In running, BQ stands for Boston Qualifying time, which is the time a runner must achieve in a qualifying race to be eligible to register for the Boston Marathon. The qualifying time varies depending on the runners age and gender, and it is updated annually by the Boston Athletic Association. For example, the qualifying time for a 24-year-old woman is currently 3 hours and 30 minutes. Achieving a BQ is a significant accomplishment for many runners, and it is often considered a bucket list goal. It requires months of hard work and dedication, including building stronger legs, practicing fueling strategies, and proper pacing.
