This Week In Running: November 10, 2025

World records, World Trail Majors, and win streaks. If that’s not enough, there were two USA Track and Field (USATF) championships and the Skymasters event too.

You can also check out our race coverage from the weekend:

• Anne Flower Sets 50-Mile World Record at the 2025 Tunnel Hill 50 Mile
• Caitriona Jennings Sets 100-Mile World Record at the 2025 Tunnel Hill 100 Mile

Tunnel Hill – Vienna, Illinois

World and course records are being canceled quicker than flight schedules. Old times disappear faster than security at the Louvre. That’s how it is in 2025, and so expectations were high at Tunnel Hill.

World records were set here in 2021, 2023, and 2024, and the women did even better than that this year. There was not one, but two new world records, and a longstanding North American women’s record went down too.

50 Mile

The 50-mile race was also the USATF 50-Mile Road Championship. There was a $4,000 prize purse that paid $1,200 to the winners.

Anne Flower broke the women’s world record by 13 minutes. Flower ran 5:18:57. That’s 6:23 per mile, and it’s way up on Courtney Olsen’s year-old former 5:31:56 world record. On top of the first-place cash prize, Flower earned a $5,000 course-record bonus, too. In August, she broke the 31-year-old Leadville Trail 100 Mile course record in her 100-mile debut.

Former world record-holder Olsen was second to the 50-mile mark in 5:33:59, barely two minutes back of her old mark, and then she kept going to win the 100k race in 6:59:55. That sub-7 hour time was a new North American 100k record, almost a minute better than an Ann Trason mark that had stood since 1995. Recovery will need to be quick for Olsen, as she’s got the IAU 50k World Championships in India in one month.

Behind Flower and Olsen, Emily Hugo was third in the women’s 50-mile race in 5:50:54.

There was no new world record in the men’s race, but Brogan Austin won in 5:02:54, and Geoffrey Burns was second in 5:06:28. John Donovan was third in 5:14:14. Brogan is now the ninth-fastest man ever over 50 miles in North America.

100 Mile

Ireland’s Caitriona Jennings ran 12:37:04 to win the women’s race and set a new women’s world record. She won $1,250 in first-place prize money, plus a $7,500 bonus for a new world record, plus $6,000 for a new course record. That’s $14,750. Jenning’s run eclipsed Camille Herron’s old 12:42:39 world record from 2017 set at this same race.

Second and third in the women’s 100-mile race were Piper Gray and Kaydi Bolos in 16:33:50 and 16:53:53.

Less than 13 minutes separated the first three men, and all got close to breaking 12 hours. Perennial Tunnel Hill podium-getter Phil Young escaped from Reese Slobodianuk to win in 12:03:27. Slobodianuk chased to second in 12:05:38, and third-place Rob King ran 12:16:09. Young and Slobodianuk are now the fourth- and fifth-fastest North American men ever over 100 miles, and King is the ninth fastest. Young won $1,250 in first-place prize money.

Marathon

Like Olsen, Allison Mercer is on Team USA for the 50k World Championships team, too. Mercer went shorter for her final tune-up and won the marathon distance in 2:50:05. Joshua Moore was just ahead as the men’s winner in 2:47:03.

Grampians Peaks Trail – Grampians National Park, Australia

The Australian races were part of the World Trail Majors, and although that brought in a few international runners at the top, the fields were mostly from the host country. The races were in a mountainous area in Australia’s southeast corner, three hours west of Melbourne.

GPT 100 Miler

The long course went 162 kilometers with 7,700 meters of climbing covering the entire Grampians Peak Trail on a north-to-south run. That’s 100 miles and 25,262 feet, and race winners won $1,620 each, or $10 per kilometer.

Man Yee Cheung (Hong Kong) was victorious in the women’s race in 27:58. It was her second big win of the year, adding to an earlier Mt. Fuji 100 Mile crown. It was all Australian runners behind her. Nicole Paton and Lou Clifton were second and third in 29:12 and 30:24.

For the men, Caleb Olson (U.S.) came in as a heavy favorite, and he won in 21:19. It was the latest win in a standout year. Olson earlier this year won Transgrancanaria, Western States 100, and a pair of 50k races in his home state of Utah. His lone blemish on the year was an early drop at August’s Trail World Championships Long Trail race. Before Grampians, Olson shared that this was a longer test — 21 hours in this case — with an eye toward next year’s UTMB.

George Knight (Australia) and Steve Miller (Australia) were second and third in 23:16 and 23:41, respectively.

GPT 50k

Fu-Zhao Xiang (China) won her third World Trail Majors Short Series race of the year. Xiang ran 5:05 and she is the series leader with one race to go. Second-place Lucy Bartholomew (Australia) was only 10 minutes back in 5:15, and she did it immediately after winning the nearby Bright 4 Peaks four-day stage race. Maggie Lennox (Australia) was third in 5:40. 

In the men’s race, Peter Fraňo (Slovakia) gave Dan Jones (New Zealand) a rare Southern Hemisphere defeat, and Ricardo Cherta (Spain) was a close third. Fraňo won in 4:29 to Jones’s 4:31. Fraňo’s win capped a big 2025 where he firmly established himself among the world’s best. He earlier won Transvulvania, was ninth at Western States 100, and was most recently fifth at the Trail World Championships Long Trail race.

Although Fraňo and Jones have international reputations, comparatively unknown Cherta was a really close third in 4:32.

Moab Trail Marathon – Moab, Utah

Marathon

Although the half marathon was the event’s top draw this year, but the full marathon had Mira Ensley-Field and Colin Cooper as its winners in 4:21 and 3:34, respectively.

Half Marathon

The half marathon was this year’s USATF Half Marathon Trail Championships and paid out $6,600 in prize money, with $700 to the winners. It took a course record to win for both the women and men.

Tayler Tuttle ran away with the women’s win in 1:32. She was nearly five minutes better than everyone else. A former University of Colorado runner, Tuttle quietly had a strong year on the trails with wins at the Tamalpa Headlands 50k and Twisted Fork 15k, among other results. Camila Noe and Alicia Vargo were second and third in 1:37 and 1:38.

Men’s winner Christian Allen hasn’t yet turned to the roads for the winter. He ran 1:18 to beat Andy Wacker by two minutes and to finish ahead of trail rookie Camren Todd by three minutes. Wacker came in at 1:20 and Todd was at the finish in 1:21. Todd could be one to watch in 2026. He recently ran for Utah State University and ran 28:10 in a 10,000-meter track race in April 2025.

Marató Dels Dements – Eslida-Ain, Spain

The race was the Skymasters, the end of this year’s Skyrunner World Series. That meant extra scoring points, enough to possibly shake up the top rankings, and it made this one of the year’s deeper Skyrunner World Series races too.

The race was run on a big 42-kilometer loop course with nine big climbs and descents totaling 3,800 meters of gain.

Women

All year long, Anastasia Rubtsova (Neutral) has dominated the Skyrunner World Series, winning six of the events. Rubtsova led all of it and won the race in 4:55. Naiara Irigoyen (Spain) was second in 5:07, and Patricia Pineda (Spain) was third in 5:09.

Rubtsova also won the series, for the second year in a row, and Irigoyen and Pineda were second and third in the series, too.

The women’s top five was:

1. Anastasia Rubtsova (Neutral) – 4:55:25
2. Naiara Irigoyen (Spain) – 5:07:51
3. Patricia Pineda (Spain) – 5:09:06
4. Marta Martínez (Spain) – 5:13:14
5. Denisa Dragomir (Romania) – 5:16:15

Men

Manuel Merillas (Spain) and Frédéric Tranchand (France) broke from the group early, and after 25k, Merillas seized the lead. Merillas won the late-season race in 4:02. Luca Del Pero (Italy) surged late from fourth to second and was three minutes back in 4:05. Tranchand was another minute back in third at 4:06.

A year after finishing second, Del Pero won the series this year, and Alain Santamaría (Spain) was second, and Merillas was third.

The men’s top five was:

1. Manuel Merillas (Spain) – 4:02:08
2. Luca Del Pero (Italy) – 4:05:12
3. Frédéric Tranchand (France) – 4:06:21
4. José Manuel Quispe (Peru) – 4:13:59
5. Alain Santamaría (Spain) – 4:14:29

Daniela Rota (Italy) and Fredrik Bruseth Toreli (Norway) were tops in the 53-mile Le Maioliche di Laterza contest. The two winners finished in 8:56 and 7:10.

Prades Epic Trail – Costa Daurada, Spain

The 80k, 50k, and 25k races all paid prize money. It was 3,000 Euro to win the 80k, 2,000 Euro  for the 50k, and 1,200 Euro for the 25k.

Gemma Arenas (Spain) and Alejandro Mayor (Spain) won the long course in 10:05 and 8:24, respectively.

The 50k winners were Anna Tarasova (Spain) and Jose Angel Fernandez (Spain) in 6:00 and 4:00, and in the 25k it was Núria Gil (Spain) and Jan Torrella (Spain) in 2:15 and 1:49. Torrella scored the win 19 seconds ahead of Antonio Martínez (Spain).
