The conclusion is that on the whole 6.30 at Heaton is the best time. So all Chillingham Road (Heaton) classes are now at that time. The thursday still has the 30 minute fitness session starting at around 6.10pm.
Monday nights at Newburn are looking good however we have immediately had to change to a 7pm start (which IMO is better) due to a bit of a cock up at there end.
