You can climb to the top of the Hancock Building for a good cause on Saturday with the Greater New England chapter of the National MS Society's annual Climb to the Top fundraiser.

The climb includes 61 floors and 1200 stairs and hundreds of people will be participating.

You don't have to worry about being passed by quicker climbers though, the National MS Society breaks things down into three groups, General, Competitive and Firefighter.

The climb starts at 8 a.m. and goes until 2 p.m. at Clarendon Tower in Boston on Saturday.
