As part of the partnership between the Porsche GT3 Cup Challenge Brazil and the Instituto Ronald McDonald 30 children were welcomed into the Curitiba paddock.

Driver Charles Reed's Porsche will carry the colours of the McHappy Day scheme, which raises funds for the treatment of cancer in children and teenagers.

“It’s very cool to see these children enjoying it,” said Reed. “I had a nephew who faced cancer when he was 13. I know how difficult it is for everyone, including friends and family. It’s great to work with an action that allows early diagnosis and medical treatment for these and other young people.”

In total the series welcomed 60 guests – patients, caregivers and doctors – got the opportunity to get up close to Reed's race car.

“I like to watch races on TV but this is the first time that I follow closely. The cars are beautiful,” said 16-year-old Timothy, one of the children given the chance to sit in the cockpit of the Porsche.

The logos of the McHappy Day scheme also appear around the Curitiba paddock, as well as on decals on the front of all the Porsches in both the Cup and Challenge series racing at Curitiba this weekend.
