A group of gamers from Lafayette, Indiana have announced their second Mario Marathon in benefit of Child’s Play, an organization funded by the creators of Penny Arcade that brings toys and games to hospitalized children worldwide.

A team of three players will play through 25 years worth of Mario games across all Nintendo consoles. The event will start on July 10 and will end on July 15. The organizers hope that this event is bigger than least year’s, which gathered over $12,000 dollars for Child’s Play and lasted 57 hours. Viewers also have the opportunity to interact with the team and win Mario-related prizes.

The event is being broadcast online at www.mariomarathon.com, and will start on July 10 at 9:00 AM EDT.
