I have always been into running and would usually go a distance of 2-5 miles with a back pack or heavy vest on (becoming very tired). I recently got back from some advanced military school and found my self running about 8 miles with a back pack on. I was never once tired either. I cant wait to go further tomorrow.
My question is how safe is it for me to run with a back pack/vest on? and also what type of sneakers would you recommend for safety? (I run on pavement)
