I'd just like to introduce my website, which may be of interest to you. In 2011, I cycled around the world and I've created the website to share my experiences with other cyclists. It also has quite a lot of info that may help you to plan a long distance trip. There are loads of photos, info on other adventures I've done, events, a blog about the trip and much more.
I've also written a book about the journey, named "Every Inch of the Way", which is available on Amazon.
Would be great to have you visit my website: www.tombrucecycling.com
If there's any questions about planning a bike tour/choosing gear/budgeting/anything else... that aren't answered on my website that I can help you with, I'd be happy to do so here, just post your question and I'll get back to you.
