I'd call it an "adventure" but to me an adventure is when things go badly wrong. You had a very large vision to concieve of, plan and then execute that epic journey.
Congratulations Andrew. When you're my age (67) you'll look back on that time with not only pride of accomplishment but great memories. I've done long Canadian wilderness canoe trips and the 2 day, 100 mile Canadian Ski Marathon and I look back on all of them with fondness. Long preparation is the key to success in efforts like these. Your preparation must have been very well done.
P.S. If you share with us the details of your preparations I think it will be invaluable information and will inspire us to do our own big journeys.
