Touring on a fixed

I think the edited route you mentioned is ideal, I was having a look at the map this morning and it does seem like the most pleasant and beautiful routes to take to Harwich.

I think I'll have quite a bit of time to spare (the ferry doesn't leave till 23.15) so I think it will be a nice and relaxing little ride with plenty of chances to stop and take pictures.

As the T-Level Challenger backpack is super comfy (thank god for the padding) I think I will be able to do it.

I think I'll be bringing (besides what I'll be wearing on the bike)

• 1 Jersey
  
• 3 pairs of cycling socks
  
• 3 pairs of underwear
  
• lightweight sweater for in the evening
  
• pair of vans
  
• t-shirt
  
• 1 pair of shorts
  
• repair gear: 2 inner tubes, wrench, allen key set, mini-pump, tire levers.
  
  

Then I'll strap a bottle cage to my downtube and with some bananas, nuts and PBJ sandwiches I should be fine..

The only lock I have is a Kryptonite NY Faghedaboutit, which I might bring or I might see if I can borrow a shitty lightweight mini-lock from a friend for the week.

Riding with back pack is doable, but not advisable, sweaty, uncomfortable over a days ride. Bikepack or saddlebag infinitely more suitable. Though you could fit your kit into waterproof bag and strap to saddle, I've just ridden North doing just that?
