Hi folks,
I decided to start a new topic on this so it wouldn't get lost in my other marathon thread. I am signed up to run my first marathon on October 2 of this year. I've done a lot of running, but no long running. I am looking for info on where to start with food & drink options in getting ready for this. My specific questions are: 1. How do you carry it? 2. What to look for in gels/snacks/other foods 3. How often will I need to eat or drink something during a long run? 4. What should I consider eating or drinking immediately before and after? 5. What should I consider eating or drinking the day/night before a long run? I normally stick to 6 miles or less, so have never needed to think about it. Thanks in advance for any advice on this. |

I leaned to not count on the event organizers to set out water spots as they claim.

You should probably run a couple of marathon distances before deciding, when you hit that wall you won't want to be carrying an ounce of extra weight.

View Quote First, this should be something that you work out in training, during your long runs. Don't wait until race day. Second, what is a realistic marathon time for you? How much do you weigh? That will help set consumption rate. I wouldn't get too wrapped up in pre/post workout nutrition concerns. Studies show that muscle glycogen is the same regardless of whether you do a post-workout carb reload or just eat normally unless your next workout is within 12 hours of your previous workout. If you aren't doing two-a-days, just eat normally. Before a long run, you might find eating some simple carbs helps and eliminates the need to carry gels or sports drink. Personal preference matters, but gels, sports bars, fig newtons, or bananas are standbys. Test this in training. Stay hydrated, which means drink to thirst. No need to force-chug fluids. During exercise, your body absorbs moderate carb containing fluids a little faster than plain water - Gatorade has about the right carb content per volume. Test this in training to find what works for you. For me, water works well out to at least an hour, maybe 90 minutes depending on intensity. Higher intensity means maybe some calories. Much more than 90 minutes and I am looking for maybe 100 calories per full hour run, so 90 minutes = 100 cal, 2h15m = 200 calories. This can be gels or sports drink. Experiment with this during your long training runs. You don't have to consume equal amounts of liquid that you sweat off. You just have to slow the rate of dehydration. The fastest runners (those who win or place highly) also tend to be the most dehydrated. Again, what is a realistic time you expect to be on the course. For a large marathon, it's probably safe to count on fluids, but maybe not calories, especially if you aren't in the first third to half of runners. Gels are compact and easily digestible, though some prefer gummies. Those calorie numbers were for a 190lb man. Scale up or down for your size and experiment during training. Bottom line, for extended duration events, training includes figuring out nutrition as much as it does pacing and fitness. |

I am definitely not planning to wait until race day to figure this out. The race is 6 months out, and I plan to start on my "official" 16-week training program in mid-June. I think that a sub-4:30 finish is doable, but I'll be ready to adjust that expectation after I get deeper into it. I typically run about 8-minute miles now, and an all-out 1-mile would be in the 6:30 neighborhood. Based on that I am thinking that I can maintain under a 10-minute mile average. I'll find out relatively soon if that's realistic. I am 5'10" and currently 170#, but I plan on getting down to 160 or less for this. |

Don’t overthink things food/drinkwise.
Pre- and during race: I never worried to much about anything other than w*a*t*e*r (i.e. staying hydrated). Unless there is something wrong with you, water is all you will need. Marathons are run on fat and a normal person has plenty of fat/fuel for a marathon…which brings up the need for long training runs: you have to train your body to utilize and run on fat. The place to overthink things is in training. Like anything else in life: determine plan, train to plan, execute plan. There is no substitute for long miles in training. Granted, it’s hard to run the equivalent of a marathon in training, but you should have a lot of 20+-milers under your belt before your first real mar. Marathon joke: it’s a 20-mile warmup followed by a 10k. Old rule of thumb: a moderately trained runner go run three times his/her average daily training distance before “hitting the wall”. Run those numbers backwards and you have to run about 65 miles per week with an average of around 9 miles per day to run a marathon “comfortably”. Halves are decent training runs but they are just that: half as far as the real run and no indication of how you will do when you double the distance. Final recommendation as some have already said: determine (through long training runs) what pace (i.e. well below your lactate threshold which should be determined during training) you can maintain for 26.2 miles…then stay on pace. It’s easy to be excited and go out (too) fast; doing so will really hurt you on the back end. I always tried to run negative splits: go out slow and speed up by a few seconds per mile as I went. Good luck. Marathoning is a fun endeavor that few people ever even attempt and once completed you will always look back on as (a) significant accomplishment(s). |

"The wall" is really a pacing problem. People run faster than their fitness, burn more glycogen than they can restore, and bonk.
Otherwise people couldn't run ultras or Ironmans. Agree that marathon are run mainly on fat. Disagree that novices looking at 4h30m marathon times need to run 3x 20 mile runs. That is inviting injury. Lots of weekly miles. Typical weekly long run no more than 25-30% of weekly total and run as many days/week as possible. At least 5 and 6 or 7 is better for most. |

Quoted: You should probably run a couple of marathon distances before deciding, when you hit that wall you won't want to be carrying an ounce of extra weight. View Quote Do NOT do this. Edit: for storing water I have a hand held soft water flask from ultimate direction. I think it’s called a clutch now. It has a bottle, inside a holder that has a strap that goes around you hand. I’ve done belts and vests. Belts work as long as you adjust them properly, and the lessons I learned were from poorly adjusted belts. Gels I shove in my hand held or in pockets. You’ll want to practice using them for race day. Pacing is important. Hitting the wall sucks. You don’t need to run 75 miles to comfortably run a marathon. Trust me. See if you can find a half marathon race. If you can then race it and double the time then add 10 minutes to get an idea of where you’re are for marathon pace. If you can do a 10k then do that. The internet is filled with marathon predictors. Look at them if you want but they might not be accurate, or consistent. |

Quoted: Hi folks, I decided to start a new topic on this so it wouldn't get lost in my other marathon thread. I am signed up to run my first marathon on October 2 of this year. I've done a lot of running, but no long running. I am looking for info on where to start with food & drink options in getting ready for this. My specific questions are: 1. How do you carry it? Some running shorts have specific pockets built in to the waist for carrying gels and other such nutritional items. I like the Patagonia Strider Pro shorts, though the Brooks Sherpa shorts are another similar option. Path projects also has some very nice shorts with lots of pockets. Another option is something like a Naked Running band (sizing is very important on these, defer this if you're planning on slimming down) or a Nathan Pinnacle belt 2. What to look for in gels/snacks/other foods. Easily digestible, preferably ones that you do not have to take with water - you don't necessarily want to force yourself to only take a gel or other running fuel based around water stops. Science In Sport gels are a bit larger than most, but have a thinner texture and don't have to be taken with water. Personally, I use the fancier Beta Fuel version of their gels and haven't had any issues with them. Maurten is another of the newer gel types that don't necessarily have to be taken with water, but they're a bit pricier (same with the Beta Fuel I mention previously). Stopping by a dedicated running shop and picking up a variety of gels with which you can experiment is a good practice. 3. How often will I need to eat or drink something during a long run? With the exception of long runs that also have some quality in them (read: typically increasing/progressive effort through the final several miles or dedicated marathon-effort blocks) I like doing these without any fuel before or after - this helps the body learn to use fats as fuel during longer, easier efforts. Using fuels during harder efforts helps to practice taking in that fuel at higher intensities and with more miles on your legs, which is when you're more likely to have any GI issues relating to taking in fuels. 4. What should I consider eating or drinking immediately before and after? For daily easy effort/recovery effort or even long runs I typically don't eat anything prior to running. Before a workout or a race I've taken a liking to onigiri. A rice ball is super convenient (make them ahead of time), very easy on the stomach, and provides some pretty quick energy. For drinks, stick with water or a good electrolyte supplement such as LMNT (even a homebrew version of this is good). Post run (more important for after more stressful efforts such as long runs, workouts, and races) get a bunch of protein (probably 30+ grams) and a good whack of carbs to help build/rebuild muscle and replenish muscle glycogen. I like sweet potatoes, sushi rice, or fruit for this. 5. What should I consider eating or drinking the day/night before a long run? Broadly, something that's not going to cause GI issues the next day. A good bit of protein is always good, but also some carbs here to help fuel the effort the next day. Again, I like sushi rice, sweet potatoes, and maybe fruit for this. For liquids, just make sure you're getting plenty of water and some electrolytes during the day. I normally stick to 6 miles or less, so have never needed to think about it. Thanks in advance for any advice on this. View Quote Quoted: That's good info, thanks.

I'm focusing mostly on 5k/10k fitness right now, but with a little more emphasis on my long runs I could probably throw down a ~2:55 marathon (~6:40/mi) and exactly ZERO of my easy runs are 8 min/mi. I typically cruise around in the 8:15-30/mi range (largely the slower end of that), with recovery runs at about 9 min/mi. Running any pace that starts with "8" is way too fast for your fitness and current ability level and you're short-changing your aerobic development. Having the biggest aerobic engine possible is what gets anyone through a marathon. Run slow to race fast. @erud |

The times I run now and have run in the past have absolutely nothing to do with running a marathon, that was just to give you guys an idea of where I am at. Historically, I run 4-6 miles 4 or 5 times per week. I used to be quite a bit faster when I was quite a bit younger, but 8 minutes is a comfortable pace for me now for those kinds of distances. I have no illusion that that transfers to an 8 minute/mile marathon pace. I think I mentioned that I was guessing/expecting to be in the 10-minute/mile neighborhood, which would be 25% slower than my normal short-distance pace. I plan to more or less continue doing what I’m doing from now until mid-June, at which point I’ll start the “official” training plan leading up to the race in October. Thanks for the input. |

Everyday runs at 60-90 (closer to 90) seconds per mile slower than marathon pace is right about where I'm at. I will say that this (the "I can't run that slowly" thing) can come about because of an underdeveloped aerobic system. Everyone always burns a mix of sugars and fats no matter what they do, including running. Running easily/slowly should skew heavily towards fat-based, while running hard/fast will skew towards using sugars. A person can be so used to using that "faster" gear that their metabolism simply can't convert fats quickly enough and so they speed up to use a fuel substrate mixture that's more "comfortable". It just takes time to develop that aerobic/fat burning engine. I'm massively faster than I was when I started running almost 7 years ago, but I can actually run slower more comfortably now (the same absolute paces, not speaking relatively) than I could back when I first started. |

I find slowing down to be more enjoyable. It just comes down to time. ‘If I run this ONE MINUTE SLOW it’s only X minutes of life.’ Well…except for marathons. 26 extra minutes is a lot. For a 15 mile long run….it’s already 2 hours long so another 15 minutes won’t kill you at that point. Crossing over 100 minutes just kinda rounds up to me.
‘Yay I saved 10 minutes and feel so exhausted. I need 10 minutes to recover.’ Mm hmm. |

Spring brand gels taste like lots of banana. They’re not disgusting. I’ve eaten them for ultras.
Today was 3.5 miles of running and hiking. I took a 1.5 L bladder of water mixed with 2 tailwind packs. I drank just about 500mL/16oz of it based on ‘fill it the whole way then empty what is left into bottles and measure’ accuracy. This was about 133 (400 total divided by 3) calories for the run/hike. Strava/Garmin said I burned over 2,000. Edit: I had homemade boboli pizza last night. 2 eggs and coffee for breakfast about an hour before the run/hike. No stomach issues and I drank by time for most of it. Mostly at mile ‘beeps’ on my watch or when I was walking uphill because it’s less to mess with. For a road marathon I would absolutely practice eating at race pace and opening the wrapper. You’ll never forget the time you DIDNT eat all that syrup GU and it smeared all inside your shorts pocket. |
