What is the most exercise/activity you have done without food or drink?

I went for a 9 mile hike with only 1600 ft of vertical a couple weeks ago with some non paleo friends and they had to stop and snack every 20-30 minutes. I went the entire time at their slow pace with no food or drink, and felt better than they did afterwards.

S my question is, as a fat-adapted person, what is the most you have done physically without having to refuel or rehydrate?

You can run either way, that's what it means to be an omnivore. This week there's a big long canoe paddle in my area. People forget that for thousands of years this was fueled by fish, clams and blubber.

That for me was the proof. My energy level was consistent whether I ate or not.

About once every week or two, I do a longer fast, and I love pairing it with either a long trail run or a long hike in the mountains. Wake up, sip some coffee and water, then head out the door.

Must be a good feeling to knock out 15 miles without having to worry about food/fuel.

Nice. About 4 hours of intense exercise is around my limit without drinking. I did a loop of four 14ers in Colorado with about 2700 total vertical over 8 miles. I was pretty thirsty afterwards, but not bad, and didn't feel the need to eat, and had stable energy.

Most? Probably mt kitahdin. I regularly do 50 mile bike rides fasted too (coffee helps). I questioned whether fat adaptation was a real thing for awhile but after my own experiences and seeing others who have to carb up/recarb to stave off hunger every 30-60min my doubts have been squashed. Very excited to hear of others experiences.

I ran ten miles. It was a bit of stretch, but I made it. This is big, since I hate running. I just wanted to test my limits.

I also did construction work for around 6 hours. I needed some water, so I did drink some. I felt very focused, however.

I went hiking with a eighty-pound pack on my back in the Blue Ridge Mountains. I think I had to rehydrate after four hours.

I ran a 1/2 marathon after a 14 hour fast and didn't need eat or drink during the run. I had a glass of water about 1/2 hour before the run and didn't feel hungry or thirsty during the event. I was pretty thirsty a few hours later though.

I do my regular workouts semi-fasted. So that's either 45 minutes of lifting, 16x100M @ 15s with 1:30 rest between, 8x200M@32s with 2:00 rest between, 3 miles at 6:30 pace or 5 miles @ 7 pace.

My longest was a 13.5 mile run which took about 85 minutes to complete.

I no longer run marathons but I did run a couple after transitioning to paleo. Before I was fat adapted, I would drink every couple miles and take those 100 calorie sugar Gus every hour or two during long runs. After a month or two of paleo, I did 15 mile runs without food easily and drank water only a couple times during the runs.
