Puerto Rican comedian Raymond Arrieta is on a six-day walk across Puerto Rico to raise money for the Oncological Hospital.

The first stretch of the walk, which began Thursday at Pedro Montañez Municipal Stadium in Cayey, a city in central Puerto Rico, ended 27 kilometers (17 miles) down the road at the University of Turabo in Gurabo.

"The pain began in my heels and under a big toe, which is where it always hurts a lot," the television host told reporters after finishing the first stretch of this sixth edition of "Give life walking with Raymond."

The walk will continue Friday from the University of Turabo to the 26-kilometer (16-mile) marker.

The biggest challenge of the walk is the 24-hour route that will kick off at noon Monday and will pass through the municipalities of Toa Baja, Bayamon and Guaynabo, to wind up at the parking lot of Telemundo's Puerto Rican studios in the capital's Hato Rey district.

Puerto Rican artists like Daddy Yankee, Luis Fonsi and Amaury Nolasco have joined Arrieta on his benefit walk.

Last year the event succeeded in collecting hundreds of thousands of dollars to help cancer patients in Puerto Rico. EFE
