RECENT heavy rains have dampened the spirits of Castle Hill BMX Club members, who need the rain to go away for at least four more days.
Club secretary Michael Carruthers said that's how long it would take to finish digging four new race courses ahead of their annual open day on September 21.
"They had just started to dig up a brand new corner of the track when the deluge happened on Saturday night," he said.
"Water is being pumped out [of the existing tracks], but as fast as they're pumping it's refilling and the [hired digging] equipment is just sitting idle."
He said up to 500 riders, ranging from four to adult professionals, are expected at their open day — planned as part of the Orange Blossom Festival, and the largest event on the club's calendar.
"That's at least 2000 spectators," Mr Carruthers said.
The club's $10,000 track upgrade includes a new spectator stadium.
Mr Carruthers said The Hills Council had generously permitted the club to use truckloads of dirt from its road works on Samantha Riley Drive, Kellyville, to complete their track.
