90-year-old woman sets U.S. half-marathon age-group record

October 3, 2023

Just months after blazing to a new world age-group standard in the 1,500m, 90-year-old Dot Sowerby has broken the U.S. half-marathon age-group record, underscoring her message that age isn’t an obstacle to breaking down barriers.

The grandmother and longtime runner from Greensboro, N.C., completed the 2023 Life Time Chicago Half Marathon in 3:33:47, breaking the former 3:46:56 record set by Harriette Thompson six years ago at the Rock N’ Roll San Diego Half Marathon at age 94. (That effort by Thompson months before her death in 2017 still makes her the oldest woman on record to have completed a half-marathon, a record previously set by Canada’s Gladys Burrill in 2012 at age 93.)
