Three ultrarunners from the Truckee/Tahoe area kicked off the trail-running season with solid results in the Lake Sonoma 50 this past weekend.

Anna Mae Flynn, a 29-year-old Tahoma resident, raced to a third-place finish among women and was 17th overall in a field of 304 finishers. She covered the 50-mile course — an out-and-back circumnavigation of the Warm Springs Arm of Lake Sonoma — in a time of 7:28:22.

Truckee’s Peter Fain, 44, also finished among the leaders, placing 15th in 7:21:47, while Gretchen Brugman of Truckee crossed the finish line in 9:31:00, which was good enough for 21st place among women and 91st overall. Flynn, Fain and Brugman are all members of the Truckee-based Donner Party Mountain Runners club.

Jim Walmsley, 26, of Flagstaff, Ariz., won the race while setting a new course record in 6:00:52. The previous record was 6:09:39, set last year by Alex Varner.

YiOu Wang, 31, of San Anselmo was the top woman and 13th overall with a time of 7:14:45. Stephanie Howe — winner of the 2014 Western States Endurance Run — owns the women’s record of 7:08:23, which she set in 2015.

The Lake Sonoma 50 course consists of rolling hills with three significant climbs and about 10,500 feet of elevation gain and loss.

Flynn, who was the top woman in the 2014 Donner Lake Triathlon, also showed her prowess this past February in a less familiar endurance endeavor — snowshoeing. A relative neophyte to the sport, she picked up some pointers from Fain — a former national snowshoeing champion — before winning the women’s 10K at the United States National Snowshoe Championship in Ogden, Utah.
