I used to be a fairly strong long distance cyclist ... but that kind of died off a bit in recent years. This year, 2015, I decided to make an effort to lose weight and get back to cycling long distances again. And also to be able to handle the hills in the area where we live now a little bit better.
So I lost 26 kg (57 lbs).
And we rode two centuries (100 miles in one day) ... plus several 100 km rides, one of which we completed about 45 min faster than we did last year.
And I'm almost scampering up hills now. I attribute that to all the stair climbing I do ... and not hauling 26 km (57 lbs) around with me anymore.
