Matthew Broderick and wife Sarah Jessica Parker are packing their bags (and 5-year-old son James Wilkie) and crossing the Atlantic for a late summer getaway to Ireland.

“My family and I are staying out here until the middle of August, and then we are all going to Ireland together,” Broderick told PEOPLE Saturday at the A.L.S. spin-a-thon in Amagansett, N.Y.

The Producers star joined Katie Couric, Alec Baldwin and almost 100 Long Island locals on stationary bikes to raise awareness and funds for Lou Gehrig’s disease, Alzheimer’s and other brain-related illnesses.

30 Rock star Baldwin and Broderick – who guest-starred on an episode of Baldwin’s series earlier this year – were both decked out in cycling pants, white T-shirts and visors. The duo spun at the front of the crowd, chatting and laughing together throughout the two-hour event. To counter any calories burned, the pair then visited the barbecue spread, where they ate and chatted with other participants.
