I wasn’t thinking.of taking much. T shirt, shorts, boxers, shower gel and toothbrush/paste and only flip flops for the evening. Maybe a jumper for a cooler evening.
You can probably halve that list. Wear cycling shoes you can walk/relax in. The b&b will probably provide soap, wear your baggy riding shorts in the evening. Down jackets pack much smaller and weigh a fraction of a jumper.
“Maybe” is the enemy of lightweight packing.
Interesting to see others are recommending handlebar bags, do they not affect handling? Is there any benefit to them over frame or saddle bags?
I think they make the least impact on handling even when heavy as you’re effectively holding the weight in your hands. It just takes a bit more effort to lift sometimes.
But if your entire packing weighs more than a kilo then Id suggest you’ve packed too much for what you intend.
