@Eddie I have found it to be good so far, the staff are very friendly and the races have been turned around quite quickly. I'm sure you've read the comments on the TDR forums about it being endurance favoured which is true on the Saturday, as a sprint rider you get 10mins of qualifying and 1 race then that your day over unless you do multiple classes. Sunday though is purely sprint with 2-3 hours between races which sounds a lot but is most welcome. If you have any questions feel free to send me some messages on Facebook, or if you decide to do some rounds you're welcome to park up next to us for some (non homo) company
I have found my riding come on a lot just from racing so really recommend it if you want to get quicker. Just be prepared that it will cost a lot, I budget around 1k a meeting (without crashes) but thats coming from Devon each time.
