• Fall, 2008 – Les Judd and his wife Pamela watched The Amazing Race on TV and had the idea to host an event in New York City called the Amazing Green Race. It would center around everything green in NYC.
  • January, 2009 – First organizing meeting of the Amazing Green Race of NYC.
  • February, 2010 – Green City Challenge was established as a not-for-profit, tax exempt organization. The name of the organization changed to avoid any legal issues.
  • October, 2010 – The first Green City Challenge Race took place in Lower Manhattan. Ten teams of two people each raced around Lower Manhattan on bicycles to different locations where they had to perform challenges related to sustainability.
  • October, 2011 – The second Green City Challenge Race took place.
  • 2012 2013 – Green City Challenge went through a reorganization.
  • 2014 – 2016 For three years in a row, on a Sunday in the month of October, Green City Challenge organized an annual Green City Challenge Eco-Carnival at La Plaza Cultural in the East Village. At the Eco-Carnival, Green City Challenge presented several fun, interactive, hands-on games that taught people about sustainability. Each year, the number of attendees of the Eco-Carnival increased. By 2016, the Eco-Carnival was a very successful event with approximately 200 attendees and volunteers.
  • 2017 – The Board of Directors decided to change direction again. Although, the Eco-Carnival was a very fun and educational event, it was not impacting a large number of people. The Board of Directors wanted to bring the Green City Challenge games into public schools in New York City. We thought that bringing the games into schools would have a greater impact than the Eco-Carnival could ever have. 
  • Spring, 2019 – Present – Green City Challenge is bringing our games into public schools. Currently, the focus is on Middle Schools in the Bronx and Manhattan. The games we have created are perfect for kids in grades 5, 6, 7, and 8, but kids that are slightly younger or slightly older enjoy them as well. When kids play our games, their faces light up! They truly enjoy them and learn a lot about sustainability in ways that they do not learn in the classroom.
