Hello OceanMan.
That's nice to see some more French going to Cranfield.
I was one of them 3 year ago (I am getting hold !!) and am living in UK now.
At the time I had no car (and if you are wondering about taking your car or not in September, take it. There is nothing to do in Cranfield, except studying or playing counter-strike, I was very good by the end) so I was not doing much freediving. Anyway, I have just started last year....
So I don't know if people train there, but I doubt so
However, you are not far from London, where you could do some pool training (you should have a look here
http://www.britishfreediving.org/ to have the list of the clubs)
Otherwise, you are very welcome to come and train with me and a friend in Leamington Spa (about 50 minutes North of Cranfield) we are going every Wednesday evening. We are trying to get access to another pool for more training.
About depth freediving, the best would be Chepstow, in a lake. Have a look here

What are you going to do in Cranfield? an MSC? which one?
PM me for more info about life in Cranfield or other....
