OK - so I am proud of this. The last 3 years. Travelling Europe and riding the Cols - 200 in total. I started wanting to manage Cent Cols but they are addictive. Any advice would be to do this whilst you are young enough to enjoy it. The whole experience, from the endorphins to the scenery, provides memories that will last a lifetime. I also lost circa 30kg over the time but became fitter and fitter as time went on. Long rides as often as you can if looking for weight loss.
