Badass Will Gadd says your job as an athlete is simple: keep moving. Vivian, who is maybe somewhere between 60 and 90 (a gentleman never asks), tells me she needs a hip replacement so she’s making sure she’s “good and ready” for it. “I used to go to the gym and run and, well (shrug) now this is just what it is”. We talk about the trail, getting out side, staying active and sharp and witty. I can tell she’s a tough nut and is none too sure of me, but we ride bikes and she gets it. Relentless forward progress.
