Would that be a difficult bike ride, across fields? How long would that journey take? Sorry about all the questions!!
By bike, something between 30-45minutes I'd say.
Difficult?
I guess it depends who you ask, people who want to persuade you that Jeremy was innocent would no doubt tell you that it was an impossible journey, in pitch blackness with a deadly crumbling seawall between you and certain death.
Those who want to persuade you that Jeremy is guilty might tell you that it was an easy journey, in fact it's so easy that you may as well leave your car at home and stay off the main roads all the time, this is in fact a short cut.
The reality is probably somewhere between the two.
Yes it was night time and dark, but there was moonlight, whether enough to make the journey or not, who knows? I'd say it would add to the journey time but not make it impossible.
The majority of the journey is by farm tracks several metres wide, potentially just about 800metres is along the seawall which isn't and wasn't anywhere near as treacherous as is being suggested, Think of it as a mound with a track on top of it rather than a wall, plus there was and is a grassed track at the bottom of the mound for a good length of it (that the farm vehicles use(d)). Right now some cheeky bugger has put a caravan on one corner of the seawall which people are using as a base for going kyaking.
Also the police walked several routes (on advice from Robert Boutflour), they clearly considered the journey possible and in turn the prosecution clearly persuaded the jury that the journey was possible.
I'm not sure what else I can tell you about it.
