LeBron's bikeathon: Miami Heat star LeBron James is headed back to his hometown of Akron, Ohio, on Monday, this time to lead a 2.6-mile bike ride through the cityâ€™s streets as part of his â€śWheels for Educationâ€ť initiative.
James and 20 high school students will pedal from the University of Akron to East High School where hundreds of students in the program will await them.
The bike ride will be the first event since the program underwent a name change from the King for Kids Bike-A-Thon. The initiative strives to improve the academic success of third-graders from single-parent households.
â€śWe felt it was time to change the Bikeathon to something that could be more educational at the same time,â€ť James told the Akron Beacon Journal. â€śWe feel great about it.â€ť
