Thankyou for your enquiry regarding gymnastics. We run our adult gymnastics classes on a Monday evening 8pm-9pm and a Wednesday evening 7pm-9pm. We have other people that attend that are interested in Parkour and come along for the purpose of gymnastics helping that. The cost of the monday class is £5 and the cost of the Wednesday class is £9. You can pay as and when you come.
