Wisconsin 10-year-old ran 1:37:15 for 13.1 miles on Saturday.

Noah Bliss, a 10-year-old from Kenosha, Wis., set a new age-group world record in the half marathon at the sixth annual Wisconsin Marathon on May 3. He finished the course that runs along the Lake Michigan shoreline with a gun time of 1:37:15. That’s the fastest time ever recorded by any 10-year-old in the world according to the Association of Road Racing Statisticians (ARRS), an international organization that tracks single-age world records for road races.

“This race was his first half marathon three years ago and it’s become a tradition for him and our family,” says Monica Bliss, Noah’s mother. “He had a lot of fun running the race and finished in a great time. He was ecstatic when he finished because he shaved so much time off his PR from last year, but he had no idea that he was setting any sort of record. When Noah found out about the record, he was speechless.”

Three criteria determine whether or not the ARRS will accept a record. In order to qualify, the course must be certified and cannot have a start/finish separation greater than 30 percent, nor can it drop more than one meter per kilometer. The ARRS only accepts gun times and must confirm the runner’s age at the time of the performance using his or her date of birth. Bliss’s age and time, along with the race’s course, met all of these standards.

Bliss finished 71st overall in a field of over 2,000 half marathon runners.

“We are so happy for Noah and his family,” Jonathan Cain, race director of the Wisconsin Marathon and Half Marathon, said. “The fact that he was able to break the record on our course is exciting for us as well and shows how Noah has progressed over the years as a runner.”

Logan Beausoleil of Davenport, Iowa broke the half marathon course record, finishing in 1:12:31.Kristine Juno of Highwood, Ill., won the women’s division of the half marathon in 1:26:16. Aaron Viets of Rolla, Mo., and Fiona Carlon of Chicago took home individual titles for the concurrent Wisconsin Marathon with times of 2:34:58 and 3:07:48, respectively.

In February, Will Stone of Largo, Fla., set a new 9-year-old boys half-marathon world record of 1:41:07 at the Gasparilla Distance Classic in Tampa, Fla. Last October at the Showdown Half Marathon in Fairview, Texas, Keelan Glass set a new 6-year-old girls world record of 2:46:31.
