Dang....6+ miles, every other day?
How long does it take you to do the 6 miles? TIA.
A power walk at :15.40 miles pace or about 1 hour35min total time. Then there is coffee and a scone later that un-does it all. I call that my cool down period.
Walking is a perfect exercise imho. Low impact, inexpensive (shoes are your expense), easy to build up the distance
