After a beautifully hot shower, I surfed the interwebs and found this.
It. Made. My. Day.
Note his rather upright riding position on a drop-bar bike. He's entitled at his age to set his bars as high as he likes.
Reading the article over at otherwise-increasingly irrelevant Velo News/Velo, I was surprised to find that, with few exceptions, Marchand listens to his doctors. He carefully keeps his pulse at 110 or below when riding -- his resting pulse must be in the 40's! -- and now limits his longest rides to no more than 100km (62.5 mi). He's apparently in excellent shape for a fellow his age. His feat persuaded the UCI to create a new age category for the mile record (100+). And his story made me smile.
