While most of the New England running community eyed the upcoming Boston Marathon, some hearty ultrarunners from the region had their hearts set on running technical trails during the April 17-19 weekend. Some tackled the 30th edition of the Trail Animals Running Club’s “Don’t Run Boston” 50K and 50-Mile races on Sunday, April 19, at the Blue Hills Reservation. We will have that covered in a separate recap. But we lead off this week’s edition of the roundup with another tough New England race – the Traprock 50K in Connecticut, which saw prior champions reign again, on Saturday, April 18. Then we catch up on how New Englanders fared beyond the region as we catch up on results from New York, Pennsylvania, Arizona, California, and Missouri.

The April 10-12 weekend was hopping for ultramarathons in New England. A pair of events took place in Massachusetts – the Spring Fever 8-Hour in Hingham, and The Next Loop Endurance Challenge in Wrentham – both of which will be covered in separate recaps. Additionally, the region rejoiced with the return of the Runamuck 50K in Vermont following a two-year hiatus. The record-setting day at Runamuck leads off this edition of the roundup, but we also catch up on results for New Englanders at other races across the country, including in Virginia, Utah, California, Oregon and Illinois.

The 2026 ultramarathon season in New England is starting to heat up. The April 3-5 weekend saw the first of four straight weekends with an ultra in Massachusetts as the Mt. Toby 50K took place in Sunderland. We’ll have that covered in a separate story, but here in this week’s roundup we are catching up on results from around the region and beyond. In Connecticut, the inaugural CT123 – a 200K journey across the state – took place. Additionally. We catch up on Maine resident Jason Geroux’s successful completion of the Arizona Monster 300-miler, and close out at the Fort Yargo Ultra 50K in Georgia.
