Riding a recumbent trike on tracks like this brings added interest/danger:
1.you are too wide to pass any vehicle,
2. your face is at the level of brambles and nettles,
3. you cannot avoid riding on the central section , the only choices are whether it is a front wheel on the central section meaning the whole machine is on a slight tilt or the rear wheel rides down the centre with possible reduced traction.
The most interesting track attempted so far like this was Ebbor Gorge near Wells. Single track lane with pot holes and a mixture of loose gravel and grass down the centre. Luckily I didn't meet any other vehicle. I had hoped that the descent would be fun, it turned out to be exciting as the trike frequently fishtailed on the loose surface
