Thetford is pretty flat but what gear ratio is a safe bet if it's muddy, etc? I have 40x17 on now which is ok for me pushing the fat tyres on road but knobbies in dirt? No idea. Should I fit a 36T up front? 32T?

Oh, this is for 3hr race, not pootling around. Although I may just be pootling around if it all goes wrong :)

26" wheels, I take it?

32x17 would have you spinning like mad at Thetford, even in the Winter slop. You could ride a 36x17 easily there. For a 3hr race, maybe a 38 would be better

So basically leave it as is? That's my kind of mechanicing.

Yeah, 26. I'll blame any slowness on being slightly over geared, not a total lack of skill.
