Alan Murchison is a Scottish chef and elite sports nutritionist. He held a Michelin star at L'Ortolan in Berkshire from 2003 to 2014 and now runs Performance Chef — the food operation behind Specialized Factory Racing, British Cycling, and a generation of Olympic and World Tour podiums.

01Variety beats perfection — thirty-plus different plants a week supports gut diversity, immunity, and the hard-training adaptations that chicken-and-rice cannot deliver.
02Race-day nutrition has to be rehearsed in training. The start line is the worst place in the world to discover a gel disagrees with your gut.
03Real protein at every meal — 25 to 35 grams, four times a day — protects lean mass through a hard block more reliably than a single big portion at dinner.
04The thirty-minute recovery window is real, but the format is flexible. A rice bowl, a smoothie, or a structured shake all work — the timing is what matters, not the brand on the tub.
05Plant-powered performance works at the elite level, but the protein and iron maths have to be deliberate. It is not simply removing meat from a normal diet.
If you have ever wondered why two riders on the same training plan, with the same FTP, end the season in completely different shape, the answer is rarely on the bike. It is in the kitchen. On this episode of the Roadman Cycling Podcast, Alan Murchison sits down to explain why.
Alan held a Michelin star for over a decade at L'Ortolan in Berkshire. He walked away from fine dining to feed Olympic cyclists, Specialized Factory Racing, and the Canyon-SRAM women's World Tour squad. He is also a multiple World and European age-group duathlon champion who still rides hard. So when he tells you most amateur cyclists are eating themselves into a hole, he is talking from both ends of the table — the chef who knows what real food looks like, and the rider who has tested it.
Key Takeaways
The first big idea Alan keeps coming back to is variety. The cycling internet loves to argue about macros — 90 grams of carb, 120 grams of carb, 1.6 grams of protein per kilo. He is not against the maths. He is saying the maths describes about 40% of the picture. The other 60% is the range of food the maths gets paid out in. A rider hitting 3,500 calories on chicken, rice and broccoli twice a day is hitting their numbers and shorting their gut, their micronutrients, and the diversity that drives long-term recovery. Thirty-plus different plants a week is the easiest proxy for the variety that actually supports adaptation, and that is not a wellness slogan — it is the work coming out of King's College and ZOE that the better World Tour kitchens already build their menus around.
The second is rehearsal. Race-day fuelling is not a place for surprises. Every gel, every chew, every drink mix has to be tested in training first, at race intensity, on rides of the same shape as the event. Most blow-ups Alan has seen at the elite level are not training mistakes — they are nutrition strategies that worked perfectly in week eight of the build and then met an unfamiliar product, an unfamiliar drink temperature, or an unfamiliar breakfast on the morning of the race. Pros eat the same breakfast on race morning that they have eaten dozens of times. Amateurs change something on the day and call the result bad luck.
The third is recovery. The thirty-minute window is not a marketing line invented by supplement companies — it is real, and it is the cheapest improvement in the sport. Carbohydrate, protein, and fluid inside thirty minutes of finishing the work. The format is open: a rice bowl, a smoothie, a properly built shake, or even a sandwich and a glass of milk. What it cannot be is "I will eat when I get home, then have a shower, then maybe sort dinner." That hour you lost is an hour you do not get back, and it shows up two days later when the next hard session feels harder than it should.
The fourth is what Alan calls the "professional eater" mindset. Pro cyclists eat with intent four to five times a day — every meal counts, every snack counts, the kitchen is the second gym. Amateurs eat by accident. They train hard, then eat what is in the cupboard, or skip lunch because the meeting overran, or snack on whatever the kids left behind. Closing that gap does not require a chef. It requires three Sundays a year spent learning to cook six dishes properly and a kitchen stocked with real food on a Tuesday night.
Why This Episode Matters
Alan is the rare guest who has cooked at the highest level of food and trained at the highest level he can train at. That combination matters. Most sports-nutrition advice in cycling either comes from clinicians who do not eat the food, or from food influencers who do not understand the metabolic load of a four-hour ride. Alan does both. The result is a conversation that does not get lost in either direction — the food still has to taste good, and the food still has to land the macros.
For Roadman listeners trying to make the next jump, this is one of the most practical conversations we have run in 2026. There is a reason we keep coming back to nutrition on this podcast: it is the lever most amateur riders are leaving on the floor. Your training is probably already pretty good. Your food, almost certainly, is not.

PRO PRACTICE
Race-morning carbohydrate intake of 2 to 4 grams per kilogram of bodyweight 3 to 4 hours pre-event is the World Tour standard.

STUDY
Spreading 25 to 35 grams of protein across four meals is more effective for muscle protein synthesis than concentrating intake into one or two large servings.

“You could have chicken, rice and broccoli twice a day, hit every macro target on your sheet, and still be malnourished. The bigger question is not how much, it is how varied.”
“The day of a race is the worst day in the world to find out a gel does not work for your stomach. You rehearse the fuel the same way you rehearse the pacing.”
“Recovery is not a brand of shake. It is carbohydrate, protein, and fluid inside thirty minutes. If a rice bowl gets there faster than your blender, eat the rice bowl.”

How does Alan Murchison's nutrition advice differ from generic cycling diet advice?+
Murchison rejects the macro-first framing that dominates cycling nutrition. He argues that a rider hitting their carbohydrate, protein, and calorie targets while eating the same five foods on rotation is still malnourished — short on the micronutrients, fibre, and gut diversity that drive long-term adaptation. His baseline is variety first: thirty-plus different plants a week, four protein sources across the week, and training-quality food cooked properly rather than ultra-processed bars.
What does a World Tour rider actually eat on a race morning?+
Three to four hours before the start a rider typically takes on 2 to 4 grams of carbohydrate per kilogram of bodyweight, a moderate protein dose (around 20 grams), and minimal fat or fibre to protect the gut. That translates to a large bowl of rice or oats, eggs or yoghurt, fruit, and a coffee — eaten slowly, with hydration, and finished early enough that the gut has settled before the first effort.
Why is variety more important than macros for cyclists?+
Macros only describe what fuels the work. Variety describes what fuels the recovery. Gut microbiome diversity — driven by the range of plants and fibre sources in the diet — predicts immune resilience, recovery markers, and the ability to repeat hard training across weeks. A rider hitting macros on a five-food rotation typically under-eats fibre, polyphenols, and the micronutrients that support adaptation.
How long is the recovery window after a hard ride?+
The thirty-minute window is real for the first round of refuelling — get carbohydrate, protein, and fluid in fast. After that, the window stays open for several hours but the rate of glycogen resynthesis slows. The practical rule is to eat or drink something proper within thirty minutes, then have a real meal inside two hours, with the protein dose around 25 to 35 grams in each.
Can you race seriously on a plant-based diet?+
Yes, but it requires deliberate planning. Murchison's plant-powered work with elite athletes shows the model works when protein is hit through varied sources (legumes, soy, quinoa, fortified options), iron is monitored, and B12 is supplemented. Most amateurs who go vegan and lose performance simply remove the meat without rebuilding the protein structure of every meal.
