Most of us aren't riding 80miles/day all year round. And most of us aren't doing demanding phyiscal jobs between bike rides - anyone reading this is who IS in that category can probably ignore me! - so we mostly have plenty of time at the end of the day to top up any missing calories.mjr wrote: 28 Aug 2025, 10:34pmOnly while you've still enough fat to burn, though?

As for how far you can go on no extra food, no-one can overcome the basics of work being proportional to mass and distance moved, or the need to replace that extra energy expended.
