I'm always amazed by people's sacrifices and unselfishness when it comes to do things for a good cause. Eric Gelber is one such person. He takes on some crazy challenges to raise funds for the MMRF. He has raised hundreds of thousands for the MMRF over the years. From Sept 16 to the 18th, he will be running 200 miles in Central Park in NY with the goal of raising $250,000. Here's a short video of Eric discussing his journey and why he does what he does.
