>>1659512I live in florida so imagine the lack of elevation makes a difference but for me its 10x easier to cover ground on a bicycle vs on foot. My longest haul on my bike is 42 miles in 4 and a half hours or so but by the end of that I was winded.
I would also mirror what the other anon said, not having a bicycle fit for your height makes things much harder. Bike quality also makes a difference. I went through 2 shitty walmart bikes that were frustratingly heavy and hard to get moving before finding a decent used hybrid online. Another thing that also impacts how hard cycling can be is wind resistance. I was once cycling into pretty heavy gusts and I was making so little distance for the effort applied I almost just started walking
