The Massachusetts ultra calendar for 2026 has been updated with all of the info that I have so far. I still need to add links to registration pages for each event. I will continue to update as I get more information. Over the next week or so I will also update the calendar of ultras for other New England states.

The following table lists the ultramarathons in Massachusetts. Know of an ultra that’s missing? Let us know at [email protected]. 2026 MASSACHUSETTS ULTRARUNNING CALENDAR DATE – ULTR…

After a 25-year run as the G.A.C. Fat Ass 50K, Gil’s Athletic Club handed off the reins for the classic New England ultrarunning kickoff event to the Trail Animals Running Club. The first offering …

Jason Kaplan closed out the 2025 New England ultrarunning season with a winning effort at the West Rock Winter Fat Ass Extravaganza in Connecticut, and Cole Crosby ringed in the new year with a sizzling 200+-mile effort over 48 hours at Across the Years in Arizona. These are just a few of the highlights for New England ultrarunners from the final days of 2025 and first moments of 2026 that we have featured in this edition of the roundup.

"It’s hard to believe this column closes out year 10 of this journalism passion project. I had no idea it would last this long. I had no expectation that people would want to follow along each week, or that many folks would tolerate being bugged by me for interviews. The reception surpassed my wildest expectations, and it has fueled my fire to stay curious, keep reporting, and continue telling stories year after year."

Read on for more of the annual end-of-the-year column from MassUltra Editor Chris Wristen.

I’d lived in Massachusetts less than six months when I launched the MassUltra website in January 2016. I only knew a handful of people, a couple of local trails, and had yet to run a trail ultramar…

It would have been understandable if Wayne Ball turned his focus to next year the moment his name was selected in the Dec. 6 lottery for the 2026 Western States Endurance Run. After all, he waited eight years for his chance to participate in trail ultrarunning’s original 100-mile race from Olympic Valley to Auburn, Calif.

Instead of worrying about Western States – there will be plenty of time to do that between now and the June 27-28 race – Ball channeled his excitement into one final race for 2025: Seth’s Fat Ass 50K. Rather than participating as a runner, Ball is the race director for the event, which took place Sunday, Dec. 20, at Forest Park in Springfield, Mass., and was the final ultramarathon of the year in Massachusetts. The timing of the event allowed him to celebrate his lottery success by giving back to his local running community and helping others achieve their goals.

A New England trail- and ultrarunning classic event will return in 2026 after all.

Barely a month ago Gil’s Athletic Club announced that its popular G.A.C. Fat Ass 50K would not return following a 25-year run as the region’s official kickoff to the new trail- and ultrarunning season; now, the event has been revived by the Trail Animals Running Club.

The second-to-last New England ultramarathon of 2025 took place on Saturday with the annual running of Seth’s Fat Ass 50K in Springfield, Mass. We’ll have that covered in a separate story, but here in this week’s roundup we catch up on how runners from the region fared at other ultras throughout the United States during the Dec. 20-22 weekend. Only a handful of runners traveled for pre-holiday ultras, but they turned in some strong performances. None were better than Vermont’s Eric LiPuma and Joanna Fortier who earned victories at the Cave Creek Thriller in Arizona. Their winning efforts lead off this edition of the roundup.

The final weeks of 2025 are upon us, and New Englanders are squeezing in a few final ultramarathons to close out the year. During the Dec. 13-14 weekend, that included a pair of events in the region, with the inaugural Left Nut 50 in Rhode Island and the eighth annual Jingle My Frosty Balls 8-Hour in New Hampshire. Results of the latter were unavailable, though dozens of runners took part and the event raised $320 for local charities. Beyond New England, runners from the region stayed in the east, venturing to Florida and Pennsylvania, as well as North Carolina – where Connecticut’s David Stawski closed out a dozen 100-milers in a dozen months at Beast of the East. We have it all covered in this edition of the roundup.

As the saying goes, absence makes the heart grow fonder. To put that theory to the test, the Trail Animals Running Club brought back a popular distance at the TARC Winter Classic to close out the 15th edition of the TARC Trail Series on Saturday, Dec. 6, at the Middlesex Fells Reservation in Stoneham.

Read on for more from the Trail Animals Running Club (TARC)'s . Also, a big thanks to David Metsky for the assist with photos!

The 2025 ultrarunning season is rapidly coming to a close. Here in New England, the Dec. 6-7 weekend saw a few final events play out, including in Massachusetts with the final race of the 2025 TARC Trail Series with the TARC Winter Classic at the Middlesex Fells, as well as in Connecticut at the Tower Tag Challenge 8-Hour and up north in New Hampshire at the Krampuslauf 9-Hour. We’ll have the TARC Winter Classic covered in a separate recap, but here in this week’s roundup we catch up on Krampuslauf and Tower Tag, as well as other ultras throughout the United States where New Englanders secured late-season finishes.
