The SuperHalfs half-marathon series, comprising the leading half-marathon running events in Lisbon, Prague, Copenhagen, Cardiff and Valencia, will reach out to runners globally and encourage them to take part in the mass races of the inaugural World Athletics Road Running Championships in Riga on 30 September – 1 October 2023.

The organisers of the Championships in Riga (WRRC Riga 23) are certain that the collaboration with the SuperHalfs half-marathon series will help recreational runners across the globe discover the opportunity to be part of the World Championships in Riga. Riga is preparing to welcome thousands of recreational runners from at least 100 countries to the World Athletics Road Running Championships, and the communications support from SuperHalfs will certainly help achieve this goal.

Sašo Belovski, managing director of SuperHalfs, comments: “Riga is fortunate not only to host the inaugural World Athletics Road Running Championships and mass races, but also to offer runners the opportunity to take part in three mass races over the championships weekend – half-marathon, 5km, and road mile. At SuperHalfs, we are all about encouraging runners to participate in beautiful running adventures, and the WRRC Riga 2023 will undoubtedly be an unmissable experience in 2023!”

The collaboration between WRRC Riga 23 and SuperHalfs will involve communications support through all of SuperHalfs and member races’ channels encouraging running at the World Championships in Riga.

Aigars Nords, the head of the Local Organizing Committee WRRC Riga 2023, commented: “The biggest challenge for us as the organizers of the inaugural World Athletics Road Running Championships is to help recreational runners get used to the idea that anybody can participate in a mass race at the world championships. We believe that our collaboration with SuperHalfs will help us get this message across and persuade running enthusiasts to come and test themselves in Riga in 2023!”

Any recreational runner can register for the road mile (1609m), 5km and half-marathon distances of the World Athletics Road Running Championships in Riga on the official website

A special promotional code RIGA23SUPERHALFS015 entitles you to 20% off the cost of entry valid until 28 February.

Race news Košice Peace Marathon

6,000 already registered for Košice in 100th year

Europe’s oldest marathon celebrates centenary

O cisla f listonova

The oldest marathon in Europe is enjoying great interest in its upcoming 100th year.

In the first 50 days from the opening of registration, more than 6,000 runners have already signed up, which is about 50% of the entire planned capacity. There are still more than eight months left before the start, so it will be interesting to see how the numbers continue to develop.

Naturally, domestic runners play first fiddle, while on the other rungs, under the flags of dozens of countries, are mainly runners from Poland, the Czech Republic, France, Hungary, the UK and Germany.

In the meantime, the organisers have confirmed that all the main disciplines of the programme, i.e. the Marathon, Half Marathon and Relay, will take place together on Sunday, 1 October. One day earlier, on Saturday, 30 September, the programme will be dominated by the U.S. Steel Family Run.

New US record and photo finishes make for excitement in Houston

Gebrekiden first woman to run 1:06:28 on American soil

Thrilling sprint finishes for the men, dominant performances by the women and a new American half marathon record highlighted the Aramco Houston Half Marathon and Chevron Houston Marathon.

Hiwot Gebrekiden attacked the course early and alone, going through the five-mile mark well under record pace while Emily Sisson, aiming for an Amercan record stayed 30 seconds back, sharing the opening miles with South Africa’s Dominique Scott. By 10km both women were on their own. Gebrekiden’s pace slowed and the course record fell out of reach, but the gap she had opened up secured her the victory in 1:06:28. Sisson came through the finish chute seconds later as a roaring crowd cheered her to a second place finish in 1:06:52, shattering the record she set just nine months ago.

“I was soaking up the energy,” said Sisson who also holds the American record in the marathon, “I was happy with how I was able to finish today. Whenever I can pick it up in that last half mile, I know I have done it right.” En route to her record-breaking run Sisson tied the American record for 10 miles (50:52) and broke the American record for 20K (1:03:26).

While no records were set in the men’s half marathon, the finish was one of the closest and most exciting in race history. With one mile to go, Leul Gebresilase of Ethiopia and Wesley Kiptoo of Kenya had turned the race into a duel, trading surges going into the final turn. Kiptoo, a standout while at Iowa State, looked to have the advantage. But, just meters before the finish, Gebresilase slipped by to break the tape by less than a second 1:00:34 to 1:00:35.

“Today the competition was very good,” said Gebresilase, who told reporters he was aiming for the course record of 59:22. “I pushed at the end and my hamstring started cramping, but I am happy to be the winner.”

In the women’s marathon, Hitomi Niiya set out to break the Japanese women’s marathon record of 2:19:12, a time that is also the Chevron Houston Marathon course record. With the aid of a pacer, Niiya waited patiently as early leader Muliye Dekebo of Ehtiopia set a blistering early pace well below 2:17 through 15K. Niiya caught Dekebo at the halfway point and the pair ran side-by-side for the next five miles before Dekebo’s ambitious start caught up to her. From there, it was all Niiya and her pacer clicking off 5:20 per mile and inching dangerously close to the record. After the pacer stepped off the course, Niiya struggled and crossed the line in 2:19:24. Despite missing the Japanese record by 12 seconds, it was still a nearly two-minute personal best and the second fastest time in race history.

“Running by myself was a very powerful feeling,” said Niiya who set the Japanese Half Marathon record here in 2020, “but with cheering and support I was able to do it.”

Dekebo held on to second, finishing nearly six minutes back in 2:25:35.

The men’s marathon played out differently. Despite recruiting a pacer to run 2:07, a pack of seven men ran stride for stride through 30K at 2:10 pace. By 35K, it was down to five and just after 40K, it was a two-man race between Dominic Ondoro of Kenya and Tsedat Ayana of Ethiopia. Ayana looked to have the advantage as the marathon turned into a sprint with 400m to go. But, in a repeat of the half marathon just an hour earlier, Ondoro had one last surge, passing a flailing and visibly tired Ayana in the final seconds of the race. The winning time of 2:10:36 was just one second faster than second place and the closest finish since 1996. Teshome Mekonen who became a U.S. citizen in August of last year, was the top American finisher in third place (2:11:05.)

An inaugural Half Marathon record for South Sudan was set in this AIMS-certified event by winner Yach Majok Koon.

It was a day of friendship and happiness as Africans ran from Egypt, Sudan, Ethiopia and South Sudan ran for peace on the fastest half marathon course in all Egypt and in good weather conditions.

Yach Majok Koon won the race with some brave front running after the 15km point. Judges from the Egyptian Athletic Federation were present at the start/finish line to ensure performances could be ratified.

Race news B.A.A. Boston Marathon

Edna Kiplagat declared winner of 2021 Boston Marathon

First runner over the line disqualified

Edna Kiplagat was second across the finish line in the 2021 Boston Marathon but has now been declared the winner of that race after the disqualification of the woman who finished ahead of her.

Diana Kipyogei tested positive for a performance enhancing drug and then contested the positive finding. The end result was that Kipyogei was banned for six years and will not be eligible to compete again until June 2028.

Kiplagat now becomes a two-time winner of the Boston Marathon having previously won the race in 2017. She also becomes the oldest-ever female winner of the race at 42 years and 5 months, surpassing the record of Miki Gorman, from the 1977 race, of 41 years and 8 months.

Houston announces elite field

Sisson to battle Dibaba for first place

The Houston Marathon Committee announced today (3 January) the elite athletes who will chase the USD 10,000 (EUR 9,430) first-place prize in this historically fast race.

American records in the half marathon and marathon were set in Houston last year, but by the end of 2022, Emily Sisson had broken them both. Houston will be Sisson’s first race since running 2:18:29 at the Bank of America Chicago Marathon in October, shattering Keira D’Amato’s record by 43 seconds. Earlier in the year, her 1:07:11 performance in Indianapolis shaved four seconds off Sara Hall’s half marathon record.

“I have really enjoyed racing here in the past and am excited to start my 2023 season in Houston,” said Sisson who finished fifth in the 2019 Aramco Houston Half Marathon. “I felt good coming out of Chicago and am really looking forward to another opportunity to race.”

Sisson will have to contend with one of the greatest distance runners of all time as Tirunesh Dibaba of Ethiopia makes a return to competition after a more than four-year hiatus. The three-time Olympic gold medalist and five-time world champion has not raced since 2018 but says after giving birth to a second child in 2019 and then battling COVID-19, she is ready to add another chapter to her storied career.

“Houston is a famous race and my training has been going well,” said Dibaba, the 2017 Chicago Marathon Champion. “It seemed like the best way to test myself and see what could be next.”

Other top contenders in the women’s half marathon elite field include 2021 Berlin Marathon runner-up Hiwot Gebrekidan of Ethiopia and 2022 World Championship Marathon fourth-place finisher Nazret Weldu of Eritrea. Dom Scott will attempt to break the South African half marathon record of 1:06:44, after a 3rd place finish in Houston last year. The top Americans include 28-time U.S. Champion Molly Huddle who set the then-American record here in 2018, as well as World Champion and Olympic Bronze Medalist Jenny Simpson who will make her half marathon debut.

“All of the racers I am learning from speak so highly of their experience with the Aramco Houston Half Marathon,” said Simpson. “It’s the perfect place for me to make my half marathon debut because the timing, course and organization are so well tested.”

In the men’s race, Edward Cheserek of Kenya is coming off a 1:00:13 half marathon personal best in Valencia last month. “After Valencia this fall, I’ve trained harder and think sub-60 is possible,” said Cheserek, a 17-time NCAA Champion at the University of Oregon. “Houston is known for being a fast course and I want to have a chance at a personal best.”

Cheserek will face off against 2019 champion Shura Kitata of Ethiopia who lines up for his fourth Aramco Houston Half Marathon. With career marathon victories in London, Frankfurt and Rome, Kitata says he “feels home and comfortable in Houston.”

Other contenders to watch are Ethiopia’s Leul Gebresilase Aleme, runner up at last year’s London Marathon, and 2020 Olympian Mohamed El Aaraby of Morocco. The top American in the field is Conner Mantz of Utah. Mantz, the 2020 and 2021 NCAA Cross Country Champion at BYU, made his much-anticipated marathon debut in Chicago last October running 2:08:16, the fastest debut ever by an American-born runner.
