Hey Jen,
I hope I am not overstepping here BUT (ha ha!)!
I am a physical activity coach (though that is not the word I use to describe myself normally). I read your post and saw something that I thought I could help you get over. You said that my 28 miles would take you over 9 hours and you aren't ready to commit to that much exercise yet!
Well forget it!!! Don't commit to 9 hours, or 6 hours or any hours this week!
Just commit to 10 minutes today!
Let tomorrow come as it may, forget it! Make your commitment to NOW. It's not as silly as it sounds. You might have to a little bit of preparation first but it does get easier. So if part of your problem with walking is having to dig out the comfy shoes then keep them by the front door! Then the very moment you think you have 10 minutes to spare you can put them on and go!
I know this sounds simple, and it is. But you seem to be focusing on the end result, 9 hours of walking. And that is a very large goal and an almost impossible lump to swallow in one go. It took me 6 months to get there! Set yourself little goals, like 10 minutes walking today, with a couple more minutes added on by the end of the month. It will soon build up! I think WW etc do this too. Rather than saying 'Stef, you need to lose 4 stone (56lbs)', they say 'Stef, your first goal is to lose 7lbs'. This makes it a more accessible target.
I know this is a bit much, you don't even know me. But if you want to e-mail me feel free. My job is to help people increase their daily activity levels to achieve improved health. I don't focus on weight loss, or looking thin, but on feeling fit and well. The weight loss comes as it may and is very welcome, but it is not a primary goal for my customers (all of whom are very overweight, e.g. 400lbs+).
So get in touch if you want some personal one-to-one, Stef
