The May ultramarathon racing calendar closed with a bang for four Massachusetts women as they made their collective presence felt at the Cow Bone Trail Run in Maryland. Additionally, the New England classic multi-day event – Infinitus – challenged runners with a new venue and equally difficult trails. Both events closed out May on a high note and are featured in this edition of the roundup.

In this second roundup installment from the May 13-15 weekend we catch up on the non-New England races and journey to Georgia, Virginia, New Jersey and California.

Runners at the Big A 50K in Maine enjoyed comfortable temperatures and good trail conditions thanks to the benefit of the calendar – Big A was held on May 7. A week later, those who toed the line at Maine’s only 100-miler, the Riverlands 100, or any other races in the Northeast were far less lucky. Merciless conditions on May 14, from high heat to humidity, took their toll on runners at Riverlands, as well as those at Vermont’s Runamuck 50K. In this edition of the roundup we catch up with those New England events.
