In November 2014, Roker embarked on a "Roker-thon", in which he did a non-stop, 34-hour weather forecast on NBC, from 10:05 p.m. on November 12, 2014 until about 8:00 a.m. on November 14, 2014. The record-setting event was a fundraiser for the Crowdrise Campaign to benefit the military and USO. He held a "Roker-thon 2", this time reporting weather from all 50 states and Washington, D.C. during the week from November 6 to November 13, 2015, in support of Feeding America. From March 27 until March 31, 2017, he embarked on "Roker-thon 3", visiting colleges and setting a Guinness World Record at each one, such as the longest conga line on ice and largest human letter.
