JakesDad - Thanks for that, I thought touring was a little different to relatively small distance rides so I didn't think to look in there but I shall do now, thanks!
Arch - Thank you that is incredibly informative and covers most points i've been thinking about. All the equipment you mentioned I will be taking I think, maybe a few more bits + bobs. And as for where we're going, it'll be from Luton to Epping Forest.
We did have planned to go to Southend from Luton in 4 days, but being the worried parents I have, they thought it was ridiculous so I must prove to them I can do it before they'll let me unfortunately!!
RedBike - thank you for that, would you reccommend I carry on my bike or via a rucksack?
Snorri - Thanks! I do hope it gets addictive, the thought of doing it is pretty impressing I just cant wait to get out there and do it!
