2013 Boston Marathon First Aid Walking Team Boston - Commonwealth Ave. from Hereford St.

Red Cross Marathon Race Course First Aid Walking Team, 'Fox-2-6-alpha'*. Here, volunteers EMT-Basic/Ski Patroller/Firefighter Brian C. (L) & Ham Radio Operator Bill head west toward our station (F26) on Commonwealth Ave. from Hereford St., the famous right turn to Boylston St. and the finish line. I'm part of the Walking Team and taking up the rear while shooting photos like this one at 12:42 EST.

*A "Go-Team" or "Walking-Team" usually consists of personnel from a first aid station, usually an EMT, a first responder or first aid/CPR certified volunteer and an emergency communications ham radio operator. 

Go-teams are dispatched to official and unofficial reports of a "down runner" or other medical need along the route on either side of the station. "Walking Teams" routinely go a 1/4-mile or so from the station as a medical support presence for athletes, law enforcement, spectators and course officials on the race route.- JCG
