A Practical Guide

DIY Running Nutrition

One week of store-bought gels costs $50. The same carbs, made at home, cost $9 — and taste better. Here's exactly how.

If you're triathlon training, ultra running, or deep in a marathon block pulling 10–17 hours of cardio a week, you need a lot of carbs to keep the body ticking. Buying gels works, but it's expensive and you have no control over what's in them. This guide walks through two home-made recipes — a pocketable energy bite for easy days and a squeeze-pouch gel for speed work — both cheaper than store-bought by nearly an order of magnitude.

"You can reduce your running nutrition cost from $200 a month down to about $20 a month. One-tenth the cost."

01 The Cost Story

The whole reason this matters. Per-unit cost, compared honestly against the gels you'd actually find at a running store today.

Store-bought week

$50

One week of running gels at normal training volume.

Homemade, same carbs

Same carb load, made at home from bulk ingredients.

Marathon block

$200→$20

Monthly nutrition spend can drop to one-tenth.

Per-gel equivalent

~10×

Seven to ten times cheaper than buying the name brands.

Cost per gel-equivalent

Spring Energy

$4.00

Maurten

$4.00

Muir Energy

$3.30

DIY energy bites (×2)

$0.43

DIY gel pouch (half)

$0.57

Each row shows the cost of one gel's worth of carbs (~25 g). Two homemade energy bites equal one gel; half a 5 oz homemade pouch equals one gel.

02 Buy vs. Make

There are real tradeoffs. Making your own isn't strictly better — it just wins hard on cost and control.

Store-bought

Pre-packaged Gels

Convenient and consistent, but pricey and opaque.

Grab it anywhere in the world
A gut-tested brand travels with you
Long shelf life, no prep
Expensive — $3–$4 per gel
No control over the ingredient list
Packet waste every workout

Homemade

DIY Energy Fuel

Cheaper, customizable, reusable — with a few real drawbacks.

7–10× cheaper per gel-equivalent
Full control over ingredients
Reusable pouches, less trash
Honestly kind of fun
Takes prep time
Shorter shelf life — fridge/freezer only

Who this is for Endurance athletes in heavy training blocks — marathon, ultra, or triathlon — who are burning through gels fast enough that the cost actually hurts. If you race twice a year and use three gels total, the math doesn't matter. If you're eating 6+ gels on every long run, it matters a lot.

03 The Core Ingredients

Both recipes share the same backbone: dates and applesauce as the carb base. Everything else is there to adjust texture, flavor, or use case.

🌴Medjool DatesThe foundation — packed with fast carbs

🍎ApplesauceAdds moisture, sweetness, easy carbs

🥜PB PowderFat-stripped peanut; flavor + texture

🌾Rolled OatsBlended into oat powder; thickens bites

🍫Mini Choc ChipsOptional — texture and joy

🧂Coarse SaltCuts sweetness, replaces electrolytes

🫐Mixed BerriesFlavor base for the gel pouch version

🥥Coconut SugarOptional carb + sweetness boost in gels

Why peanut butter powder, not peanut butter Regular peanut butter is half fat, and fat is slow to digest — not what you want mid-run. PB powder has the fat extracted, leaving ~8 g protein and ~6 g carbs per serving. It adds the taste and creamy consistency without slowing you down.

04 The Recipes

Two versions for two use cases. Energy bites are solid and chewy — best for easier efforts where you can take a second to chew. Gel pouches are fluid and go down fast — built for speed workouts and long efforts where you don't want to slow your cadence.

Recipe 1 · Energy Bites

Date & Applesauce Carb Bites

For zone 1–3 training and long easy runs. Chewy, pocketable, and kid-approved.

Rolled Oats1½ cups, blended into oat powder

PB Powder½ cup

Applesauce2 cups

Medjool Dates1 full bag, pitted

Mini Chocolate Chips½ cup (optional)

Coarse SaltA good pinch — balances the sweetness

Method Blend the oats into a fine powder, then combine in a bowl with the PB powder. Separately blend the applesauce and dates until smooth — no big chunks. Fold the wet mixture into the dry, then stir in chocolate chips and salt. Spoon small portions onto wax paper, twist the paper like a Tootsie Roll wrapper, and freeze. Pull out what you need the night before a run.

Recipe 2 · Gel Pouches

Berry Squeeze Gels

For speed workouts, marathon pace efforts, and long runs where you want fast-absorbing fuel and can't slow down to chew.

Medjool Dates150 g (weigh for accuracy)

Applesauce1 cup

Frozen Mixed Berries2 cups (or any fruit you like)

Coconut Sugar¼ cup (optional — adds carbs + sweetness)

WaterA splash, to help it blend smooth

Reusable Pouches5 oz, with screw top & zip seal

Method Blend everything until completely smooth — no chunks, or they'll clog the pouch nozzle. Err on the thinner side; thick gels are miserable at race pace. Transfer to a pitcher with a pour spout, then fill each pouch about 3/4 full (it'll spread when you pinch it closed). Seal, label, and freeze. Pull one into the fridge the day before you need it.

55 oz pouches per batch

~40.5 gCarbs per pouch

10Gel-equivalents per batch

$5.73Total batch cost

$0.57Per gel equivalent

Pouches are basically two gels in one A 5 oz pouch holds ~40 g of carbs — way more than the ~25 g in a standard gel. Treat each pouch as two servings: take half, run another 25 minutes, take the other half. On an 18-mile hilly long run, three pouches = six gels worth of fuel across the whole effort. Pouches also come in 3 oz and 7 oz if you want to target different dose sizes.

05 When to Use Which

Both recipes work; they're just tuned for different efforts. The bites are built around texture and slower eating; the gels are built for speed.

Which fuel for which session

Zone 1–3

Energy Bites Easy long runs, base miles, anything under half-marathon distance. 3 bites covers ~10–13 miles.

Zone 3–4

Either Marathon-pace long runs — pick whichever sits better in your stomach that day.

Zone 4–5

Gel Pouches Speed workouts, half-marathon pace, long hill efforts. Fluid fuel absorbs faster at high intensity.

06 Storage & Ground Rules

Rule	Why it matters
Freeze the batch, fridge what's next	No preservatives means a ~1 week fridge life. Freeze everything, then transfer 2–3 days worth to the fridge as you go.
Blend gels smooth — no chunks	Pouch nozzles are small. Even a small chunk of fruit can clog one mid-run. Over-blend rather than under-blend.
Go thinner on gels, not thicker	Thick gels are brutal to swallow at speed-workout pace. A touch of water is worth it.
Don't overfill pouches	Fill to ~3/4. Pinching the seal pushes the level up — more than that and you'll overflow the zip.
Chase bites with water	Bites are denser than gels. A few sips of water after each one helps them digest quickly.
Add the salt	The wife was right: a pinch of coarse salt balances the sweetness of dates + applesauce and doubles as electrolytes. Don't skip it.
Max two pouches in one pocket	More than two 5 oz pouches in a shorts pocket and you'll feel every step. Spread them across belt + pack + shorts.

Shelf life & travel This is the real downside. Store-bought gels live in a drawer for a year and fit in carry-on luggage without a thought. Homemade fuel needs a fridge or freezer and doesn't travel well. Most endurance athletes end up doing both — DIY for training at home, store-bought for travel and race day.

07 The Takeaway

The real lesson isn't that homemade gels taste better or that dates are magic — it's that gel-shaped carbs are wildly overpriced. Once you see that two ingredients (dates and applesauce) hit the same macros as a $4 gel for about 50 cents, the math on a marathon block changes completely. Make a batch of each on a Sunday, freeze them, and a whole week of long-run fuel takes 30 minutes of prep and costs less than a single Spring Energy.

"This is even better than I originally thought — same carbs, same feeling on the run, one-tenth the cost."
