Patriots' Day weekend has officially opened in Boston with Saturday morning's BAA 5K, the traditional curtain-raiser for the 130th edition of the Boston Marathon. Several thousand runners swept through Boston Common, down Commonwealth Avenue and across the famous Boylston Street finish line with just over 48 hours on the clock until the elites leave Hopkinton. The event has grown into one of the largest 5km road races on the American calendar and functions as an unofficial homecoming for the wider Boston Athletic Association community, with past marathon champions, elite shakeout groups and charity runners all gravitating to the early-morning start line.
The elite fields for Monday's marathon are largely in town. Defending men's champion John Korir and American record holder Conner Mantz were spotted at Friday's media availability at the Fairmont Copley Plaza, the traditional host hotel for the pro field. Sharon Lokedi, the women's course record holder at 2:17:22, arrived in the city earlier in the week and completed a low-key shakeout along the Charles River path on Friday morning. Eight of last year's top 10 finishers are returning to Hopkinton, including 2025 world championship gold medallist Alphonce Felix Simbu, and 25 entrants in the men's field own career bests under 2:07 — a statistic the BAA has used to promote the depth of what it considers one of the strongest Boston assemblies of the modern era.
The John Hancock Sports & Fitness Expo at the Hynes Convention Center is running through Sunday afternoon, and the queue stretching down Boylston Street on Friday morning underlined just how busy the weekend is expected to be. Organisers have confirmed that bib pickup closes at 6pm on Sunday, with no race-day collection available, and have continued to encourage runners to pick up early to avoid crowding. The BAA Invitational Mile, a street event along a closed-off Boylston Street finish chute, is scheduled for Sunday afternoon and will again bring Olympic and world championship milers to the heart of the city 24 hours before the marathon itself.
The forecast for Monday has firmed up into one that runners will welcome and spectators may not. Temperatures in Hopkinton are expected to sit in the mid-30s Fahrenheit at the 6am staging, climbing only into the upper 40s along the course by the time the final runners reach Boylston. A north-westerly wind in the 10-15mph range, gusting to around 30mph, will provide a quartering tailwind through much of the point-to-point course, a condition widely regarded as the closest thing to a free gift that the Boston route offers. Relative humidity will drop from about 50 per cent at the start to 20-30 per cent through the afternoon, reducing the thermal load on runners even as the sun stays high.
For the six-wave marathon itself, start times run from 9:37am for the elite men and wheelchair field through to 11:15am for the final corral. Road closures along Beacon, Commonwealth and Boylston begin before dawn on Monday, with the Red Line and Green Line offering expanded service from mid-morning to handle the influx of spectators. Organisers have once again emphasised that spectators should layer up on a day that may struggle to reach 50°F in Copley Square. Two days out, every metric — the weather, the depth of the elite field, the sell-out expo and a sharpened Boylston finish chute — points to a 130th Boston Marathon that is ready to run.
