Hi,
unfortunately there are even no offroad tracks in that area. the nearest option would be my local club track, but it's ~ 100km to go. Here's the link:

There's no race in that period of time, but you could always check in for a chat or practice.
Here's a google maps application showing all offroad tracks around:
