For the past two years, runners aiming for the Boston Marathon have faced a significant challenge: simply meeting the Boston Marathon qualifying (BQ) times hasn’t been enough to earn acceptance into Boston. To secure a spot, runners had to finish more than five minutes faster than their BQ times—5:29 faster for the 2024 Boston Marathon and 6:51 faster for the 2025 event. In response to this trend, the Boston Athletic Association tightened the BQ standards by five minutes for all age groups below 60-64, effective for the 2026 race. It's anticipated that these fast acceptance times will continue in 2025 and runners vying for a coveted spot in Hopkinton will need to exceed the adjusted BQ times by more, making the path to Boston even more competitive.
Regardless of the acceptance times needed for the 2026 or 2027 Boston Marathon, runners must identify fast, well-organized races that give them the best shot at achieving a BQ. To help, we’ve compiled the 50 Best Marathons to Qualify for Boston in 2025. These races are known for their PR-friendly courses and are excellent choices for those chasing their Boston dreams.
