I've not been to the velodrome for a while too, used to go twice a week as well as have a ride when I took kids from the school I teach in. Never bothered with accreditation, just did the Monday and Thursday tasters as we had a good group who weren't too fast / weren't averse to putting the hammer down now and again. First started taking schoolkids down there in 2004 / 2005, we used to get there early and watch the GB squad sit 3mm from the rear end of the motorbike and whistle round at 60mph+ The GB squad were amongst the frielndliest down to earth bunch you could wish to meet - Hoy, Mclean etc, used to come and chat to the kids, sign waterbottles etc. Remember watching a young Cav and the coach (Andrea - think she used to be a bloke!) said, "keep an eye on that kid, he's special" She (He!) wasn't wrong.
