This year he has enlisted the help of more than 60 renowned chefs, including Bobby Flay, Priya Krishna, Sandra Lee, Marcus Samuelsson and Andrew Zimmern, to attempt to set a new Guinness World Records record for the most people in an online sandwich-making relay.

Their title attempt will go down on Thursday, with portions airing on TODAY and the entire four-hour event streaming on TODAY All Day, the new service on Peacock and TODAY.com (Peacock is part of our parent company, NBCUniversal).

Throughout the relay, to raise awareness for those living with food insecurity, viewers are encouraged to donate and learn more about Feeding America and World Central Kitchen.

Each chef will build an original sandwich, which Guinness World Records defines as at least two traditional or classic ingredients, not including condiments, placed between two slices of bread. Each chef has to complete a sandwich meeting those specifications before the next chef can begin whipping up his or her sandwich.

It's the latest unique record attempt at Rokerthon, which began with Al's historic marathon weather report in 2014 and has also included a Guinness World Records title for the fastest time to report a weather forecast from all 50 states and the District of Columbia.
