AMATEUR CYCLIST FUELLING BENCHMARKS 2026: AUDIT YOUR RIDE

The Amateur Cyclist Fuelling Benchmarks Report 2026 is now published. Its first finding is editorial rather than physiological: Roadman does not have a representative population dataset showing what the average club rider eats per hour. We will not turn coaching observations into a fake national benchmark.

This is therefore an evidence-benchmark edition. It gives you a reference range, a repeatable audit and a way to separate a fuelling problem from pacing, fitness, heat, illness or logistics. The useful comparison is not “do I eat like a professional?” It is “did my practised plan support the demand I chose?”

For the direct question “how many grams per hour?”, use the maintained carbohydrate-per-hour cycling guide. For a calculated starting point, use the cycling fuelling calculator. This report owns the audit: how to compare the target with what happened.

The 2026 evidence benchmark

The joint Academy of Nutrition and Dietetics, Dietitians of Canada and American College of Sports Medicine position paper recommends matching food and fluid to the athlete, task and conditions and referring athletes for an individual plan where appropriate (PMID 26920240). The duration bands commonly derived from this evidence base are starting ranges, not pass marks:

The wording matters. “Up to 90” is not “at least 90.” A range does not prove the bottom is under-fuelling or the top is optimal. It organises the first test.

Research on multiple transportable carbohydrates helps explain why glucose plus fructose can increase exogenous carbohydrate delivery at high intakes compared with glucose alone, particularly in endurance exercise lasting three hours or more (PMID 20574242). It does not prove one branded product, a universal 2:1 ratio or 120 g/h for every cyclist.

Benchmark 1: define the work

Record the ride duration, planned intensity, terrain, likely continuous climbing, weather, whether it is training or competition, the previous meal and how soon another key session follows.

Two rides of three hours can have different fuelling needs. One is a steady social ride after breakfast with easy access to bottles. The other is a mountain event with repeated hard climbs, heat, technical descents and no safe opportunity to unwrap food. Duration alone cannot resolve that difference.

Confirmed means the session demand and fuelling purpose are explicit. Partial means you know the duration but not the intensity, environment or next-session context. Not demonstrated means the target was copied from another rider or a product advert.

Next action: write one sentence explaining why this ride needs this target.

Benchmark 2: turn grams into a real plan

List every bottle, gel, bar, banana, rice cake or other carbohydrate source. Use the label or recipe, not an assumed “one gel equals one serving.” Add the carbohydrate available, divide it across the planned duration and decide how it will be accessed.

Separate carbohydrate from fluid. A high-carbohydrate bottle can be useful, but losing it should not remove the whole plan. A concentrated bottle can also create a different taste and gastrointestinal load from the same carbohydrate spread across fluid and solids.

Confirmed means the numbers reconcile with products actually carried and the rider can explain which item is used in each hour. Partial means total carbohydrate is known but access, concentration or spare capacity is unclear. Not demonstrated means the plan is a headline number without a product count.

Next action: pack the ride before it starts, then photograph or list what comes back.

Benchmark 3: measure actual intake

Planned intake and actual intake are different variables. At the finish, count what was consumed. Record dropped bottles, unopened food, feed-station changes and the point when intake became difficult.

Calculate:

1. total carbohydrate actually consumed;
2. divided by total riding time, with stop time recorded separately;
3. compared with the planned amount;
4. alongside when the shortfall occurred.

A rider who plans 80 g/h for four hours but returns with half the food has not tested 80 g/h. They have tested something lower with an execution failure. The fix may be access, taste fatigue, pacing or a reminder—not more physiology.

Confirmed means planned and actual intake are close enough that the target was genuinely tested. Partial means intake drifted but the reason is recorded. Not demonstrated means consumption is estimated from memory without knowing what remained.

Next action: make the plan easier to execute before raising the target.

Benchmark 4: evaluate tolerance without forcing it

Record nausea, bloating, reflux, cramps, urgency, vomiting and the time symptoms started. Also record heat, intensity, product concentration, recent illness, pre-ride food and medications that may affect the gut. Symptoms have multiple possible causes.

A 2023 systematic review found only eight gut-training or feeding-challenge studies. Repeated carbohydrate feeding reduced gut discomfort or malabsorption in some studies, while other outcomes were unclear or unchanged (PMID 37061651). A 2024 systematic review also described carbohydrate gut training and some dietary approaches as promising, but the included evidence was limited (PMID 39599638).

That supports progressive rehearsal. It does not support a universal instruction to add 10 or 15 grams every week, promise adaptation in eight weeks or force persistent symptoms.

Confirmed means the intended amount and products have been tolerated in more than one representative session. Partial means one test worked or manageable symptoms remain. Not demonstrated means event-day intake has never been rehearsed.

Next action: change one variable—amount, concentration, product, timing or early pacing—and repeat. Persistent, severe or unexplained symptoms warrant a qualified clinician or sports dietitian.

Benchmark 5: judge the ride in context

Record late-ride power or pace if useful, RPE, ability to hold a controlled line and cadence, cognition, mood, hunger and what happened before the next key session. Do not diagnose glycogen depletion from one slow final hour.

A late fade can reflect:

• starting too hard;
• insufficient fitness or durability;
• heat, dehydration or altitude;
• illness, pain or poor sleep;
• inadequate pre-ride or in-ride carbohydrate;
• a mechanical, route or group-riding problem.

The newest umbrella review located systematic reviews and meta-analyses that generally support carbohydrate during endurance exercise, while warning that more rigorous work is needed to transfer results into real practice (PMID 41885724). That is a useful boundary: fuelling matters, but a field result still needs interpretation.

Confirmed means repeated comparable rides show the plan supports the required work without an unresolved execution or tolerance problem. Partial means the ride succeeded once or the cause of a problem is still ambiguous. Not demonstrated means the target has not been linked to a comparable outcome.

Next action: repeat a comparable ride rather than changing training, pacing and nutrition at once.

Benchmark 6: protect energy availability and recovery

Hourly carbohydrate is only one part of the day. A rider can hit 60 g/h and still under-eat across the week. Another can complete a short ride with water and still be adequately fuelled because the surrounding meals match the task.

The energy-availability guide owns the health boundary. The energy-availability estimate is an educational calculation, not a diagnosis. Recurrent fatigue, menstrual disturbance, low libido, bone stress injury, unexpected weight change, persistent illness or declining performance needs appropriate clinical and nutrition assessment rather than a higher gel target alone.

A meta-analysis found no overall endurance-performance advantage from periodised carbohydrate restriction compared with normal carbohydrate availability (PMID 34001184). This does not make every low-carbohydrate session harmful. It does challenge claims that routinely withholding carbohydrate is automatically superior for performance.

Confirmed means the in-ride plan sits inside adequate daily intake and supports the next required session. Partial means the ride target is known but the surrounding day is not reviewed. Not demonstrated means low intake is being used for weight loss or “fat adaptation” without monitoring health, recovery or performance.

Next action: audit the whole training day before optimising one bottle.

The female-athlete evidence gap

Female cyclists should not be treated as smaller male cyclists. They also should not be given a lower carbohydrate number just because the research base is incomplete.

An audit of 937 studies underlying acute-carbohydrate guidance found that women represented about 11% of 11,202 participants; roughly 79% of studies used male-only cohorts, and very few were designed for high-quality sex comparisons (PMID 36251373).

The responsible response is:

• secure adequate energy and carbohydrate availability;
• start from the task-based range rather than automatically lowering it;
• track individual symptoms, cycle context where relevant, performance and recovery;
• involve a sports dietitian when menstrual disturbance, low energy availability, pregnancy, diabetes, gastrointestinal disease or other clinical complexity is present.

The evidence gap is a reason for careful individualisation, not a licence for a menstrual-phase calculator with unsupported precision.

Three worked audits

Ninety-minute steady ride after breakfast

The rider plans water and carries emergency carbohydrate. The session remains easy, finishes as intended and is followed by a normal meal. This does not fail because the hourly intake is below 30 g. The rider should monitor whether the same approach still works when duration or intensity rises.

Three-hour hard group ride

The rider targets 60 g/h: one 30 g bottle and one 30 g food item each hour. They consume the first two hours but bring most of hour three home because the pace rises. The recorded average is about 40 g/h, with the shortfall concentrated when access becomes hard. Before increasing the target, the rider should make hour-three fuel easier to reach and rehearse eating under group-ride pressure.

Six-hour mountain sportive

The rider has progressed toward 80–90 g/h across repeated long rides, using products available on event day. They also record water access, climb timing, feed stops and temperature. This is a relevant test. Jumping from 50 to 120 g/h on event morning because professionals report it is not.

What this report does not prove

1. No Roadman population sample. We are not publishing an average, percentile or prevalence estimate for amateur cyclists.
2. No universal optimum. The ranges are decision starts, not proof of one best number for an individual.
3. No validated fuelling score. Confirmed, partial and not demonstrated describe evidence coverage; they do not predict finishing time or health.
4. No product ranking. A branded gel, drink or hydrogel is not superior merely because it fits the arithmetic.
5. No clinical diagnosis. The audit cannot diagnose gastrointestinal disease, diabetes, RED-S, allergy or another medical condition.

Methodology

Roadman mapped the report to the established sports-nutrition position paper, the multiple-transportable-carbohydrate mechanism, current systematic reviews of gut training, the female-athlete representation audit, carbohydrate-restriction meta-analysis and the 2026 umbrella review. We then converted those boundaries into an auditable plan-versus-actual worksheet.

Coaching experience informed the questions—not a population estimate. Podcast comments are practical context, not substitutes for the linked literature.
