Walk, bike, or carpool: Take the challenge!

Building on the success of past bike-or-walk-to-work days, the New Hampshire Bike-Walk Alliance has expanded the annual event to an entire week this year, from May 11 through May 15.

The project challenges Granite Staters to use human power to get around as much as possible during the week.

In keeping with the "green" theme, organizers note that transportation is responsible for an estimated 40 percent of New England's carbon dioxide emissions, and encourage folks who can't walk or bike to carpool or take public transportation.

Check out the local events

Communities around the state have planned celebratory events, which range from meet-and-greet breakfasts to free fares on public transportation.

All participants can also qualify for raffle prizes, including the grand giveaway of a one-night stay and breakfast for two at the Mount Washington Hotel. To qualify, you must fill in the online form.
