 runners, and the visiting runner spent much of the first 2 to 3 km dodging runners who had started too close to the line and people who were already walking [3].
The roads were closed, with police at the intersections and student cheer groups round the campus [3]. About 2 km from the finish, the half and full marathon runners joined the mini-marathon route and the road filled up again [3].
How Fast the Field Is
Ethiopia's Moges Abate Tefera led the marathon from the start and won in 2:18:11, ahead of Kenya's Barnabas Kiplimo (2:21:22) and Ethiopia's Wendwesen Damte (2:21:33) [4]. Kiplimo had won the 2025 race in 2:18:55 [10]. Marta Tinsae Birehan of Ethiopia won the women's race in 2:45:51, from Kenya's Nancy Githiga (2:47:40) and Ethiopia's Hajer Kahsay Berhe (2:52:34) [4]. The fastest Thais were Nattawat Innum in 2:33:51 and Arunya Hinsui in 2:59:02 [4].
Behind the leaders the field thins out quickly. Tenth place in the marathon was 2:44:46 for men and 3:19:39 for women, on chip time [9]. The median marathon finisher took 4:27, and 451 of the 1,229 finishers broke four hours [9]. In the half marathon, Kindu Sewmehon Tiruneh of Ethiopia won in 1:07:37, and Lodkeo Inthakoumman of Laos defended the women's title in 1:21:43 [4]; tenth place was 1:18:18 for men and 1:30:14 for women [9].
The field is mostly Thai: 899 of the 997 male marathon finishers were Thai [9]. The organiser reported runners from 56 countries [4], against 47 in 2025 [10]. Prize money is 50,000, 30,000 and 20,000 baht for the top three men and women in the marathon, with a separate Thai-only prize of 17,000 baht for first [1]. Age-group winners in the marathon get 5,000 baht, the top five in every age group get a trophy, and the first 100 men and 100 women on gun time get a Top 100 award [1]. On chip time the 100th marathon finisher took 3:12:49 among men and 4:32:14 among women [9]. A woman who can run about 3:20 has a real chance of the overall top ten.
Race Weekend Logistics
Race kits were handed out at the expo in the Golden Jubilee Convention Hall on Friday and Saturday, 9 and 10 January, from 10am to 7pm. A limited number of entries were sold there at the expo price, and a friend can collect your kit if they bring your ID card, a copy or a photo of it [11]. There is no race-day collection [1]. The visiting runner found kit pickup well organised, with English-speaking helpers and coloured tape on the floor leading to the right table, and an expo of 50 to 60 running vendors [3].
The organiser ran free shuttles [12]. On the Friday they ran from Khon Kaen airport to the venue at 9.30am, 1.30pm, 4.30pm and 6pm. On the Saturday they also picked up from the airport, the No. 3 bus terminal and the railway station from 9.30am [12]. On race day three shuttle lines served the hotels. On the Blue line, marathon buses left at 1.30, 1.45 and 2am from stops including the Avani, Green Hotel and Mantra Varee, and return buses ran from 6am to 9am from the Faculty of Pharmacy shop on Maliwan Road, near the start [12]. For Saturday's race there was no shuttle; the visiting runner took a Grab [3].
If you would rather sleep at the venue, the organiser offered two free tent areas: around the convention hall, with mobile toilets and 15 shower rooms, and at the art and culture hall stage [13]. After the race each finisher got a strip of six tickets for food and drink at the finish-area food tents [3]. The organiser's pre-race release promised more than 200 food vendors [6].
In 2026 the marathon cost 1,000 baht early, 1,100 baht normally and 1,300 baht at the expo, with the half at 800 to 1,100 baht and the mini at 600 to 900 baht. Runners aged 60 and over paid half price [1]. Fees are not refunded unless the organiser is at fault, including if the race is postponed by force majeure [1]. Changing the runner on an entry costs 200 baht, and moving up a distance costs 50 baht plus the difference in fee [1].
The Saturday Races
Saturday is for the Elite Fun Run and Fun Run, both advertised at 5.4 km, and the 2.8 km Kids Run, all on the university campus [14][15]. The organiser said more than 5,000 people took part in the Saturday walk-run, held on National Children's Day with activities for families and more than 200 food and drink stalls [14]. The bib and medal said 5.4 km, but the timed race was changed at the last minute to 4.8 km, the distance used in the results [9][3]. It is point-to-point on closed, tree-lined campus roads [3].
Should You Enter the 2027 Race?
Yes, if you want a marathon in Thailand without the usual heat, a seven-hour limit and checkpoints set at about 10 minutes per kilometre, or a weekend with two races: a Saturday fun run and a Sunday race. Club runners have a real chance of an age-group trophy or a Top 100 award.
Think twice if you want a quiet start or wide-open roads early in the race, or if a 1.30am bus is more than you can face. If you run the half or mini marathon for time, start in your own corral and expect walkers in the first few kilometres.
The 22nd edition is on 9 and 10 January 2027 [5]. The organiser has published the same start times (3am, 4am and 4.45am) and the same marathon fee of 1,000 baht early and 1,100 baht normally [16]. The route page still shows the 2026 maps [2], so check for a new course map and the shuttle timetable before race week.
Nobody from this site ran the race. This review draws on the organiser's race information, route maps and reports, the full results, airport weather records, AIMS and one visiting runner's own account.
