Ms Jones said the club hadn't been able to use the track for competition since February 12, its Tuesday club nights having since been held on the grass track at Hastings Boys High School.
Children's athletics had been able to continue with little disruption, the major effects being on training for elite older athletes preparing for the national track and field championships in Hamilton on March 17-19.
The Hawke's Bay Gisborne track and field championships had also had to be rescheduled, and the track had been unavailable for school sports in the lead-up to the East Coast North Island secondary schools championships on March 8.
While the park trust and Te Matatini organisers did what they could to enable some training to continue during the preparation of the park for the festival, athletes were unable to train on the park in some of the disciplines such as middle-distance running, javelin and hammer throw.
Ms Jones said while the club had been told of plans for the festival to be held at the park at an early stage, it was only about six months ago that it realised the impact it would have.
"I think we probably thought we would be without the track for a week and then be back," she said.
The club is still not sure when the track will be available for full use but she is hopeful its Tuesday club night next week will be back at the park.
"It [the festival] was good for Hawke's Bay, [it] just wasn't good for athletics."
