Sunday's Boston Globe had an interesting article about the steps the organizers of the 113th Boston Marathon -- being run today -- are taking to make the race more environmentally friendly. This is a trend being seen in other US road races, too.
More than 26,000 runners (from all 50 states and 60 countries) can create quite an environmental impact. In addition to the carbon used to get to Boston -- flying, driving, etc. -- they're bused to the starting line in Hopkinton, Mass., using approximately 22,400 pounds of Co2. They will use an estimated 1,400,000 cups, more than 62,00 water bottles, and 28,00 mylar blankets (today's high in Boston is predicted to be 48).
How do you begin to green up those numbers? First, the Boston Athletic Association is using diesel fuel in the buses that transport the runners, and it bought 22,440 pounds of carbon emission credits to offset the impact of the busing. They're also using electric scooters (instead of traditional motorcycles) to lead the runners.
