Walking for Health

Today, I went to get the blood pressure checked and the doctor repeated her advice that the best medicine is walking.  All my life, I have walked but as I grow older, it is even more important.  I hope to stop driving by the age of 65. My reasons being that driving is unfriendly to the neighbourhood and to the environment; that it is easier to adapt to being a nondriver at 65 than at 85 and that I find driving stressful. In a retirement budget, 'shank's mare' is much more economical.

I enjoy walking with a friend best but I am trying to get out and walk alone.  Some years ago, as a starting teacher with a teenage daughter, solitary walks saved my sanity.  I used to go in charity walks which gave my walks a purpose.  Last year, I walked all over Paris and finished my European visit with a guided walk of the last 100 kilometres of the Camino de Santiago de Compostella. I am a walker not a hiker. 
I need strategies to keep going when the weather is grey and rainy or my walking friends are unavailable. My goal is to walk 5 times a week for at least 40 minutes. I hope that this will be a tool for a healthier year.
