New York's McCambley, 23, a former Westport resident, completed the race at Longshore in 20 minutes and 35 seconds. Brown, 15, finished second in 20:54. The top female was Wilton's Mary Zengo, 48, who crossed the finish line in 23:37 for a tenth-place result. Zengo holds the course record for females with a time of 22:40 set back in 1997.
"It was a pretty awesome race," said McCambley, who topped a field of 165 runners on a damp, rainy at times, morning. "Spencer really pushed it."
McCambley held a lead for the first mile only to see Brown pass him when he stopped near a family on the course to take care of his loose shoelace.
"They started laughing because I stopped and Spencer ran right past me," he recalled.
Brown maintained the lead for about two miles before McCambley seized control.
The conditions were favorable for participants with an overcast sky and cooler air than they had the previous week.
"It was pretty perfect compared to last week," said McCambley, referring to the hot and humid conditions of the 3.1-miler on July 6.
"That's one of the reasons I came," Zengo said of the cool conditions.
Zengo said she has been battling Lyme disease and hasn't been able to train as much as she normally would, but that didn't stop her from putting in a good performance.
"It was nice that it was cool but dodging the puddles was a little bit of a challenge," said Westport's David Allen, 43, who finished seventh in a time of 23:15.
Participants also liked the mostly flat course.
"The finish was great. It was all pretty much flat and downhill," Brown said.
Jeff Watson, 31, of Stamford, was third in 22:02. David Litoff, 52, of Lewisville, Colo. came in fourth in 22:06 and James Lewis, 15, of Westport, was fifth in 22:49. Rounding out the top 10 finishers were Piotr Kostyk, 23, of Bethel, 22:58 in sixth; Allen in seventh; Stephen Marsalese, 47, of Rye Brook, NY, 23:22 in eighth; Paul Greenberg, 52, of Westport, 23:34 in ninth; and Zengo in 10th.
Westport's top female finisher was 18-year-old Blythe Lewis, who came in 17th in a time of 24:47.
Jake McCambley, 20, joined his brother for the race and said it was encouraging to see his older sibling ahead of him.
"That was motivation for me to see him -- how he was going so fast," he said.
For some, it wasn't about fast times. Brookfield's Sara Belles participated with her husband and their 10-year-old up-and-coming runner.
"We thought it was a good family event," she said.
The next race in the series is the 4.1-miler set for Saturday at 8 a.m. at Compo Beach.
