me and my mrs started walking last year, on days we didnt fancy a bike ride.
started with a very slow couple of miles, as i was/am quite immobile in my legs, due to a hip replacement and a fused ankle.
we kept at it, slowly increasing distance and time. walking on holiday for a day whilst on bike tours, walking on the beach in northumberland is my fave.
we are now up to walks of around 10-12 miles in length on various types of surface and terrain.
we are currently walking a 60 mile loop local to us, in 10 miles sections.
one thing i do know, walking 10 mile is far tougher on my body than riding a steady 100 miler on the bike.
the days following a long walk are pretty painful on my stiff joints……. but i love the different exercise and so we will keep at it.
