The Memorial Day weekend ultra-trail calendar delivered a fixture-thick three-day block across North America, with 46 ultras counted on the UltraRunning Magazine race calendar and results filtering through from Oregon, Ontario, Wisconsin, Arizona and Texas through Monday evening. Mild Pacific Northwest weather and a damp Great Lakes corridor framed the headline finishes, with three races producing course-shaping wins and a handful of newer events landing record fields in their second or third editions.
The Stumptown Trail Runs in Portland, Oregon, delivered the headline North American 50km of the weekend with Kelly Flaminio winning the women's race in 5:22:37 and Ajay Hanspal taking the men's title in 3:51:42 on a wet Forest Park course. Flaminio, a Bend-based ultrarunner who finished sixth at Way Too Cool earlier in the year, told organisers she had targeted Stumptown as her last sharpening race before a switch to Lavaredo's 80K block in late June.
Up the trail in Hamilton, Ontario, the Sulphur Springs Trail Race returned for its 32nd edition with Owen Lane leading the men's 100-mile field through to a 17:38:17 finish, a near-thirty-minute margin over second on a course that has produced six sub-eighteen-hour winning times in the last ten editions. In Wisconsin, the Sugar Badger Trail Races delivered Andrea Stabelfeldt to a 7:30:39 women's 50-mile win, with Erl Martin taking the men's race in 6:07:36 ahead of a 162-finisher field that registered a record turnout for the event's third running.
Beyond the headline three, the weekend produced a smattering of mid-distance landmarks. Arizona's Mogollon Monster 100 produced a 22:14 winning time on a course that had been rerouted around late-spring snow on the Highline Trail, while Texas's Capt'n Karl's Pedernales Falls 60K saw Jordan Edwards take the women's race in 5:52, breaking the previous course record by nine minutes. Trail conditions in the Mid-Atlantic were softer than expected on Massanutten's still-fresh route, with finishers from last weekend's 100 mile reporting that runnable miles increased by Sunday afternoon.
The weekend serves as the unofficial closure of the early-summer block before attention swings to Western States 100, Lavaredo Ultra Trail and the UTMB World Series majors of June. Cocodona 250 winner Dan Green, who has been confirmed this week as a Hoka sponsor-entry replacement at Western States, sat out the weekend; Katie Schide remained in the Alps preparing for a Sierre-Zinal opener. Race calendar load shifts decisively to the European Skyrunner block from Saturday with the Mont Blanc Marathon weekend opening on 6 June.
