I'm planning on attempting the tube challenge next week (not for the record), so I would need a travelcard covering zones 1-9. I am aware of the 'trick' of setting the origin station within Zones 7-9 however I hold a 16-17 saver which is not valid on travelcards with the origin station inside the zones. So what's the cheapest option? Thanks in advance.
