Driving+Cycling mpg

Driving miles plus cycling miles per gallons of fuel. Include drinks if you buy them instead of tapwater.

I did not keep track of my driving miles or gasoline, since I was more interested in cycling miles. My truck is old and gets poor mileage, but I drive it less than weekly. In driving+cycling mpg I may still get less than some drivers who don't have bikes. People who have both bicycles and motorcycles probably have the highest numbers.

I haven't a clue. I drink filtered water in my water bottles and don't have a car. So it doesn't calculate.

my van uses 11 l/100 km
i think that is somewhere in the neighborhood of 30 mpg
but i think in imperial gallons
if i have to use gallons at all

i dont know how i would calculate a comparable mpg for riding
as i seldom drink gasoline
i prefer slightly diluted ethanol
or in a a pinch
diesel

You consume calories to power your ride. Depending on your weight and some other variables, if you ride reasonably fast, say 18 mph, you might burn 600 cal/hr, so 600 cal/18 miles. Figure out what you pay for that. If you just ate Clif or Power bars, it'd be similar in cost to the gallon of gas to drive 18 miles in a crossover SUV.

A gallon of gasoline contained the equvialent energy to 31,000 calories, so is much much cheaper than any food with respect to energy content.

People who only drive also consume calories.

A lot fewer...perhaps less than 75/hr while driving. You expend energy powering a bicycle, and that energy comes from what you eat. The more you ride the more you need to eat. Light skinny TDF riders eat 5000-6000 calories a day and still lose weight over the course of the race.

Started out fat and are losing weight? That only means you already ate and paid for the energy you're using on the bike.

I guarantee there are plenty of people who don't bike or otherwise exercise who consume as many calories as I do to bike 20 miles a day. I guess you could say they are sequestering carbon, though. By "consume calories" I meant eat, not necessarily burn.

Volkswagen did an ad back in the '70s claiming it was cheaper to drive a Beetle than to walk. Don't remember the details, but they took the cost of gas to power a VW over some distance and compared it to the cost of food to provide energy for a runner to cover the same distance. I forget if it was before the first Arab oil embargo (when gas was 25-30 cents) or after, when it soared to 49.9...

Hey! Perhaps fat people could sell carbon credits!

I had my new truck impounded for 60days so I had to buy bike I bought 21spd mountain bike I like biking now. I even by carbon credits to punish my self for driving my truck I keep track of my km drivin and buy carbon credits at end of the month. I also like being fit now and I'm into motocross so being fit helps with that and I now offset for my race quad to. They need to have vehicles tested for emissions all across Canada.

There's a difference between consuming calories and expending energy. A person who only drives may consume as many or even more calories than a cyclist, but they won't necessarily burn them off like the cyclist does.

Yes. It's like the difference between filling a big gas tank and actually using the gas driving. You pay when you fill it up. If you don't drive, it just stays there, but it's still paid for. If you maintain a constant weight, you'll need to eat more calories if you exercise than if you didn't. The amount being what's expended in exercise and additional for increased basal matabolism. So, exercising has energy costs, and an environmental impact incurred during the production, transportation and storage of the food in which that energy resided.

600 Km is 62 miles, and 11 liters is about 2.9 US Gallons, so the van gets 21 mpg.

I buy one gallon of gasoline and set in the garage. No matter how much I ride my bike, that gasoline never diminishes, save for evaporation of course. Therefore, I calculate that my bicycle gets about infinite mi/gal.

600 km is 372.823 miles. 62 miles is a metric century.

Okay, I'll play.

Doing the math on my truck, at the current cost of fuel, to drive 100km (at my commuting fuel economy) cost me $19.35.

Doing the math on calorie burn for my commute for a guy and bike my weight, I (theoretically) burn 1631 calories for 100km cycling. Convert to cliff bars at 250 calories, at $1.50 each, that works out to $9.79 per 100km of commuting.

Convert that $9.79 back into fuel at the current rate, and it works out 37 miles per gallon, or 7.6 litres / 100km

I own I a full size Silverado for no reason so I buy carbon credits for self punishment. I bought the truck new and it now has 38900 km on it but have since bought 60 000k. Worth of carbon credits and some Fox racing cycing gear cycling shorts and Jersey.
