Unsupported I did LEJOG with a Top PEAK 2.8 L RX rack bag with rain cover and AGU bar bag. Took a very small front & rear light in case of bad weather.
I wore one pair of cycling shorts, top, merino wool base layer and socks and 1 pair of gloves.
In rack bag, 1 pair shorts, top, and socks and 1 pair undies, one pair of shorts and one t-shirt. It just squeezed in, just ! Merino wool doesn't need washing as often.
I strapped a pair of sandals, overshoes and waterproof to top of rack pack with a bungee cord.
I carried knee warmers, arm warmers and used those at night if it was cold.
Most evenings I'd eat near to b&b and then I'd sit and watch tv in the room so I wasn't out very much to get cold.
I'd wash clothes every other day, my shorts & t-shirts only twice but I figured I was only in a place one night so I wasn't too bothered as long as I didn't smell.
Did the towel trick which dried things very well !
Bar bag carried my phone with charger and
ASOS Chamios cream (best thing I took, very highly recommended) plus maps, one bebit/credit card and some cash. I took first half the maps with me and posted the second half to a b&b I stopped at in Cheshire
I cut down a tooth brush, took small toothpaste tube and small deoderant and used the b&b soap/shampoo. I grew a bit of a beard for 2 weeks.
I had some energy gels, a buff, cycling cap, two spare tubes, repair kit, one multi tool with chain splitter, spare spokes attached to the bike and tape.
Pump was attached to the bike and had a bit of old tyre, also a few zip ties and small first aid kit. Painkillers, plasters, small pack of wipes.
It is worth remembering that you are in a place for only one night so no-one is too bothered about what you wear. You can always tell them you are on LEJOG, it made for good conversation in pubs.
Try a few rides fully loaded, it makes a huge difference to bike handling/riding.
When booking I checked that the B&B would look after my bike and would eat lunch at cafes where I could see my bike. I did take a small cheap lock but made sure the bar bag went with me at all times.
I replaced tyres, brakes and gearing a month before setting off then let it bed in.
I'd stop at bike shops on the way and borrowed their track pump to keep tyres up to good pressure (tho I only did this twice).
Hope this helps in a small way
