Congrats on not dying! 20 milers are not for the faint of heart.

WTG on the 20-miler. It's nice that you can do this on a path that supports that distance (bathrooms, food). I wish there was a beer hall on my training routes!
I know what you mean about pre-run fueling. The most I want to put on my stomach is toast. I just hope that that fuel I bring on the run will do it for me.
Thanks! I love this path - it's 10 miles start to finish and has really great spots along the way to stop for bathrooms. Very clean and safe.
Can I ask where it is? You're in MA, right? I get out there frequently--and have a "5 year plan" to move back. So am seriously starting to consider places to live beyond my North Shore roots. Daughter has a house in Somerville, and family are scattered on the NS. Running accessibility is one of my criteria.
Are you eating a single clifblok every 4 miles or a whole package?
I used to do an entire package once every 45 minutes to an hour on long runs. It’s been a long time since I’ve used those and I’m no fueling expert, but I think maybe you’re still under fueling? It might explain why you weren’t feeling great?Just one every 3-4 miles!

Maybe someone like @DopeyBadger can give their input?
Ya. I remember it being a chore to eat them because there were so many individual blocks, but I hated the consistency of different gels. Obviously do what works for you, but figured I’d pipe in so that you can do what you need to to set yourself up for success! Have you tried any other fuel methods?

I'd say fueling could be one piece to the puzzle. It could easily be a myriad of possible explanations. Too many recent races, over reliance on the long run, improper pacing on long runs, not enough fuel during the run, too long of long run, etc. And not all of these have to be applicable to @xjillianpaige experience.
With that being said, the lack of hunger doesn't necessarily rule out a glycogen depletion situation. I think you can not feel hungry and yet your muscles could still be craving fuel themselves. Looks like a single package of cliff bloks contains six pieces. They are 8 grams of carbs per blok. So you are taking in 8 grams of carbs every 3-4 miles in this recent run (or 42-56 min). That's a rate of about 9-11 grams of carbs per hour. I would say that's a pretty low number. The maximum tolerance is about 60 grams per hour for a single source carb and about 90 grams per hour for dual sourced carbs (simple and complex). The package itself recommends 48-96 grams per hour (given their recommendation of consuming 1-2 packages per hour). I personally do about 96 grams carbs per hour. My view on fueling is to find your maximum tolerance so that you are ruling out glycogen depletion as a reason for fading at the end of a marathon. You can still easily fade when fueling appropriately during a marathon, but if you fuel to your maximum, then you know that wasn't the reason for the fade.
Since you have texture issues, would you consider carrying some hydration fuel based source? Like Tailwind. You can even super concentrate it so that you physically have to carry less bulk when running. I've done as much as 1 scoop per oz of water. It does not completely dissolve, but it gets the job done. That becomes 25 grams of carbs per 1 oz liquid. So that's comparable to you eating 3 blocks (or 9-12 miles) of what you're currently doing in a single ounce of liquid. Tastes like a sweet tart. You just have to make sure you drink enough water on course to properly absorb it (1 oz water for every 2 gram carb consumed). It also has a good content of sodium/potassium. You do 5 oz of water and 5 Tailwind scoops (125 grams carbs) and you're looking at the equivalent of 42 bloks or 7 packages.
Alternatively you could carry Maurten 320. It dilutes at 17oz for 80 grams carbs. So more bulk, but less liquid to be consumed over the long haul. Maurten can not be concentrated.
Quick clarification, when you say "over reliance on the long run" do you mean when people skip the maintenance runs during the week and hope that a weekly long run will be enough to get them to the finish line on race day?
I've been running with gatorade - maybe I could up my fuel intake to two gummies + a liquid fuel of some sort? Would that help me get to/get closer to the ideal fuel intake number? Math is not my strong suit (and when I say math I include basic addition, my mind just can't wrap itself around numbers). I'd be down for anything liquid so long as it's not gritty. I only have a single handheld water bottle right now, but I could time it on the course so that I have my bloks around the same time as water spots. I can also mess with my routes so that I pass my car more often on training runs so I don't have to carry as much.
Finally, where do you pick up fuel? I don't think I've seen it in my local grocery store. Is it carried at Whole Foods or Trader Joe's?

If you buy directly from Tailwind, they personalize the bags with your name and a nice note of thanks & encouragement.![]()
Yes and no. There are some training plans that are specifically designed around an over reliance on the long run. The Galloway 3-day per week marathon plan is a classic example. As they tend to be 30-45 min mid-week twice, and then 24-26 miles max on the weekend. This style of training can get you across the finish line, but it is more unlikely to leave you fully prepared for the marathon itself. That's because the training of your body for an endurance race takes more than that singular large training load once every 2-3 weeks. Again, Galloway can work, but more often than not, it's not the best choice. Galloway's expressed goal is to get you to and across the finish line healthy. No more, no less.
So pre-made Gatorade is isotonic. That means it's prepared at 2 grams carbs per 1 oz liquid. So if you have say a 10oz handheld water bottle, then putting in 10oz of Gatorade is going to be 20 grams of carbs (2 grams per oz * 10 oz = 20 grams carbs). You're still likely to fall way short using something that doesn't tolerate concentration as much (although to be fair I have never personally tested a Gatorade powder's ability to concentrate).
I wouldn't necessarily describe Tailwind as gritty, but it's definitely not fully in solution if diluted at 1oz water per 1 scoop (super concentrated). There is still some powder consistency to it. With that being said, you have the ability to play around with the dilution of Tailwind such that you can find the right dilution concentration for you that matches your desired consistency. If you can dilute a single scoop of Tailwind in anything less than 12.5 oz of water and find it tolerable, then you'll get a higher concentration of carbs per oz than you would with pre-made Gatorade. So I suggest experimenting with it to see where your desired concentration ends up. One reason I like to recommend Tailwind is it is super cheap on a per gram carb basis.
It's important to keep in mind, that if you make a Gatorade or Tailwind solution, that you can no longer consider that for absorbing any of the bloks that you consume. Those bloks also need straight water at the same rate (2 grams per 1 oz). So a single blok (8 grams carbs) requires at least 4 oz of water to have been recently consumed in order to absorb it. If you fall short on your water consumption compared to your carb consumption, then your body will start to pull water away from your muscles in order to absorb what you've eaten in your stomach. This tends to lead to feelings of dehydration/cramping.
My suggestion - Try to find your maximal tolerated dilution of Tailwind (it'll allow you to carry more carbs to consume with the least weight). Practice drinking that and consuming your bloks on an upcoming training run that you pass your car multiple times. When you pass the car, take a very short break (under 2 min) and drink some water from a bottle you have stored in there. This will mimic your ability to drink from aid stations in a race. This extra water will enable you to absorb the bloks, and will enable you to dilute (in your stomach) the concentrated Tailwind that you're drinking.
If you can tell me how many liquid oz are in your handheld, and how many scoops of Tailwind you can tolerate in the handheld, then I can do any math for you. With a race lasting 5 hrs, I'd try and aim for at least 200 grams consumed if you can tolerate it. That's still on the low end, but that's far higher than the 45-55 grams you're currently on track for. I consumed 288 grams in my 3 hour race a few weeks back, but I live on the high end and can tolerate most any gels (which tend to be the most bang for the buck in terms of getting in-race carbs).
One other consideration depending on how strong your bladder is, is consuming something within 15 min of pre-race. I drink a 17oz Maurten 320 right before I start running. This gives me 80g carbs before I really even start my run and puts me way ahead. So if you find you can tolerate something like this right before the training run or race starts, then you're that much further ahead for in-race nutrition. Anything consumed within 15 min of starting the run can be considered in-race nutrition. But something like a breakfast PB bagel 2 hours before the race is a good idea, but doesn't help towards this in-race nutrition value.
