Thunder, lightning and torrential rain came down around 6 and 7 a.m. from Hopkinton to Boston. That forced State Police to stop the convoy of buses bringing runners to the starting line on the Massachusetts Turnpike. They waited at the Framingham rest stop for the bad weather to pass before moving on and arriving in Hopkinton just before 8 a.m.

Wave one runners and B.A.A. volunteers who were already in Hopkinton at the start of the storms were forced to wait inside Hopkinton schools until it was safe to go outside.
