Mid-September presented the busiest weekend of ultramarathon racing this year, with dozens of runners from Massachusetts and greater New England branching out beyond the Bay State to race throughout the country. This second of two roundups aims to recap results from the Sept. 10-12 weekend, with the top highlight coming from Cambridge resident Jenny Hoffman who threw down a women’s course record and the third-fastest time of anybody in history at the Pine Creek Challenge 100-miler in Pennsylvania.

Mid-September presented the busiest weekend of ultramarathon racing this year, with dozens of runners from Massachusetts and greater New England branching out beyond the Bay State to race throughout the country. This first of two roundups aims to recap results from the Sept. 10-12 weekend, with the top highlight coming from Cambridge resident Simon Guerard who successfully completed the Grand Slam of Ultrarunning with his finish at the Wasatch Front 100.

This week’s roundup is a bit of a catch-all, between out-of-state races during the Sept. 5-6 weekend, the late posting of August results from Twisted Branch, and the massive pile of results to sift through from the Ultra-Trail du Mont-Blanc. We’ve tracked them down, though, and have them included in this week’s roundup.

As the summer ultramarathon racing season nears its final weeks, New England runners traveled from coast to coast to take part in a mix of new events and long-time classics. From top-25 finishes at the high-altitude Leadville Trail 100 in Colorado, to the Bigfoot 200 in the Cascade Mountains of Washington, to the Mountain Lakes Backyard Ultra in nearby New York, and more, there’s plenty to read in this week’s roundup. Additionally, several local runners also raced the Twisted Branch 100K in New York, though results from that race aren’t yet available.
