Terry Fox ran a marathon a day (more or less) in the 80's while raising money for cancer. He only had one leg !!
Rare and remarkable but it is possible !!
And in 365 days, Amanda Coker rode 86,573.2 miles on a bike. (Actually she used multiple bikes.) That's a 237.1 miles per day average. The only way to compare running and bike riding is to use a given heart rate and time. That will produce pretty equal energy expenditures. Otherwise, biking is much more efficient by a factor of 2 to 4.
