Humans are much more energy efficient than cars, so it was less than 3/4 of a gallon (100 kcal/mile * 200 miles = 20,000 calories = 0.7 gallons of gas or about 6 pounds of body fat). He's probably much more efficient than 100 kcal/mile though.

When I was cycling I was joking that the bike is not much greener than the car, because it burns 4 ribeyes/100km or 17 miles/ribeye.

If we consider the average diet bikes are still around 1/3 the emissions of cars per mile. Obviously if you eat only meat that gets worse but I doubt it’s possible to exceed car emissions this way.

Aleksandr's training is public on his Strava: https://www.strava.com/athletes/26934035 Something to remember is that this is his pace _after_ pit stops, so his actual running pace was faster. Also notable is that this course was kind of terrible, with four 90 degree turns and three 180 degree turns each lap for 209 laps. There's little doubt that he could run > 200 miles on a course with fewer turns.

I didn’t know you could get a watch with more than 24 hours of battery life including GPS tracking (COROS APEX Pro). The accuracy is a bit weird though, the elevation chart doesn’t make sense.

I knew the Garmin Enduro could do it, it can apparently do 80h of GPS tracking with solar charging: https://www.dcrainmaker.com/2021/02/garmin-enduro-gps-watch-...

I read somewhere that if you’re not at least mostly vegan, e-bikes actually have lower lifecycle carbon emissions than bikes because you end up burning fewer calories and eating less (assuming you don’t substitute in more exercise).

It’s plausible especially if you use PVs to charge. But what about the costs in producing and disposing of the batteries?

So. Lithium battery powered humans would emit less carbon than regular humans?

They would since we could charge them using PV instead of wasteful bovines.

That seems way too high. A rough ballpark of energy expenditure while running is 1000 kcal per hour. Strava has the activity at 16,751 kcal.

Dang, that would be SO impressive... <1000 calories an hour would mean he is running SUPER efficiently from a body perspective, but of course, with the right hydration, nutrition, and temperature it is all possible to burn less calories.

Whether you walk it or run it, a mile is about 100 calories. So, give or take, ~20,000 calories. Divide by 3500 calories/lb. and he burned five pounds of fat he probably didn't have to spare. But not so fast, he was also consuming calories along the way, and consuming a lot.

So calculating the net burn would be quite difficult. But the gross burn was probably about five pounds/2.25Kg.

How much weight did he lose? It's quite amazing how calorie dense our energy storage mechanisms are.

Someone on Twitter calculated about 55,000 calories burned. Not sure if he had things to consume while running - but 8 - 10 lbs of fat burned in one day is wild to think about.

Not sure if he had things to consume while running

Oh, he had things to consume. I ran 16 miles on hilly terrain on Saturday, and just for that I brought about 500 calories with me (not all consumed, some was "just in case").

It has been said that your liver stores about 2000 calories of glycogen. Divide by ~100 calories/mile, and now you know why marathoners hit "the wall" at about 20 miles if they don't chomp on some calories along the way.

The Apple Watch Ultra is rated for 36 hours so long as cell service isn't enabled.

I've started running and an unexpected challenge is boredom. The running is challenging as is, but doing it for ~1h30m has been, for me, well, tedious. I guess that's a byproduct of always being within arm's reach of a phone.

You need to repeat it many times. Then your mind will grasp the idea: you run marathon, you get endorphins, you feel good. When conditioning kicked in, it wouldn't be such a boring experience.
