Name me a 'big fish' that isn't losing money this season. Poole opt for Championship racing for primarily financial reasons ie not losing money. Not owning their own stadium Poole get no revenue from any stadium outlets. Their income derives solely from admissions, sponsorship and advertising by providing successful, trophy-winning teams within a financial budget, whilst attracting decent crowds. Simples.
Promoter Matt Ford has recently stated publicly that Premiership racing might only be an option for Poole if there is a decent TV contract plus being allowed to race at home on their established racenight ie Wednesdays.
