THE SHORT ANSWER

The complete guide to fuelling for cycling performance. In-ride nutrition, race weight, body composition, protein, hydration, and the science of eating to ride faster — from the Roadman Cycling Podcast.

Cycling nutrition is built on three layers: daily fuelling that supports your training week, in-ride carbohydrate intake that protects performance during long or hard rides, and recovery nutrition that drives adaptation. Aim for 60-90g of carbohydrate per hour on rides over 90 minutes, eat to support your training stress (not to restrict to a target weight), and prioritise protein every 3-4 hours throughout the day. Most cyclists improve more from fixing their fuelling than from any other single change.

The science of cycling nutrition has changed faster than any other endurance discipline in the last five years. Carbohydrate intake recommendations have roughly doubled. Race-weight thinking has been replaced by fuel-for-the-work-required. The role of protein and sleep has been moved from "recovery" to "performance". This guide brings the current best evidence together — drawn from conversations with the nutritionists who actually feed the World Tour.

In this guide:


Daily Fuelling: Eat to Train, Train to Eat

The single most important shift in modern cycling nutrition is the move from a fixed daily calorie target to fuelling for the work required. The idea is simple: eat to support tomorrow's training, not to enforce an arbitrary deficit.

Practical baseline for an amateur training 8-12 hours per week:

MacroDaily Target
Carbohydrate4-6 g/kg on easy days, 6-10 g/kg on hard/long days
Protein1.6-2.2 g/kg every day (split across 4-5 meals)
FatFill the rest — focus on whole foods, omega-3s, olive oil

Energy availability — calories in minus exercise calories burned, divided by lean body mass — should sit at or above 30 kcal/kg/lbm/day. Drop below 30 and you start to lose hormonal function, recovery capacity, and (eventually) bone density. Most under-fuelled cyclists cluster between 20 and 28 — fast in week one, broken by week eight.

In-Ride Nutrition: How Much, What, When

The current consensus from World Tour nutritionists is dramatically higher than the 30-60g/hour guidance most amateurs grew up with:

Ride Duration / IntensityCarbohydrate Target
Easy ride under 90 min0-30g/hour
Endurance ride 2-4 hours60-90g/hour
Hard interval session 60-120 min60-90g/hour
Race or ultra (4+ hours)90-120g/hour with multiple transportable carbs

Glucose alone tops out around 60g/hour — beyond that you need a 2:1 glucose:fructose mix to use multiple gut transporters. Modern gels and drink mixes are formulated for exactly this.

Train your gut. The reason most amateurs feel sick at 90g/hour is because they've never trained the absorption pathway. Build it: start at 60g/hour, hold it for 4-6 weeks, then add 10g every 2 weeks until you're race-ready.

Recovery Nutrition: The 0-4 Hour Window

The biggest recovery wins are won in the four hours after a hard or long session. The structure that works:

  • 0-30 minutes: 1.0-1.2g/kg carbohydrate plus 20-40g protein. Liquid is fine if appetite is suppressed.
  • 30-120 minutes: A balanced meal — carbohydrate, protein, vegetables. This is the meal that does the structural work.
  • 2-4 hours: A second carbohydrate-rich meal, especially before back-to-back hard days.

Sleep is the second half of recovery and is non-negotiable. 7-9 hours, with the same wake time daily, beats every recovery supplement on the market.

Race Weight Without Losing Power

The cyclists who get to race weight cleanly do four things:

  1. Pick a realistic target. A 2-4% drop in body weight without losing power is the achievable end of the curve. More than that risks performance and health.
  2. Lose weight in the off-season, not in race build-up. A small daily deficit (200-400 kcal) over 8-12 weeks moves the dial without compromising key sessions.
  3. Protect protein and fuelling around hard rides. Cut carbs on rest days; never on quality days.
  4. Strength train through it. Heavy lifting protects lean mass and maintains the power side of the W/kg equation.

If your weight loss strategy is "eat less, ride more", you're optimising for short-term scale movement and long-term plateau. The smarter play is body composition — fat down, muscle stable, power preserved.

Hydration: A Simpler Answer Than the Industry Suggests

The hydration industry sells complexity. The actual science is simple:

  • Daily: Drink to thirst plus enough to keep urine pale yellow. Water plus food sodium is sufficient for most amateurs.
  • In-ride: 500-1000ml/hour depending on heat, humidity, and effort. Add 500-1000mg sodium per litre when sweating heavily or riding over 90 minutes.
  • Post-ride: Replace 125-150% of body weight lost over the next 4-6 hours with fluid plus sodium.

Hyponatraemia (over-drinking diluting blood sodium) is more common in amateur ultra-endurance racing than dehydration is. Match fluid to need; do not pre-emptively over-drink.

Common Nutrition Mistakes

Mistake 1: Under-fuelling hard sessions. Quality intervals deserve quality fuel. 60g/hour minimum on any session over 75 minutes; more on intervals.

Mistake 2: Treating every ride identically. Recovery rides need very little fuel. Long Saturday rides need a lot. Match the food to the work.

Mistake 3: Chasing low body fat in race week. The pre-race diet has done its job by the start of taper week. Race-week intake should top up glycogen, not strip body fat.

Mistake 4: Sourcing nutrition from supplement marketing instead of evidence. Most "cycling-specific" supplements have no published performance data. Caffeine, beetroot juice, creatine (yes, even for endurance), and adequate protein cover the evidence-backed ground.

What the Experts Say

The insights behind this guide come from direct conversations on the Roadman Cycling Podcast:

  • Tim Spector — Professor of Genetic Epidemiology, ZOE — on why individual metabolic response to identical foods varies enormously, and how amateurs can use that.
  • David Dunne — World Tour performance nutritionist, founder of Hexis — on the daily logistics of feeding a Grand Tour rider.
  • Tim Podlogar — sports nutritionist and carbohydrate-metabolism researcher — on what 90-120g/hour fuelling actually does in the gut and the muscle.
  • Alan Murchison — Michelin-star chef turned sports nutritionist — on how to make high-carb fuelling actually edible across a long season.

Frequently Asked Questions

How many carbs per hour should I eat on a long ride? 60-90g/hour for most rides over 90 minutes; 90-120g/hour for racing or ultra. Use a glucose:fructose mix in gels and drinks to access multiple gut transporters. Build up gradually — your gut needs to adapt.

What should I eat the night before a hard ride? A balanced meal with familiar carbohydrate sources — pasta, rice, potatoes — plus a moderate protein portion. Avoid high-fat or high-fibre meals that slow gastric emptying. Top up with a small carbohydrate snack 2-3 hours before the ride.

Can I lose weight while cycling without losing power? Yes — with a small daily deficit (200-400 kcal), high protein intake, and strength training. Lose weight in the off-season, not during peak training. Fast weight loss almost always costs power.

What's the best post-ride recovery food? A meal with 1.0-1.2g/kg carbohydrate and 20-40g protein within 30-60 minutes of finishing. Whole-food options work as well as recovery shakes for most amateurs. Sleep does most of the rest.

Do I need to take supplements? For most amateurs: caffeine before quality sessions, sodium during long rides, creatine year-round, and a vitamin D check in winter. Beyond that, food beats pills.

Is intermittent fasting good for cyclists? For weight loss in some athletes, yes. For performance, almost never. Fuelling around training and protein distribution across the day matter more than meal timing. If IF makes either worse for you, it's costing you fitness.

COMMON QUESTIONS

FREQUENTLY ASKED

How many carbs per hour should I eat while cycling?+

For rides over about 90 minutes, aim for 60–90g of carbohydrate per hour, reaching the higher end only once you've trained your gut to absorb it. Easy rides under an hour usually need little or no fuelling.

What should I eat before a long ride?+

Eat a carbohydrate-rich meal 2–3 hours before — porridge, toast or rice work well — keeping fat and fibre moderate to avoid stomach trouble. Top up with a small snack in the final hour if the ride is long or hard.

Should I ride fasted to lose weight?+

Fasted riding has a place for easy, low-intensity sessions, but it doesn't burn meaningfully more fat over time and it compromises quality on harder days. Fuelling for the work required is the more reliable route to both performance and body composition.

How much protein do cyclists need?+

Endurance cyclists generally need around 1.6–2.0g of protein per kilogram of bodyweight per day, spread across meals. Intakes at the higher end help protect muscle when training hard or eating in a deficit.
