What the PDF prints
Main Street in Hopkinton, Route 135 through Ashland, Framingham, Natick, and Wellesley, then Route 16. Right at the Newton fire station onto Commonwealth Avenue, the Newton hills, Chestnut Hill Avenue to Cleveland Circle, left on Beacon Street through Brookline and Kenmore, right on Hereford, left on Boylston, finish near the Boston Public Library.
Fluid stations every mile. Maurten gels at miles 12, 17, and 22. We are not turning that sheet into an elevation chart. The 247 m gain and 149 m high point already in this record were not in the PDF.
What we will not pretend
No course atlas. The PDF has a drawn map and no coordinate file. Wave clocks in the volunteer section of that PDF stay in 2026.

The qualify page, opened 4 November 2026, dates the race 19 April 2027 and says qualifier registration closed on 18 September 2026. The cutoff for acceptance was 5:17 under the age-group standard. The course description is the B.A.A. Race Course PDF uploaded March 2026. That file is not labeled 2027, and it has no GPX. Wave clocks in the PDF are not copied here.
