i really would not bike up either of them roads for that long, the A5 gose dual carriageway past milton keynes and is very busy all day long.they really are not ideal roads to bike on,with a lot of fast moving traffic. best of luck if you go for it
i`m with you on that one,find a bridle path and canal tow paths and play it safe.
what am i thinking by starting to ride again!!!!!!!
