Jeremy: Today's ride is a follow-up on last week's video, where I got myself into a fully ketogenic
state. I went out and I did some big tests on some local climbs for a video called High Carb
vs. Keto. We went through all the results of what happened and what went good and bad. Today,
I'm following up on that test with a 100-mile ride, again, in ketosis, to try and find out if
I can do it on practically zero carbohydrates. Now, I need to say this to you all.

some bacon that I made up last night, and we're going to throw some spinach on it. We
could probably throw some cheese on top of that, and then we're going to get this ride started.
Good morning. It's just a hair after 7:30. Got up about an hour ago.
Checked my ketone levels, 0.4, which is about what I'm usually at in the mornings,
and then I rise throughout the day. A nice cool 90-ish plus miles on here for today.
I'll be very excited if I do complete that. We're in a big field looking over beautiful
Mount Tom as we make our way north to head out on this super long low-carbohydrate
adventure that we're about to take ourselves on. We're going to be going north all the way,
not quite to the New Hampshire-Vermont border, but just before it. Then, we're going to be making our
way back down. The route I planned was fairly flat, so I have some chance of making it through
this super long excursion. I've planned for 100, but I think once we get towards 85-90, we'll be
back in this area in case the detonation is quite large. Haven't ridden 100 miles at all lately, so
riding 100 miles on no carbohydrates is going to be a very interesting experience to say the least.
All right. We're down in downtown in Easthampton, Massachusetts. As we make our way to the bike
path, we'll pick that up and then we're going to hit Northampton and then go up the
river and make our way north. Super pretty morning out. I'm already sweating. People are
very kind this morning. Got a couple of people just letting
me go through. [music]
All right. We're out of Northampton. It's a beautiful downtown area. We're just making our
way north now along the Connecticut River. Super pretty time of the year here. Hot, but really,
really pretty. Come over this hill, I'll show you guys. We've had to do some stops, but
heart rate is 130 about and I've done about 190 watts average. I've been going harder,
but I've had so many stops and zeroes that that's changing. We're about 12 miles in, making our way.
We're here. This is a very historic and famous little local spot in the area. This
is an American sycamore tree called The Buttonball behind me. It is apparently 25
feet around. 140 feet is its spread, and it's 113 feet tall. Some estimate that the tree is 400
years old. That's old. Think about it. That's the oldest tree I've ever seen.
Just made it to downtown Sunderland, making our way to the Bookmill, where we can
see how we're doing, check in, refuel, and take in some pretty views.
[music] Jeremy: Two coffees. Can I have one
iced? Do you want it iced or do you want it-- Male Speaker: Yes, please.
Jeremy: Can we have two iced coffees? Male Speaker: Yes, sounds good. Anything in them?
Jeremy: Great question. Male Speaker: I'm good.
Jeremy: I'll just take some cream. Just checking the ketones just
to see where we're at, to see what we've got, give you guys some intel.
Okay, so we're up here in Montague at the Bookmill. It's got the beautiful waterfall.
We've made it so far 28 miles. I'm keeping almost 20 miles per hour average or just
under. I'm riding now. I'm at 0.7 millimolar. They say when you're working out and you're
doing ketosis, that when you're working out, your ketone levels tend to drop, so 0.7
is what I would expect. I'm as sure as I continue to sit here, it would go up, but I definitely
haven't eaten anything yet. I may have a snack. So far, I feel fine. I'm averaging 212 watts,
average heart rate of 126, and we haven't climbed very much. The temperature, really hot,
93 degrees, which is obviously well over 33, 34 degrees Celsius, so we're definitely up there.
They say that you burn more when you're in ketosis from the sun. I'm joking. They don't say that, but
I am putting on some sunscreen. This is a general PSA, we always have to put our sunscreen on.
We have to stay healthy. We have people that love us, care for us, so wear your sunscreen. That's
all. That's all for right now. [music]
Now, a question that I know you're all going to be asking is, "What are you eating and drinking
on this ride?" In my bottles, I'm using Enervit Salt Caps in practically all of them, just to
make sure that I'm keeping up with my electrolyte demands for such a hot day. For food, I'm eating
fat. Of course, it's the primary fuel of the day, is mainly salted cashews is a big one, and I also
have some weird keto bread sandwiches that I made with peanut butter and bacon. My goal is to
consume around 2,000 calories on today's ride. I have to say, I didn't even know this one was
dirt, but I'm pleasantly surprised and happy. It's beautiful out here. Got the river off to the left.
Got the trees overhead with the shade, just lights poking through like a disco ball. So sick.
All right. We're at our northernmost point on today's journey. We're at about 42 in change
miles, 2 hours and 11 minutes, over 1,700 kilojoules, 98 degrees Fahrenheit, so it's super,
super hot. I feel really good on the bike. My power output's actually gone up to 214 watts.
My average heart rate, 130. Feel a little crampy, I'm not going to lie, but given the heat and stuff
like that, it is hard to get the electrolytes in. I feel pretty good overall, though. My power
output obviously going up. My ketone level is continuing to rise. So far, though, so good.
Super pretty up here.
Holy crap. It's really hot. I'm not going to be able to do 100, not because of the
ketogenic thing, just because of the heat. Just because of the heat. I love you guys,
but it's not safe out here. It's the hottest I've ever felt. It's like the Sahara Desert.
We're going to start making our way back down. The ride is still going to be close to 5 hours.
I think we'll all get the point, and I'll be able to actually stay alive. [laughs]
We couldn't miss an opportunity to hit some single track.
[music]
You guys know that I couldn't do a ride like this and not hit a big gravel section.
I had to do it. [music]
All right. We're here at Baker's, a local spot. Definitely the energy level is
not super high. Going down, I'm still rolling about 210 watts average, which has been where
I'm at. My heart rate's about 132. We've done about 65 miles, 2,700 kilojoules or so of work.
I'm feeling it, though. The heat is insane today, and this is a crazy day to be doing something like
this. I would have bonked hours ago. If I had been out here and I hadn't been in this state
that I'm in, I would have absolutely been on the side of the road, needing someone to pick me up.
I haven't eaten nearly enough calories to justify this type of energy expenditure,
but the ketones are protecting me. They're continuing to turn out and I'm continuing
to be able to do the work, which is so surprising. This is definitely one of the weirdest things that
I've ever done in my entire life, I can say that factually. This is insane to me. I would not have
personally expected this, but I think that's what makes this so interesting and so weird and wild.
Just did a check here on the meter. Ended up at 1.1, is my level of ketones right now.
I know we're in. I knew we were in because I haven't eaten anything and I've done 3,000
kilojoules of work. I don't know. Who knows what I'm doing? Who knows what we're doing?
We're doing it. Let's get out of here.
All right. Well, we're still climbing. 65, almost 66 miles. It's been a long day.
Feeling all right though. I'm still cruising. All right. We're back here at the vineyard.
84 miles, 3,400 kilojoules, four and a half hours. Average heart rate was 134, 206 watts
average. I only lost two watts between Baker's and here. I have a lot of things to conclude with.
I'm calling this a proper 90 plus because I rode here. I'm going to ride back to my place.
We did a lot of takes back and forth. We've been out here about 10 hours. It's been a long day.
The heat is insane and I'm not willing to push it anymore. With the heat, I've lost a lot of
electrolyte and salt. This is just kind of where I'm at and I'd be at, regardless of whatever state
of nutrition I'm in. I'm going back to my place. We'll do a conclusion there.
If you guys can't tell, I'm struggling with this one. I predicted things were going to go a certain
way and the outcomes that I thought, they just didn't come true. I had initially titled this ride
the Bach ride because of what I thought was going to happen. Now,
if you think back to last week's video, where I was up and down getting into ketosis, I was all
over the place and I didn't know what was going to happen. On today's ride portion of the video,
I have to say, this was one of the craziest days that I've ever experienced on the bike. I was
certain that I was going to bonk catastrophically and need to be driven home or even worse. I was
actually anxious when we were getting going, given the heat, the duration and what I was attempting
to do, but literally nothing went wrong. It blew my mind. It still has. I'm trying to get my head
around what's happened. I don't know. I was able to churn out the watts. My heart rate didn't go
crazy. I didn't get heatstroke. I did do the ride at a low intensity. I didn't give it 100%
of every single climb as hard as I can. I did have periods where I got my heart rate close
to 170 and I went super hard. Last week in that video, I also went all out to test that there.
For me, I've always had trouble with low blood sugar. In fact, my entire road racing career I
think was hampered by the fact that I was a sugar burner and that I never could do six,
seven-hour races. I'd always be the first guy to be like, "Yes, I'm out of here. I can't do it."
I wanted to see if I could be more metabolically flexible as a test for myself, to push myself.
Honestly, this was not easy for me, as I would consider myself a carb guy my entire life. I
just wanted to see what this was all about. I'm intrigued still by what's happened, mainly because
it's completely contrary to what I was taught growing up and what I still believe in today.
Diet is so personal, and what works for me will not necessarily work for you. You may feel amazing
as a vegetarian or a vegan, gluten-free. I'm not here to say what will or won't work for you. I'm
not here to say that I'm going to do this kind of diet or that I subscribe
to any kind of diet forever, and you should either. It's not like that. I'm
not promoting that. I've learned so much. That's something that I love. I love being a student.
I love to keep pushing myself and learning new things. From this experience, I learned a ton.
Next week will be the last. It'll be the third video in this series. I'm going to get my blood
tested. I'm going to see what's going inside with my body. I've got several interviews lined up.
I'm going to be talking to people on both sides of the table. Experts, athletes, all types of
people to be able to bring you guys the research that they've been able to do and hopefully get
us some more conclusions and takeaways. I want to thank you guys all so much for
watching. Leave us a comment down below. Let us know what style of eating works best for you.
We'll see you guys next time. [00:14:54] [END OF AUDIO]
