Kaka, a footballer, will run his first marathon in Berlin.

Kaka, a former World Cup-winning footballer, will make his marathon debut on Sunday in Berlin and said he was "just as enthusiastic" as he used to be before games.

Kaka, who played for Real Madrid and AC Milan before quitting the game in 2017, claimed that his father's battle with COVID-19 was what spurred him on to complete the marathon.

At the Berlin marathon press conference on Friday, Kaka stated that the patient spent 45 days in the hospital.

"Thankfully, he is here with us today."

The marathon will be a "family adventure" for Kaka's father and brother.

He is only strolling; he is not going to run, but we wanted him to participate in this experience with us because it is more of a family activity.

Because amateurs and pros can compete side by side, Kaka claimed that marathons are particularly unique as sporting events.

"I'm quite happy... This is something that works incredibly well in marathons, although it's obviously very different from those guys (pointing to the professionals).

"I can run and compete against professionals as an amateur athlete.

"This is absolutely unique in marathons — I can claim afterward that the best one in the marathon ran this time, and I was running beside him."

Kaka expressed his desire to finish in less than four hours.

The 2002 World Cup winner continued, "I intend to run for about three hours and forty minutes; if I feel okay, maybe I can do more."
