Okay what about cycling for 14 miles there and back, in the day and night in London? Can anyone give me tips for this part other than high vis clothing and lights?
You'd be better off starting a thread in "commuting" you'll get plenty of help and suggestions.
but for starters (and this is all mostly in the guide)
communicate with drivers .
Observation, use plenty of rear obs in particular (some say every 20 seconds)
Clear and predictable moves.
Take a strong and clear position and thank those you hold up in doing so (communication really)
Eat bannanas
Use wet lube
Wear glasses
Carry or wear overshoes
