That’s 1440 slices of toast per day. Using random numbers from google, that’s 110k Calories worth of plain white bread. Assuming 6 people putting in the work, that’s a bit over 18k per cyclist for 24 hours cycled, who each would require about 12k Calories for the work put in.

However, this is just to toast the bread, not to make the bread. I’m being a little dumb and taking this hypothetical a bit too far.

Though apparently a horse can travel just 20-30 miles per day, while an average cyclist could do 60+.

A horse on a suitably adapted “bicycle” could easily travel 60+ miles:

During that eight-hour day it was estimated that the horses could propel Impulsoria eight times over a thirty-mile route.[1]

A cyclist without their bicycle would be closer to 20-30.
