Spalding Autograss Club was forced to cancel its most profitable meeting of the year after its field was vandalised in the early hours of Saturday.
Officials estimate it will cost £2,000 to put right damage to equipment including its entry gate, Armco barriers, telegraph poles, heavy duty wire rope, chicken wire, start line system and expensive electrical wire for a public address system.
The attack also meant the club was forced to cancel its big race meeting on Sunday, which included a fundraiser for Macmillan Cancer Support.
The club has sourced CCTV footage from premises in the area of their track at Hurdletree Bank, Holbeach, and have passed it to the police.
Members are also appealing to the public to call police on 101 if they know who was responsible for the wrecking spree.
Club chairman Chamelle Clayton says someone on an old school, single wheel drive tractor broke into the field at about 5.30am.
She said: “We were expecting to have a good income from our Sunday meeting – about £1,700 – and this evil individual has destroyed our track.
“We are absolutely livid and disgusted that someone has ruined our track that has been going many years.”
She said race meetings only go ahead thanks to volunteers and everyone involved with the club is devastated.
Club secretary Brian Barrs said: “I feel absolutely gutted.”
The club has been around for half-a-century. It has 50-60 members and they are holding a meeting tonight (Wednesday) in The Swan pub at Moulton to talk about the steps they must take to get their equipment repaired so they can race again.
Chamelle said they hope to be back in action by October 30, but that’s not confirmed.
