Conditions at the start in Hopkinton were closely watched this morning, with race officials and runners monitoring temperature, wind, and humidity ahead of the first wave. The Boston Athletic Association confirmed all waves departed on schedule, sending a sea of runners through the historic New England landscape.

Elite fields in both the men's and women's open divisions are stacked with international talent this year, alongside strong performances expected from wheelchair and adaptive athletes. Course records are always a topic of conversation at Boston, where the rolling terrain and unpredictable weather can make or break a runner's day.

The halfway point in Wellesley is legendary for its "Scream Tunnel," where students line the course and provide a wall of noise that competitors often describe as a physical force. Runners reaching this stretch can expect one of the loudest and most energizing moments of their race.
