Boston Qualifying Standard
3:05:00
You need to run 25m faster to hit the qualifying standard. To realistically enter, aim for 30m faster.
The BAA requires runners to meet the standard, but due to oversubscription, entry has required being ~5 min under the standard in recent years. The standard for men aged 35–39 is 3:05:00.
London Good For Age
2:50:00
You need to run 40m faster to hit the qualifying standard.
London GFA entries open annually. Check the TCS London Marathon website for the current year's exact thresholds and application window.
