Walk into any running club or cycling café and you will see the same thing in back pockets: gels, chews and bars with ingredient lists as long as the route. Some athletes have quietly gone the other way. They carry dates.
This is not nostalgia. Dates happen to deliver the exact thing endurance and team-sport athletes need most, fast carbohydrate, in a form with one ingredient. This guide covers where dates fit across a training week, how many to eat, where they fall short, and how they compare on cost with commercial sports fuel.
Carbohydrate Is the Currency of Training
Carbohydrate is the main fuel for moderate to high-intensity exercise. Your muscles store it as glycogen, and when those stores run low, pace drops and effort feels harder.
Sports nutrition guidelines from bodies such as the American College of Sports Medicine and the International Society of Sports Nutrition broadly recommend:
|
Training Phase |
Carbohydrate Guideline |
What That Means for a 70kg Athlete |
|
1 to 4 hours before |
1 to 4g per kg of body weight |
70g to 280g, usually as a meal plus snack |
|
During exercise over about 60 minutes |
30 to 60g per hour |
30g to 60g per hour |
|
During exercise over about 2.5 hours |
Up to 90g per hour, using mixed sugars |
Up to 90g per hour |
|
Rapid recovery (next session within 8 hours) |
About 1 to 1.2g per kg per hour for the first 4 hours |
70g to 84g per hour |
Dates can cover a meaningful share of every one of those phases.
What Dates Bring to an Athlete's Diet
Fast, Mixed Carbohydrate
One Medjool date provides roughly 16g to 18g of carbohydrate. In soft, fully ripe dates, most of the sugar is a mix of glucose and fructose.
That mix matters. Glucose and fructose are absorbed through different transporters in the gut. Research on "multiple transportable carbohydrates" shows that combining them lets athletes absorb more carbohydrate per hour than glucose alone, which is why many commercial sports drinks and gels now use a glucose and fructose blend. Dates deliver a natural version of it.
Potassium
Dates contain about 650mg to 700mg of potassium per 100g. Potassium supports muscle contraction and fluid balance. Three Medjool dates give you around 500mg.
Magnesium
About 40mg to 55mg per 100g. Magnesium plays a role in energy metabolism and muscle function.
A Short, Simple Ingredient List
Plain dates contain dates. No flavourings, no preservatives, no sweeteners. For athletes in tested sport, supplements carry a risk of contamination with banned substances, which is why anti-doping bodies advise using only batch-tested products. A whole food like a date is a different category of risk from an unregulated supplement.
Where Dates Fall Short (and How to Fix It)
Truth be told, dates are not a perfect sports food. Three limits are worth knowing.
|
Limitation |
Why It Matters |
Simple Fix |
|
Very low in sodium |
You lose sodium in sweat; dates will not replace it |
Add a pinch of salt, salted nuts, or an electrolyte drink |
|
Fibre content |
About 7g per 100g can upset some stomachs during hard efforts |
Eat them 45 to 60 minutes before hard sessions; test in training first |
|
Low in protein |
Recovery needs protein as well as carbohydrate |
Pair with milk, Greek yoghurt or a protein shake |
Gut training matters. If you plan to use dates in a race, practise with them in long training sessions first. Your gut adapts to carbohydrate intake during exercise, and race day is not the day to try something new.
A Sport-by-Sport Fuelling Matrix
Different sports place different demands on your fuel. Here is how dates fit.

For fasting athletes, our guide to the best dates for energy boosts during Ramadan in the UK covers timing around iftar and suhoor.
Worked Example: A 70kg Runner's Long Sunday Run
-
Two hours before: porridge with banana and 2 chopped dates (about 80g carbohydrate)
-
During a 2-hour run: about 45g carbohydrate per hour, or roughly 3 Medjool per hour, taken in halves every 20 minutes, with water and an electrolyte tab
-
Within an hour after: a large glass of milk and 3 dates with a handful of salted nuts
What the Research on Natural Fuel Shows
Direct research on dates and sports performance is still limited. The closest evidence comes from studies on dried fruit.
A 2012 study in the Journal of the International Society of Sports Nutrition compared raisins with commercial sport chews in 11 trained male runners. After 80 minutes of steady running, they completed a 5km time trial. Both raisins and the sport chews improved performance compared with water only, and there was no meaningful difference between the two.
Raisins are not dates, and one small study is not proof. But it supports the idea that dried fruit can match commercial chews for performance during endurance exercise. A 2025 review in Food described dates as a promising functional food for athletic performance and recovery. Even so, human trials that test dates directly in athletes remain few.

Cost Comparison: Dates vs Commercial Sports Fuel

Fuel |
Carbohydrate per Serving |
Typical Cost per Serving |
Cost per 25g Carbohydrate |
|
Energy gel |
20g to 30g |
Often £1 to £2.50 |
About £1 to £2.50 |
|
Sport chews (per pack) |
About 40g to 50g |
Often £2 to £3 |
About £1 to £1.90 |
|
Roots Athlete & Gym Bundle dates |
About 25g in 37g of dates |
About £0.74 |
About £0.74 |
Date cost is based on the bundle price of £26.99 for 1.35kg at the time of writing. Gel and chew prices vary widely by brand and pack size.
Dates are not free. They are, in most cases, cheaper per gram of carbohydrate than branded gels, and you are not paying for packaging, flavouring and marketing.
Choosing Varieties for Training
-
Medjool: soft and fast to eat. The go-to before and during sessions. For more detail, read why Medjool dates are the ultimate pre-workout fuel.
-
Sukri: light, golden and easy to digest. A good post-training option.
-
Ajwa: dense and less sweet. Better a couple of hours before, or as part of an everyday diet.
A UK Weather Tip
Soft dates firm up in the cold. On a January long run, keep a few in an inside pocket so they stay easy to chew. In summer, a small zip bag stops them getting sticky in a saddlebag.
The Roots Athlete & Gym Bundle
The Roots Athlete & Gym Bundle brings together Ajwa, Medjool and Sukri in three 450g packs for £26.99, saving £4.98 on buying them separately. That is roughly a month of training fuel for someone eating two to three dates on training days.
Every Roots date is unpolished and unglazed, with no added sugar or preservatives. UK delivery takes 2 to 4 working days. Explore more on the Roots Products homepage, and for all-day eating around training, read how premium dates support healthy energy levels throughout the day.

Frequently Asked Questions
Are dates good for athletes?
Yes. Dates provide fast carbohydrate from a natural mix of glucose and fructose, plus potassium and magnesium. They work well before, during and after training when paired with sodium and protein where needed.
How many dates should I eat during a long run or ride?
Aim for 30g to 60g of carbohydrate per hour for efforts over an hour. That is roughly 2 to 4 Medjool dates per hour, taken in small amounts every 20 to 30 minutes.
Can dates replace energy gels?
For many athletes in training, yes. A small study found dried fruit matched sport chews for performance. For races, test dates thoroughly in training first, and add electrolytes because dates contain almost no sodium.
Are dates good after a workout?
Yes, especially paired with protein. Dates help refill glycogen, and milk, yoghurt or a protein shake supports muscle repair.
Do dates cause stomach problems during exercise?
Some people find the fibre uncomfortable during hard efforts. Eat dates 45 to 60 minutes before intense sessions and practise with them in training.
