to ask if anyone has a LONG walking commute every day

I loved my walk/cycle to and from work. It was around 40mins stick a podcast or music on bliss.

What's your route like? Anything likely to be shut off if it floods?
I opted to do a further route to avoid road walking and busy areas where I wouldn't be able to switch off needing to be alert.

It's weather that's the ball ache. Having to take extra rain protection and the like. Shoes need to be good and comfy. I actually got some reoccurring foot pain from wearing the wrong shoes so they are a must.

It's definitely do able but there is days you don't want to feeling under the weather/heavy period and do have to factor in the extra Time. Maybe give it a 2 week trial?

When I was working (I retired 2yrs ago) my commute was 45min walk, 1hr train, 10min walk. I WFH some of the time but they were beginning to calling us back into the office more & more.
The walking was fine much of the time, even in poor weather but it was the heat that did it for me (like a PP I had quite a hill to climb as I got closer to home) and it was on one of these walks that I decided the time was right to go.

I used to do about 40 mins pre DC. I didn't have to do it every day, as there were bus/bike/cycle options so I could change my mind and get the bus home. I liked the time to listen to podcasts etc. I definitely used to do it more often in summer though as it was just an option not a necessity!

I walk quite a bit as part of my commute - invest in a good lightweight foldable mac in a colour that you're happy wearing, and take it with you everyday. I always have over 12k steps by the end of the working day, without particularly trying.

Mine is 50 mins each way. I enjoy it. It doesn't feel long or onerous. The worst bit is walking back home, I live at the top of a 20% hill and that's right at the end.

My husband has done this for around a year. Works well for him - other than when the weather is fine in the morning but torrential in the evening!
