Amid the usual heat surrounding the Ohio State-Michigan game, fraternity brothers from the two schools will reunite in an annual football relay to fight cancer.
About 240 men will run two game balls to Saturday's contest at Michigan, taking 15-minute turns along a 186-mile route from Columbus.
The Phi Gamma Delta and Pi Kappa Alpha fraternities hope to raise $100,000 for the American Cancer Society.
Ohio State students will begin the fourth annual Rivalry Run at 3 a.m. Friday and are expected to hand off to the Michigan guys 15 hours later at the halfway point, in the northwest Ohio city of Findlay.
The relay is scheduled to end in Ann Arbor at 9 a.m. Saturday, three hours before game time.
