Yeah found that the trainer lady was particularly harsh to us today. We had no idea that there was a kids session on and she demanded we leave immediately with no warning. We then happily packed the court away and hung out on the picnic benches only to be told we cannot wait there and we must leave the inner circle of the velodrome. I didn't really get it. So we left and came back at 4 when the session had finished. Think the trainer dealt with the whole situation badly and made us feel not welcome and a nuisance, not really what I would expect from a sports facility like herne hill.
