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.
Finishing times for marathons (26.2 miles) range from a little over two hours for world-class, elite marathoners to 8+ hours for walkers. In terms of average marathon times, the median marathon finishing time in 2015 for men in U.S. marathons was 4:20:13 (9:55/mile pace), according to Running USA. The median finishing time for women was 4:45:30 (10:53/mile pace). Before running your marathon, it's definitely helpful to have an estimate of your marathon finishing time, so you know how to pace yourself properly.
