During a gran fondo, conditions on the course rarely remain the same between start and finish. A cool morning can give way to a milder day, a long climb can be followed by a fast descent, while a headwind or rain can completely transform the feeling on the bike. In these conditions, choosing your cycling kit is an integral part of preparation, just like training or bike setup.
Experienced cyclists anticipate conditions throughout the course. They check weather forecasts, study the route profile, and choose their equipment to remain comfortable throughout the ride.
With the experts from Routes and Roads, let's look at what kit to prioritize for a road race or gran fondo, how to choose each item of your equipment, and what criteria to consider before making your choice.

Principles for Choosing Your Cycling Kit Well
Start by studying the weather forecasts and the course characteristics. The duration of the event, elevation gain, wind-exposed sections, and risk of rain directly influence equipment choice. By anticipating changing conditions throughout the course, it becomes much easier to choose suitable apparel.
For example, in spring, a race in the Paris region might start at 8°C, before the temperature reaches 18°C a few hours later. To easily adapt to these variations, the three-layer principle remains the best solution. An effective outfit relies on a base layer, a thermal layer, and a protective layer. The base layer wicks away perspiration, the thermal layer provides necessary warmth, while the outer layer—gilet, windbreaker, or rain jacket—protects against wind and bad weather. This system keeps you comfortable throughout the race.
The three-layer principle allows adaptation to all weather conditions.
Base Layer and Cycling Jersey
The base layer and jersey are the core of a cyclist's kit. They are worn from start to finish, while other elements can be added or removed depending on the weather and course profile.
The Base Layer
During sustained effort, clothes gradually become damp. If this moisture remains in contact with the skin, a sensation of cold appears from the first long descent. The main function of the base layer is therefore to quickly wick away perspiration. A quality base layer efficiently transfers moisture to the outer layers, which allows the skin to stay dry longer and mitigate the effects of temperature variations. This difference is particularly noticeable over long distances, where sustained climbs constantly alternate with fast descents.
The choice of base layer primarily depends on the weather. In summer, opt for a light, short-sleeved synthetic model, capable of quickly wicking away perspiration while limiting overheating. For mid-season, long-sleeved models are more comfortable, and in cool weather, models containing merino wool are an excellent option: they retain their insulating properties even when damp, which limits sensations related to temperature fluctuations. On the other hand, it is best to avoid cotton t-shirts for a race. They quickly absorb perspiration, dry slowly, and cool the body on fast descents.

How to choose your cycling jersey
During an event, the jersey wicks moisture outwards, protects the skin from sun and wind, while its rear pockets allow for easy transport of nutrition, phone, gilet, or rain jacket.
When choosing, pay particular attention to the fit. The jersey should be snug without restricting movement when you are in position on the bike. A cut that is too loose compromises aerodynamics, and fabric folds can cause irritation over many kilometers.
The rear pockets are just as important. During a long event, they typically hold energy gels, a phone, a multi-tool, a gilet, or a rain jacket. Before the race, it is advisable to go for a multi-hour ride with the pockets fully loaded. This way, you can check that it's easy to access their contents while riding and that the extra weight does not affect the jersey's hold.
Wind and Weather Protection
The Gilet
For the majority of gran fondos organized in spring, summer, or early autumn, the gilet remains the most versatile outer layer. It protects the body from wind while maintaining good ventilation in the back and easily stores in a jersey pocket once folded.
The gilet is particularly useful on long descents or exposed sections, where the relative wind quickly cools the body. As soon as the road goes uphill or the temperature rises, simply remove it and slip it into a pocket.
When choosing a gilet, opt for a model whose front offers good wind protection and whose back promotes heat and moisture wicking. This combination allows you to stay cool and comfortable despite changing conditions, without risk of overheating during effort.

The Windbreaker
If the weather remains cool for a large part of the event, a simple gilet may not be enough. A windbreaker also protects the arms and retains more warmth on long, fast descents, for example, early in the morning or when the wind is blowing strongly.
Modern cycling windbreakers are very light and can be easily stored in a jersey pocket. For racing, choose an anatomically cut model, close to the body, to prevent the fabric from flapping or wrinkling while you ride.
The Membrane Jacket
If the forecast announces dry weather or only a few showers, a windbreaker or gilet is usually sufficient. However, when prolonged rain is predicted, a waterproof membrane jacket becomes the most reliable solution.
Unlike a simple windbreaker, it is designed for long rides in the rain. Its membrane prevents water from penetrating while allowing water vapor produced during exertion to escape. This keeps the clothes worn underneath dry longer, which significantly reduces the risk of getting cold.
For racing, choose a lightweight model that folds down to fit in a jersey pocket. A cycling-specific cut, with an elongated back and sleeves adapted to the riding position, ensures comfortable pedaling without hindering movement.
If rain is forecast, plan for a membrane jacket
The Thermal Jacket
If the event takes place in early spring, late autumn, or at temperatures close to 0°C, a simple outer layer is no longer sufficient. In these conditions, a thermal cycling jacket is a more suitable solution, combining wind protection, effective insulation, and good moisture wicking.
These jackets are designed to support prolonged effort and differ from classic winter jackets. They fit the body, offer great freedom of movement, and remain comfortable even during intensive pedaling. Before the race, take the time to test your jacket during a long ride in similar conditions: this is the best way to verify that it suits your pace and the expected conditions.
Bib Shorts and Leg Protection
The Bib Shorts. How to choose your bib shorts
Among all cycling apparel, bib shorts are undoubtedly the item that most influences comfort during a long ride. While a jersey or gilet can be removed if necessary, bib shorts accompany you from start to finish. A poor choice often goes unnoticed at first, but after several hours in the saddle, it can distract you from the road and disrupt your rhythm.
The fundamental element of bib shorts is the chamois pad. This insert reduces pressure at contact points with the saddle, limits friction, and significantly improves comfort over long distances. When choosing, it's better to focus on its shape, density, and material quality rather than its thickness. A good chamois retains its elasticity under pressure and naturally follows the cyclist's movements while pedaling. This better distributes pressure and significantly reduces the risk of irritation.
Bib shorts are one of the elements that most influence comfort on the bike
The cut of the bib shorts is just as important. They must fit the body perfectly, stay in place while pedaling, and not form any creases. For road races, most cyclists choose bib shorts with straps. These perfectly hold the bib shorts, keep the chamois pad in the correct position, and avoid the pressure of an elastic waistband, which is particularly noticeable in an aerodynamic position.
Before the race, always take the time to test your bib shorts on one of your longest rides. After several hours in the saddle, you will be able to assess their support, the effectiveness of the chamois, and verify that they remain comfortable throughout the distance.
Gloves, Socks, and Shoe Covers
Cycling Gloves
During a long ride, hands constantly absorb road vibrations. These are barely noticeable on smooth asphalt but become much more pronounced on rough surfaces, cobblestones, or gravel paths. Good cycling gloves reduce pressure on the palms, improve grip on the handlebars, and enhance bike control.
For summer gran fondos, short and well-ventilated models are generally chosen. In spring and autumn, long gloves are more comfortable: they protect the hands from the wind and help maintain good finger sensitivity in cool weather. When hands start to get cold, it becomes more difficult to effectively use the brakes and shift gears, which can impair bike control.
When trying them on, make sure the gloves fit snugly, don't wrinkle, and don't restrict finger movement. They should remain comfortable regardless of hand position on the handlebars.

Socks
Cycling socks are just as important as bib shorts or shoes. They must fit the foot perfectly, wick away moisture quickly, and stay firmly in place while pedaling. In hot weather, opt for lightweight technical models, and in cool weather, choose models with merino wool that offer better insulation, even when damp. Cotton socks, overly loose models, or pairs with thick seams risk causing blisters after only a few hours in the saddle.
Sock height generally depends on personal preference or the regulations of certain competitions. The main thing is that they are well-fitting, dry quickly, and stay perfectly in place while pedaling.

Shoe Covers
In cold or rainy weather, feet are often the first to get cold. The wind quickly cools cycling shoes, and once wet, they rarely have time to dry before the finish line.
Shoe covers protect shoes from wind and splashes, helping feet stay warm longer. In cool, dry weather, a windproof model is usually sufficient. If heavy rain is forecast, choose shoe covers made from waterproof materials with sealed seams.
Conclusion
A well-chosen cycling kit allows you to fully concentrate on your pace, strategy, and the road, without being distracted by heat, cold, damp clothing, or saddle discomfort.
