Boston Monday: It's going to cool fun! Gear list

Really looking forward to my 5 or 6th Boston. Had a 25 year gap in there. The weather should be cool, good for me. Not much of a fan of the course but will try for once not to go out to fast!  Love the crowds, the organization, the tradition. Had the goose bumps at the expo yesterday seeing so many fit and fast runners of all ages from all over the world. The Marathon and I am lucky and grateful
