About Road Cycling
Road cycling encompasses a continuum of both team and individual events including time trials, criteriums and road races of varying distances, from 10km to 250km, held as a single day or over several consecutive stages. A high aerobic capacity and ability to sustain high power outputs is advantageous. Anaerobic capacity is also essential for performance in breakaways, hill climbs and all-out sprints.
For road cyclists the majority of training occurs on the road, with distances of 400-1000km covered each week at the elite level and 300km or more per week for serious club level cyclists. Training programs are planned to peak for specific races or tours within the season. For elite cyclists, little training may occur at the height of the competition season because they are continually racing.
Interval training and altitude training may be used to enhance performance. Indoor sessions (on rollers or wind or resistance trainers) may be undertaken when the weather is unpleasant or specific training is required (e.g. high intensity sprints, starts, technique). Elite cyclists generally only undertake other types of training such as strength training and cross-training during the ‘off season’.
Depending on the specilisation of the cyclist and their role in the team, physical characteristics vary. Time-trialists and sprinters typically have more muscle mass so to generate more power. Time-trials require an ability to sustain high, constant power outputs for the duration of the race. In road races, a high power-to-weight ratio with low body fat levels is favourable, particularly for hill-climbers as being smaller and lighter makes efforts easier.
Some cyclists deliberately under-eat during high-volume training blocks but this is not conducive to performance and increases the risk of illness and injury. Instead, cyclists need to find a realistic body weight and nutriton plan that can achieve desired body composition without sacrificing health or performance – a Sports Dietitian can help. The off-season and early season allows riders is often used for making adjustments to body composition as this is more difficult once competition starts.
To support the long hours of training for road cyclists, a nutrient rich diet is necessary. Carbohydrate needs should match training loads and timing of meals and snacks should be planned to ensure adequate refueling, repair and adaption. This is especially when there are multiple training sessions in a day, during high-volume training blocks. Daily carbohydrate requirements depend on training demands but typically range from 4-7g/kg/day for club cyclists to more than 8g/kg/day for elite cyclists.
Frequent meals and snacks can help meet energy and carbohydrate needs when requirements are high. Including protein rich foods spread evenly over the day helps to promote adaption and recovery.
Athletes with a restricted energy budget should plan the timing of their meals to be able to eat soon after training to maximise recovery. Recovery snacks or meals should be nutrient-rich (carbohydrate, protein and micronutrients) – for example fruit, diary, wholegrains and lean proteins – to ensure that nutrition needs are met within energy budget.
Road cyclists should aim to drink enough fluids each day to replace fluid losses, adapting their fluid intake to factors which impact fluid losses such as temperature, wind, sweat rate, training intensity, duration and altitude.
The aim is to start any session well hydrated. This requires drinking regularly throughout the day leading up to training or competition. Having a drink with all meals and snacks and sipping on fluids regularly during training is a good start.
It is not necessary or practical to replace all fluid losses during a training session or race. Instead, aim to replace 150% of the fluid volume lost over ~4-6 hours following the session. Sports drinks can be useful for meeting fuel (carbohydrate) needs as well as fluid needs during long or hot training sessions and in competition. Drinking water while consuming salt-containing foods (e.g. bread or crackers) can be as effective as specialised rehydration drinks for replacing fluid losses in the recovery period.
Eating before competition
The body only has a limited supply of carbohydrate in the muscles and liver. Since carbohydrate is main source of fuel for the body during high intensity exercise, muscle fuel stores should be topped over in the 24-36 hours before competition to enhance endurance performance.
Depending on the length of the race, a cyclist may need a high-carbohydrate diet for 1-2 days leading in to an event. Choosing low fibre foods and making use of of compact carbohydrate foods or liquids in the last 12-24 hours before an event helps to reduce the stomach contents to reduce the risk of gastrointestinal upset.
On race day, the final pre-event meal should be eaten ~3-4 hours before the start. Foods chosen should be rich in carbohydrates and low in fat and fibre to to aid digestion and prevent stomach issues. If the athlete is nervous or solids don’t sit well a liquid carbohydrate (e.g. smoothie) is a good alternative. Some other suitable ideas include:
- Porridge with milk and fruit
- Rice based dish (e.g. risotto)
- Pasta with beef mince in tomato-based sauce
- Fruit smoothie
- Baked potatoes
A smaller snack may also be eaten 1-2 hours before. Some suitable pre-race snack ideas include:
- Creamed rice
- Yoghurt with banana
- Fruit toast with peanut butter
- Muesli bar + fresh fruit
Eating and drinking during competition
Cyclists should aim to start events well hydrated. Not sufficiently replacing sweat losses can negatively impact cognitive performance and reduced power output. In road races, sipping on fluid regularly throughout the event will help to top up fluid levels. During short criteriums and time-trials, usually no fluids are carried to reduce bike weight so pre-event hydration is particularly important, especially if hot. Water is suitable for short sessions, but in long events or in hot weather, sports drinks helps to simultaneously replace carbohydrate and electrolytes.
The amount of carbohydrate needed during events will depend on the distance and time taken to complete the race. For short high-intensity events, regularly mouth-rinsing with a carbohydrate drink, may provide performance benefits. In longer events (beyond 90 minutes), consuming ~30-60g carbohydrate per hour is recommended to prevent muscle fatigue, maintain power output and cognition. Higher rates of carbohydrate (up to 90g/hour) may provide additional benefit at high speeds and events longer than 3 hours, but this must be a mixture of glucose and fructose and will need to be practiced during training.
A range of foods and liquids can be consumed during races including bananas, energy bars, gels, sports chews, fruit cake/fruit buns, jam sandwiches, dates or sports drinks.
To adapt to the physiological effects of training sessions and competition, recovery is crucial. Recovery meals and snacks should contain carbohydrate (fuel), some protein (for muscle repair and development) and fluids and electrolytes to replace sweat losses. Nutrient rich-choices are more valuable than nutrient-poor choices to meet nutrient goals, reduce inflammation and support immunity.
When energy needs are high and appetite is suppressed or gastrointestinal problems occur following exercise fluids may be preferred (e.g. fruit smoothies, flavoured milk). Other recovery food suggestions include:
- Bircher muesli with nuts and seeds
- Chicken, avocado and salad sandwich
- Burritos with beef, cheese, avocado and salad
Other Nutrition Tips –
- Practice! Fueling strategies should be tested during training to ensure food and fluid can be consumed at speed while moving and/or in a peloton
- Mix & Match Try different food options for different situations – e.g. gels or sports products for races and long rides and everyday food to fuel short to medium length training rides
- Caffeine An Accredited Sports Dietitian can help to be use caffeine strategically to help performance
