This is a challenge I have always wanted to undertake at some point in my life. I know of several people who spend weeks travelling on buses with overnight stopovers at hotels, but I would be interested to find out how far one can go from their hometown while still returning the same day, all only using local buses.
For example, it is possible to do Southampton to Swindon and back in the same weekday. An ENCTS pass user could board the 10:10 X7R bus to Salisbury, before changing there onto the 12:25 X5 bus to Swindon, arriving at 14:22. In the opposite direction, one would catch the X5 back to Salisbury at 15:40 before changing onto the X7 towards Southampton at 17:45. Even though that journey only runs as far as Totton, one can use regular Bluestar buses into the city from there on routes 6, 8, 11 or 12.
Obviously, anyone with an ENCTS pass can make all of the above journey for entirely free, but anyone without one or willing to pay could depart Southampton an hour earlier on the 09:10 X7 journey, subsequently arriving in Swindon at 13:22. In fact, it is possible to get there even earlier by taking a more convoluted route from Southampton, since most early Bluestar 1 journeys to Winchester connect with the 08:35 Stagecoach 85 to Andover. This then connects nicely with a 09:20 Activ8 to Tidworth, and despite there being a two hour wait before the next 80 bus to Swindon, it still manages to get you there half an hour before the X5 does (12:52). Even so, this option would likely be more expensive compared to going via Salisbury due to more operators involved.
Is it possible to go even further than that and still return the same day?
