Why Most Runners Get Their Nutrition Wrong
(And How To Fix It Before Race Day)

Filmed by Luke — co-founder, chartered accountant, marathon runner.

What's Inside

7 Products.
One Decision.

Every product chosen because it represents a different approach to race-day fuelling — different carb sources, textures, and absorption strategies. Test in training. Find what works. Commit.

01
SiS — Science in Sport
Beta Fuel Gel — Strawberry & Lime

40g dual-source carbs. Maltodextrin + fructose 1:0.8 ratio. The highest carb gel in the pack. Built for athletes targeting 80–90g/hr intake.

Dual-source formula
02
OTE
Super Gel — Tropical, 40g Carb

40g carbs. Naturally flavoured. Designed to be gentle on the stomach at race pace. Widely used in the UK, rare in Irish shops.

Hard to find in Ireland
03
Precision Fuel & Hydration
PF 30 Gel — Original, 30g Carb

30g carbs. Neutral flavour. Low sweetness — more tolerable late in a race when sugar fatigue sets in. The choice of elite marathon and triathlon athletes.

Used by elite triathletes
04
GU Energy Labs
Energy Gel — Raspberry Lemonade

The US standard for endurance gels. Raspberry Lemonade is their best-selling flavour. Caffeine-free. Not sold in most Irish sports shops.

Unavailable in most Irish stores
05
Kinetica Sports
Energy Gel — Berry Flavour

The Irish brand. Maltodextrin-based, sport-banned-substance tested. See how it compares side-by-side with international alternatives.

06
Precision Fuel & Hydration
PF 30 Chew — Mint & Lemon, 30g Carb

The chewable alternative to gels. 30g carbs in solid form. For athletes who prefer texture over liquid at race pace — a completely different fuelling experience.

Chewable format
07
Puresport
Ultra Electrolyte Sachet — Watermelon Salt

Sodium, potassium, magnesium. Mix with water before or during your race. Because you're also losing electrolytes, not just carbohydrates.

Why It Exists

Stop Gambling
On Race Day.

Most Irish runners use whatever gel is at the race expo. That's usually one or two brands. The only way to know what works for your body is to test it in training first.

Test in Training,
Not On Race Day

GI issues appear at mile 18, not mile 3. You need to know your fuel works before the race starts — not find out at the worst possible moment.

7 Products You
Won't Find Together

GU, OTE and Precision Fuel are hard to source in Ireland. This pack puts all seven products in one box for less than buying them individually.

The Irish Feed.co —
Finally Here

The Feed in the US built a business on this exact concept — try before you commit. There's been nothing like it in Ireland. Until now.

How To Use It

A Simple
Protocol.

01
Use On Your Long Runs

Test one product per long training run in the 8–12 weeks before your race. Note how your stomach responds and what the texture is like.

02
Find Your One

After testing all seven, you'll know which product works for your body, your pace, and your taste preference.

03
Stock Up For Race Day

Buy a full supply of your preferred product with confidence. You've already tested it at race pace. No guesswork.

"I used to never know what gels to get or what sat well with me when it came to races or training. The lads' emails gave me the knowledge I needed and the pack helped me test this out."

"I used gels before matches and half-time before but was stuck with the same flavour and brand. The pack had different flavours and products I had never seen before and allowed me to try them before buying a whole pack of a new brand."

"I took up cycling last year and needed to understand what I needed to eat on the bike. The emails from Luke and Jamie really helped inform me in terms of nutrition and the pack helped me choose what was right for me."

"Got into hyrox and running during Covid. Sick of the same gels the whole time but the shops only stocked a few. Didn't want to commit to a full order of other brands until I tried them — this is what the marathon test pack did for me. Thanks lads!"

The Science

Why Testing
Matters.

⚠️ 3 products in this pack are not available in Irish sports shops
GU Energy Gel, Precision Fuel PF30 and OTE Super Gel are not stocked by Irish retailers. This is the only way to test them before race day.

There's no single best gel — which is exactly why testing matters. SiS Beta Fuel delivers 40g dual-source carbohydrate and is ideal for athletes targeting 80–90g per hour. Precision Fuel's neutral flavour makes it more tolerable late in a race. GU gels are the global standard but hard to find in Ireland. OTE is favoured by athletes with sensitive stomachs. The right gel is the one that works for your specific physiology — only discoverable through testing.

For a standard marathon, most athletes need 60–90g of carbohydrate per hour. This pack allows you to practice your full fuelling strategy in training so race day execution is automatic.
