NUTRITION GUIDE – ROAD RUNNING
Whether you need additional nutrition during a road running event depends mainly on how long you expect to be running, the intensity of the race, weather conditions, and your own personal preference.
For shorter races, extra fuel may not be essential. However, if you are running for a longer period of time, racing hard, or targeting an important “A race”, a simple fuelling plan can help you arrive at the start line fully prepared and keep your energy levels steadier throughout the event.
The golden rule is simple: do not wait until you feel low on energy before you start fuelling. By then, you are already playing catch-up.
Pre-Race Nutrition
Before race day, your aim is to be well hydrated, fully fuelled, and comfortable with the products you plan to use. Never try anything new on race day — race day is for execution, not experiments.
In the hours before your run, consider a pre-loading strategy using HEED 2.0, Fully Charged, or your preferred Hammer Nutrition pre-race option. Sip slowly rather than drinking everything at once, and aim to finish your pre-race drink around 45 minutes before the start.
A simple pre-race option is:
Mix your chosen pre-load drink with 500ml of water and sip gradually.
You can begin sipping your energy drink up to a few hours before your run. The earlier and more gradually you take it in, the more time your body has to absorb it comfortably.
For shorter races, another useful option is to take one Hammer Gel shortly before the start. This can provide an energy lift around 15–25 minutes into the run, which is ideal when you do not plan to fuel during the race.
Hammer guidance supports using Hammer Gel shortly before the start to add calories without disrupting the body’s use of stored muscle glycogen, while Fully Charged is positioned as a pre-exercise support product taken around 15–30 minutes before exercise.
During Your Run
Your in-race nutrition should be based on time, not just distance. A fast 10K runner and a 2-hour 10K runner have very different fuelling needs.
For races under an hour, many runners will not need extra calories, provided they start well fuelled.
For races over an hour, especially hard efforts or warm-weather events, a small fuelling boost can be beneficial. For example, if you expect to finish a 10K or half marathon in around 1 hour 30 minutes to 2 hours, taking an energy gel after approximately one hour can help support your energy through the final stages.
For half marathon runners, especially those expecting to be out for longer, a more structured plan similar to marathon fuelling may be useful.
Hammer Nutrition guidance positions Hammer Gel and HEED as suitable carbohydrate fuels for exercise lasting up to around 2–3 hours, with Hammer Gel being a good option for runners who prefer to drink plain water, and HEED being a good choice for those who prefer a flavoured sports drink.
Half Marathon & Marathon Fuelling
For half marathon and marathon distance events, the key is to start fuelling early. Do not wait until you feel tired, flat, or hungry.
A practical race strategy is:
Take 1 Hammer Gel every 30–45 minutes, or roughly every 5–6km / 3–5 miles, depending on pace, conditions, and personal tolerance.
For many marathon runners, this may result in around 5–7 gels in total, although the exact amount will depend on expected finish time.
Hammer Gel is based on complex carbohydrates rather than simple sugars, which makes it a strong option for runners who want steady energy without the classic sugar spike-and-crash feeling.
However, even with a well-tolerated fuel, stomach issues can still occur if hydration and electrolytes are neglected. In plain English: it is not always the gel’s fault — sometimes your electrolyte plan has gone missing in action.
If you choose Hammer Gel as your main fuel, make sure you also drink water regularly. Sip water at aid stations and keep your fluid intake steady rather than waiting until you are thirsty.
Hammer’s guidance recommends one serving of Hammer Gel every 30–45 minutes for events around the 3-hour range or shorter, while also continuing electrolyte support because Hammer Gel does not contain a full-spectrum electrolyte profile.
Hydration & Electrolytes
Hydration is not just about drinking water. During longer runs, warm conditions, or high-sweat efforts, electrolyte support becomes important.
Hammer Nutrition’s approach is to use a full-spectrum electrolyte strategy, rather than relying only on salt. Endurolytes, Endurolytes Fizz, Endurolytes Extreme, and Endurolytes Extreme Powder are designed to support electrolyte balance with more than just sodium.
For many runners, a useful starting point is:
Endurolytes: 1–3 capsules before exercise, then 1–6 capsules per hour as needed
Endurolytes Extreme: often suited to hotter conditions, heavier sweaters, or runners with higher sodium needs
Endurolytes Fizz: a convenient drink-based option if capsules are not preferred
Hammer guidance states that Endurolytes can be used before, during, and after exercise, with dosing affected by body weight, fitness, heat, humidity, acclimatisation, and individual sweat rate.
Energy Gel Alternatives
If gels are not your preferred option, there are other ways to fuel effectively.
HEED 2.0
HEED 2.0 is a strong choice if you prefer to take in calories through your bottle rather than using gels. It provides both calories and electrolytes, making it useful for runners who struggle to drink enough water when using gels.
Each scoop of HEED provides 110 calories and contains roughly the same electrolyte support as one Endurolytes capsule or half an Endurolytes Fizz tablet.
Perpetuem / Longer-Duration Fuel
For longer events, ultra-distance runs, or runners who need a more substantial endurance fuel,Perpetuem Solids or Perpetuem 2.0 can be considered. It is designed as a longer-duration fuel, combining carbohydrates, protein, and a small amount of healthy fat.
Hammer guidance positions HEED as a carbohydrate-only drink mix for exercise up to around 2–3 hours, while Perpetuem is better suited to longer-duration workouts and races.
Mixed Fuelling Strategy
You can also combine:
Hammer Gel + water
HEED 2.0 as your drink-based fuel
Perpetuem Solids or Hammer Bars for variety in longer events
Endurolytes for electrolyte support
As a general Hammer-style guideline, keep calorie intake controlled and steady. For many runners, the target range is around 120–180 calories per hour, depending on body size, pace, conditions, and event duration.
Little and often wins. Big dumps of calories mid-race rarely end well
Post-Race Recovery
After a hard run, half marathon, or marathon, recovery should start as soon as possible.
Aim to refuel within 20 minutes of finishing with a recovery drink such as Recoverite, followed by solid food when available.
Your post-race cravings may be shouting loudly — and fair enough, you earned them — but get your recovery nutrition in first. That is what helps begin the repair and refuelling process.
Do not rush your recovery drink. Sip it steadily rather than downing it in one go. Giving your body time to absorb it properly is the smarter move.
If you cannot access proper food straight away, a Hammer Bar or suitable protein-based snack in your kit bag is a practical option. It is simple, portable, and far better than wandering around the finish area hoping a banana appears like magic.
Hammer guidance emphasises post-exercise refuelling as a key part of future performance, with Recoverite or Vegan Recoverite recommended soon after training or racing to help refill the tank.
