Depends on the hills & what time you start.
I found that, even with showers and lockers, there’s a degree of admin that one inevitably carries. Hence, the rucksack ceased to be a tools, sarnies and bladder functional item. After a week or so I began to ‘understand’ the ‘fit-for-purpose-beauty’ of the otherwise hideous panniers….yes, you will want them….you will ‘lust’ for them….they will save your lumbar spine & wrists.
Unless you’re allowed to work in cycling gear, or you’ve pre-loaded your locker with a weeks-worth of office garb, towel, shower kit, spare undies…socks, food (can get expensive if you ‘eat out’).
Having come across as bit of a ‘party-pooper’, my C2W days were the best ever….hope to be doing it all again soon.
Let us know how you got round things, folks ingenuity never ceases to amaze me.
