Dueling with Jynocel Basweti over 26.2 miles, said Michael Wardian, is invariably an all-or-nothing proposition. “Either he’s going to crash and burn or he’s going to run pretty well,“ Wardian said. “Today he ran pretty well, I guess.“ Basweti, a 22-year-old Kenyan, became the SunTrust Richmond Marathon’s first back-to-back winner in five years by delivering an elegant effort yesterday in raw, windy conditions. He finished in 2:18:28—the sixth-fastest time in the event’s 32-year history—and defeated Wardian, the runner-up, by nearly seven minutes.
