Boston Marathon Qualifying Times. For amateur runners, some people use the Boston Marathon qualifying times (BQ) as a measure of a good marathon time. Only a small percentage of marathon runners achieve these times. To qualify for the Boston Marathon, men ages 18 to 34 must run 3:05 or faster, and women in that age group must run 3:35 or faster. After that, additional time is given to older age groups. The BQ time standards can change from year to year. To qualify, you must run a marathon that is one of the designated Boston Qualifier races. Many runners select one of the marathons with the fastest courses to attempt to earn a BQ time.
