Having that amount of time to take photos and you either took it easy- or you are a lot fitter than I am. But you can't take a century ride easy so the training done in the last year has paid off. Just keep it up but stop these 100 mile rides- You'r putting us wimps to shame.
Had a bypass in 99 and 12 weeks later did a tough 40 miler. Took another 4 years before I did a century ride though.
