Officials at the London Velodrome say three minor leaks have been spotted in the roof of the venue in the Olympic Park, but that they won't disrupt events.
They say the track, made of Siberian pine wood, has not been damaged by the water and that competition will continue as planned.
Organizers said that water came through three different places above the center of the arena, adding that repairs should be completed overnight.
Nicknamed the "Pringle" because of its crisp-like shape, the 6,000-seat, 94-million-pound ($NZ179 million) Velodrome is one of the signature venues of the Olympics.
The venue's designers worked with a panel that included multiple Olympic gold medalist Chris Hoy to create a record-breaking track.
