    Cycling adds between 250-1000 extra calories per hour, though it varies by speed and weight.

    My historicals show I burn ~500/hour on my longtail with my kid on the commute, and an hour of commuting time would be 25 kms travelled. 500 cal is about 500 grams of beans, so 500g of beans per/100 km. For comparison the car I have is 7L/100km.

    I can buy 1kg of beans for 5$, and 1L of gas for $1.70. So by bike is $2.50/100km. By car is $11.9/100km. If I fueled solely on sirloin steak (2cal/g) that would be $13/100km.

    Now, I happen to fucking love beans and cooking them many ways. But these costs are also ONLY fuel, ignoring all the other costs and benifits associated with both methods of transportation.

    For example, I always travel 25kph by bike. In the city the trip average speed by gar is 35kph, so not a big difference. If I’m travelling outside the city, the trip average will be closer of 90 or 100kph by car, and still 25kph by bike.

    My bike also costs $0 in insurance and very little in maintenance or repairs. I also get to scrap as much cardio time from my workouts as I put into cycling; either giving me more time in the day, or letting me focus on another activity.

      Before you posted I had done similar calculations based on my former commute. Its only theoretical as I’m FT WHF now, but my commute was ~45mi per day round trip and at my weight, and intensity the calculator I found estimated a shocking 2500-3000 calories. That’s 125-150% of my regular caloric intake just for the commute.

      Doubling my food costs would far outstrip my gas costs for the commute.

        3000 calories additional for 72km? I think there is an error woth your calculator, or it may include BMR in the estimate.

        Tour de france riders consude about 5000 calories per stage. Though they are obviously optimized for it.
