Well I forgot:
Winter boots
Bike Stand
Clock
Calender
Bits of carpet to put on the floor to put bikes on so the bikes don’t ruin the carpet that doesn’t actually belong to me
Short sleeved cycling tops (I brought 1 mtb one, and 1 road one.. useless)
I did remember
Bikes x4
Tools
Shoes
Pump
Water bottles
Overshoes, winter gear, etc.
Camelbak + bladder
Helmets + armour
Sunglasses
Gloves
Maps
Spares etc. inner tubes, pads, bits of cables, sealant, etc.
As a last thought chucked in some food and a pen in case I need to write something down in one of those lecture thingys.
Where you off to?
