A wide swath of North America — from the Wasatch Front in Utah to the shores of Lake Superior in Wisconsin, from the mountains of Maine to the streets of Longueuil, Quebec — came alive with marathon racing over the weekend of May 16–18, 2026. Twenty-two events drew a combined total of roughly 9,600 finishers, spanning road and trail, flat and mountainous, mass-market city events and intimate backcountry adventures. The weekend’s flagship performances came out of Denver and Cleveland, where the Colfax and Cleveland marathons each drew fields well north of 2,000 runners. Here is a complete race-by-race breakdown.

Colfax Marathon — Denver, CO | Saturday, May 17

♂ Alec Hornecker 2:27:56  |  ♀ Hali Hafeman 2:55:26  |  Finishers: 2,915  |  Avg: 4:36:39

The Mile High City delivered the weekend’s largest field by a significant margin, with 2,915 runners completing the Colfax Marathon through Denver’s storied neighborhoods, past Colfax Avenue’s neon-lit storefronts and into the city’s parks. Alec Hornecker claimed the men’s title in a sharp 2:27:56 — the fastest winning time of the entire weekend across all events — beating out Ryan Montera (2:35:15) and Patrick Keeley (2:36:31). On the women’s side, Hali Hafeman ran an emphatic 2:55:26 to claim the crown, with Emily Stoodley (2:59:31) and Chelsea Factor (3:03:10) rounding out a competitive podium. Denver’s elevation (roughly 5,280 feet) makes any sub-2:30 winning time a genuine performance of note.

Cleveland Marathon — Cleveland, OH | Friday, May 16

♂ Jacob Kocis 2:21:51  |  ♀ Ashton Swinford 2:44:37  |  Finishers: 2,011  |  Avg: 4:37:10

Over two thousand runners turned out for the Cleveland Marathon on Friday, making it the weekend’s second-largest event. Jacob Kocis produced arguably the most eye-catching individual performance of the entire weekend, crossing the finish line in 2:21:51 — a time that would slot comfortably into the results of many international city marathons. Tyler Polman (2:32:03) and Andre Bollam-Godbott (2:33:24) gave chase but could not close the gap. Ashton Swinford’s 2:44:37 women’s victory was equally commanding, nearly nine minutes clear of runner-up Emily Ambrose (2:53:35), with Sarah Lima (2:55:08) finishing third. Cleveland delivered both speed and volume in equal measure.

Ogden Marathon — Ogden, UT | Friday, May 16

♂ Benjamin Berlin 2:25:35  |  ♀ Paige Nelson 2:38:42  |  Finishers: 1,515  |  Avg: 4:26:31

Utah’s marquee spring marathon made a strong case as the most depth-laden race of the weekend. Benjamin Berlin edged Braden Perry by just 22 seconds — 2:25:35 to 2:25:57 — in one of the weekend’s closest men’s finishes, with Tyler Lyon (2:27:02) a further 65 seconds back. Paige Nelson’s 2:38:42 women’s win stands among the fastest of the entire weekend at any event. The average finishing time of 4:26:31 across 1,515 runners speaks to a field that trends fast, befitting a course that drops nearly 4,000 feet over its descent from the Wasatch Range. Ogden’s top-three women — Nelson, Jennifer Smith (2:52:23), and Leslie Smith (2:54:06) — were all inside 2:55, a remarkable cluster of quality.

Marathon de Longueuil — Longueuil, QC, Canada | Saturday, May 17

♂ Corentin Provost 2:40:38  |  ♀ Charlotte Huebner 2:58:22  |  Finishers: 554  |  Avg: 4:10:49

The largest Canadian marathon of the weekend attracted 554 finishers to the south shore of the St. Lawrence River, just across from Montreal, and the collective speed on display was impressive — a field average of 4:10:49, the sharpest of any race with more than 200 finishers this weekend. Corentin Provost took the men’s race in 2:40:38, leading Gabriel Moreau (2:42:51) and Wilhelm Menet (2:46:09) across the line. Charlotte Huebner was equally authoritative in the women’s race, running 2:58:22 ahead of a strong chasing pack led by Jade Dusablon (3:00:05) and Eliane Cousineau (3:10:55). Longueuil’s flat, urban course continues to produce fast times.

Med-City Marathon — Rochester, MN | Saturday, May 17

♂ Michael Walentiny 2:33:05  |  ♀ Miriam Sader 2:55:04  |  Finishers: 452  |  Avg: 4:18:45

The Mayo Clinic’s hometown showed up in force for the Med-City Marathon, with 452 finishers and a pair of commanding victories. Michael Walentiny’s 2:33:05 held off Jeremy Martin (2:35:20) and Alex Martin (2:41:25) — two runners sharing a surname who may have been keeping the competition in the family. Miriam Sader’s 2:55:04 women’s win was one of the top women’s marks of the entire weekend, a full 12 minutes clear of runner-up Leah Knowles (3:07:35). Rochester’s flat course through the Minnesota river valley has a well-earned reputation for delivering fast conditions.

EPIC Marathon and Running Festival — Green Bay, WI | Saturday, May 17

♂ Adam Rzentkowski 2:20:55  |  ♀ Autumn Canavera 3:05:04  |  Finishers: 397  |  Avg: 4:11:03

Green Bay’s EPIC Marathon delivered one of the weekend’s most striking winning performances: Adam Rzentkowski’s 2:20:55 was the second-fastest men’s winning time of the entire weekend, trailing only Cleveland’s Kocis by less than a minute. Riley Siltman (2:28:19) and Matt Kasten (2:34:48) chased hard but could not answer. Autumn Canavera won the women’s race in 3:05:04, edging Grace Flores (3:09:28) and Becky Vander Heiden (3:10:03) in a tightly contested podium where all three finished within five minutes. The 397-runner field produced a brisk 4:11:03 average — a sign of a consistently fast course along the shores of Lake Michigan.

Capital City Marathon — Olympia, WA | Friday, May 16

Washington’s state capital hosted 306 finishers on a course that winds through the Pacific Northwest’s signature mix of evergreens, water views, and rolling terrain. Roman Kirkov took the men’s win in 2:36:33, just 80 seconds ahead of Kenny Krotzer (2:37:53), with Tyler Flannery (2:44:25) third. The women’s race produced a striking statistical cluster at the top: Dani McDowell (3:27:29), Rachael Blank (3:28:13), and Faith Heisler (3:28:35) finished within just 66 seconds of each other — barely a minute separating the entire women’s podium, a remarkable coincidence of fitness and pacing.

Thomas Cameron crossed in 2:30:03, with Nate Clayson (2:31:06) and Joshua Branham (2:35:20) close behind in a tight men’s podium. Amanda Frketich’s 2:47:58 women’s win deserves special recognition — it ranks among the fastest women’s winning times of the entire weekend and reflects a genuine talent performing at a high level. Brooke Deans (2:53:01) gave chase, with Kathleen O’Neil (3:10:08) rounding out the podium.

Whitefish Marathon — Whitefish, MT | Friday, May 16

Scarlet Kaplan led the women’s race home in 3:03:07, followed by Taylaur Coccoli (3:16:28) and Elizabeth Fleming (3:24:45). Whitefish’s combination of beauty and competitive results makes it a perennial bucket-list marathon for runners in the Pacific Northwest and Mountain West.

♂ James Dugenet 2:27:46  |  ♀ Kari Hamilton 2:54:26  |  Finishers: 223  |  Avg: 4:22:10

Spokane’s Windermere Marathon was another high-quality Washington State showing, with 223 finishers and elite-caliber winning times. James Dugenet’s 2:27:46 was the third-fastest men’s winning time of the entire weekend, demonstrating that Spokane’s course plays fast despite its rolling terrain. Kari Hamilton’s 2:54:26 women’s victory was similarly excellent — one of the top five women’s winning marks across all events this weekend. Nick Braz (2:33:37) and Dylan Mason (2:36:23) completed a men’s podium full of sub-2:37 performances, while Brigid Carr (3:16:28) and Kristen Giombi (3:16:53) were separated by just 25 seconds for second and third in the women’s race.

Catie Hyatt won the women’s race in 3:35:32, ahead of Kate Birthright (3:41:36) and Seirena Richardson (3:46:55).

The women’s race was headlined by Jessie George, whose 4:06:20 winning time on terrain of this difficulty is a performance of considerable note, placing her ahead of Chelsea Conway (4:53:44) and Jackie Ellwood (4:58:47). A 6:26:21 field average tells the story of what the Grand Canyon of the East demands of its runners.

On the women’s side, Anniejoy Amuan (3:38:33) edged Paola Flores (3:40:30) and Renee Figueroa (3:57:30) in a competitive podium.

Deep in the Ozark National Scenic Riverways, the Berryman Marathon’s 6:42:36 field average was the highest of any race this weekend — a testament to the unrelenting, rocky singletrack that defines this Missouri trail classic.

♂ Adam Quinn 2:26:28  |  ♀ Emma Robidoux 2:55:46  |  Finishers: 50  |  Avg: 2:54:34

Perhaps the most statistically curious result of the weekend: the Sugarloaf Marathon’s field average of 2:54:34 appears to reflect a 15K or half-marathon component folded into the reporting, as a 50-person event producing a 2:54 average across a full 26.2-mile distance would be extraordinary. Regardless of distance, Adam Quinn (2:26:28) and Steven Fritzsche (2:27:03) dueled brilliantly down the famous Sugarloaf descent, finishing within 35 seconds of each other. Emma Robidoux won the women’s race in 2:55:46.
