NEW YORK (AP) — James Blake had success at another iconic New York sporting event.

The retired tennis star finished the New York City Marathon in 3 hours, 51 minutes on Sunday.

“It’s a little different, but both are amazing,” Blake said of playing in the U.S. Open and running the marathon. “Here they are cheering for so many people. The Open they are cheering for just you.”

He was greeted by his family at the finish line as well as two-time Australian Open champion Victoria Azarenka, who had promised on Twitter to bring Blake a milkshake when he finished.

The 35-year-old, who was known on the court for his quick, high-intensity style, said earlier in the week that endurance running was something new for him.

“I had fun, but will leave this for the professionals,” he said. “I was nervous at the start and halfway through didn’t think I’d make it under four hours.”

Blake was running for his foundation, which raises money for early detection cancer research at Memorial Sloan-Kettering Cancer Center.

He was in the news in September when he was standing in front of a Manhattan hotel and a New York Police Department officer grabbed his arm and tackled him to the ground in an arrest caught on surveillance video. Police said Blake, who was ranked as high as No. 4 in the world before retiring after the 2013 U.S. Open, had been mistakenly identified as a suspect in a cellphone fraud scheme. The mayor and police commissioner have apologized to Blake, and the city’s police watchdog agency has substantiated the excessive-force complaint Blake filed.
