15 hours of front light?
You are setting off while it is still light and it will be light again by 4 am. You need 7-8 hours of front light.
Rear lights, on leaving London you are in a massive peloton which has high visibility, once in the dark and lonely lanes even a small led is highly visible. Lots of bright blinky rear lights only serves to annoy anyone riding behind you.
Clothes, judge it on the day.
Tubes, 3 punctures would be highly unlucky, 5 would suggest you should have put new tyres on before you left. I take two, I needed to use one 3-4 years ago.
Food, bring lots of tasty snacks, find me, feed me.
