yes, over 2 days (Reading, train to Bath, cycling back), couple of years back
you may get bored (we did – look canal, look towpath…. ) but there is usually a nearbyish station (which we took advantage of)
we went on a fishing match day and the number of twunts who blocked the path (about 9ft after the previous blockage) was truly AMAZING (with an F) and they got the hump as we wanted to use the path .. anchors, a real progress killer…………
phone up and confirn and book B&B if stopping over. ie we knocked on the door of a place with vacancies (and were turned down the minute he saw two wet and muddy people), saved by a little old lady whose husband had not long died, bikes locked in garage with all his clothes etc, and she laid a trail of newspaper to the room – lovely old girl God bless..
The Bath half is (IMHO) much nicer scenery, but look at the bridges as you go under, some nice stonework etc.
I’d maybe get the train a bit futher than Reading (Newbury/Hungeford, but as I remember it all pretty straightforward, mainly path, some field, some stiles but we did take OS50 maps with us. Might be worth taking a map as you do need to be on the correct side and somtimes the path goes down both sides (for a while if you see what I mean).
