Do you need to be Healthy
I don’t believe for a minute that you need to be a regular cyclist or athlete to do this, as long as you are not in a rush or on a record breaking attempt.
I've been run over by an articulated lorry and suffer permanent spine damage and nerve damage to the whole of my right side, I've fallen out of a 100 foot tree onto a rock, been trapped by a squashed ankle under a digger in a flooding pond, suffered broken bones all over my body, have more scars than you have had hot dinners :), asthma, hypothyroidism, testosterone replacement therapy and more, but its going to take a lot more than that to stop me from giving this cycle everything I've got. I wasn't even a regular cyclist!
My youngest daughter Chloe calls me The Machine, and no doubt a lot of you are tougher than you think. So much for me keeping this lighthearted :), but trust me when I say that if I can do this, there is a very good chance you can too. If your even thinking about it, you already know it might be possible.
How will I cope with being on the road with traffic every day, alone in so many dangerous places you ask?
To be honest, I don’t know. I feel that if I stay home and not at least attempt to live my dream, I will always regret not at least trying. But one of the biggest reasons for me doing this, is that I have always loved life, loved meeting people and enjoying doing what I want to do.
So, do you have to be healthy to do this? At the very least you need to know that you are likely to live long enough to get at least some distance in, and other than that, your good to go.
Update November 2017
Well, I'm pretty impressed with how well I have done thus far. I have cycled from Cheshire to Portsmouth, St-Malo in France to San Sebastian in Spain, over to Madrid, Madrid to Valencia, and all the way along the coast into Southern France and to Marseille. A total distance of 3300 km's in 80 days. More than 20 of those days were rest days too.
Sure, I suffered pain in my spine and joints, and it was quite hard keeping up with meds, but I did it, and I have a long way still to go.
