BELFAST — After essentially being grounded previously due to the pandemic, the in-person “Bug Run” 5-kilometer run/walk made a triumphant return to the city’s downtown and waterfront areas with electric performances and an incredible push for first among several runners, including a former professional triathlete and recent Olympic Trials participant.

Ultimately, Ryan Callahan, 28, of Castine, and Lauren Hurley, 33, of Belfast pushed the top group of runners hard over the tough, hilly course on Saturday morning, Aug. 14 in the Rotary-sponsored event before the two pulled away down the stretch.

In fact, both elite runners finished with blistering-fast times, as Callahan outsprinted Hurley in the final downhill portion of the 3.1-mile course to win the event — which had 85 registrants and 72 finishers — by five seconds.

Callahan finished in 15:54 and Hurley in 15:59 (not far from her best 5K time of 15:45).

Hurley, a former professional triathlete, and her husband, Matt, 37, a native of Belfast (who finished fourth on Saturday), were visiting the area and decided to participate in the race.

Lauren, who competed in the 10,000 meters (6.2 miles) on June 26 at the Olympic Trials in Eugene, Ore., where she finished 17th, said she thought she would sign-up and was enticed by winning pounds of lobster.

“I actually felt pretty good,” she said, adding she has not “properly” trained since the Olympic trials in June. “I have been enjoying some down time, so I didn’t know if I would be good and I was really surprised to see two fast guys here racing. It was a great course. It was really fun, actually. One my more enjoyable races.”

Lauren, who has a one-year-old son, Wilder, said she had a solid performance in the Olympic qualifier, but it was hot. She was ranked 38th in the 10,000 meters and placed 17th, but did not qualify for the Olympics.
