CYCLISTS competing in an amateur race churned up grass at a Cheltenham park.
Pittville Park was left in "a lot of mess", with torn-up grass after members of the Western Cyclocross League headed to the open space for a meeting.
The wet weather has been blamed for leaving the ground too wet before the cyclists started their race.
Borough council bosses are now talking to the group about using the land for future events.
And the Friends of Pittville Park have asked users to leave the spot how they would expect to find it.
Judy Longhorn, chairman of the group, said she was pleased more people were using the park.
She added: "We like to see people having fun there and enjoying themselves.
"I don't want to be seen as an old curmudgeon but it cannot be left in a mess. When the weather has been like it has, people need a bit of forethought.
"We spend a lot of time making the park look nice. People need to be leave it as they wish to find it."
Cheltenham Borough Council is now considering how to repair the damage at the park.
Wayne Sedgwick, senior community ranger, said officers had already visited to take a look at what needed to be done.
And he said the authority was in talks with the Western Cyclocross League about future events in the park.
Mr Sedgwick added: "A local cycling group recently arranged to use Pittville Park for a well-established annual event.
"Unfortunately, it seems that some areas of the park have suffered which may have been partly due to the wet weather conditions.
"We have already visited the park and are deciding on the best course of action to take. We will be liaising with the group about this and arrangements for future events."
The Western League series caters for Cyclocross racers in and around Bristol. Its Cyclocross races are described as "great fun, short events, over easy off-road terrain."
Cyclocross used to be a traditional winter sport, but it is now an international sport in its own right. League organisers did not respond to requests for comment.
