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.
To compete in the London Marathon as a male elite runner you need to be able to run a marathon in under 2 hours 45 minutes (sub 3.15 if you are female). No small feat. But plenty elite runners manage this each year and are in with a shot of claiming victory. The World Marathon Majors compiles the big 5 city marathons (Boston, New York, Chicago, Berlin and our favourite London). In order to qualify you must score in the top 5 in at least 4 of these events. Again, no small feat.
