Where are good training grounds/routes for cross that people are using? I've just been doing laps of my local park but some more technical trails stuff would be ace (I'm south east London based.)
Did you do the Bethlem round of the Summer Series? I regularly ride that and some parts of it are fairly technical.
As for Kent, there are loads of bridleways accessible from south east London. Lots around Farleigh, a long one from Keston to Sheepbarn Lane, more around High Elms.
