5 Mistakes to Avoid Before a Granfondo: A Practical Guide for Cyclists

The Granfondo is the moment of truth for every cyclist: months of training, sacrifices, and anticipation concentrated into one epic day. However, pre-race excitement can play tricks on you, turning a day of pure pleasure into a physical and mental ordeal. As an industry tester and analyst, I have seen too many athletes compromise their performance even before the starting gun fires. Here are 5 massive mistakes you must avoid to arrive at the finish line in the best possible condition.
1. Experimenting on Race Day
The classic mistake: testing a new product (be it an energy gel, a bar, a pair of socks, or even a bike component) on the day of the Granfondo.
Why avoid it: Your digestive system and muscles are used to established routines. An untried supplement can cause immediate gastric distress, while a new pair of shoes can create pressure points or blisters that make pedaling unbearable.
The golden rule: In a race, use only what has been thoroughly tested during long training rides.
2. Ignoring Glycogen Loading (and Hydration)
Arriving at the start line without having managed your nutrition in the two days prior is an unforgivable own goal. Likewise, overloading on food the very morning of the race, just a few hours before the start, is just as severe a mistake.
Why avoid it: Poorly managed carbohydrate loading weighs down the digestive system, leading to insulin spikes followed by glycemic crashes right during the first climb. Furthermore, hydration cannot be recovered by drinking liters of water 10 minutes before the start: dehydration is a slow process that must be prevented consistently in the 48 hours preceding the event.
3. Neglecting Last-Minute Mechanical Checks
Relying on superstition instead of a torque wrench is an unnecessary risk. Checking your bike on the morning of the race, amidst the confusion of the starting grid, is a source of stress and increases the likelihood of making errors in judgment.
Why avoid it: A dry chain, tire pressure not suited to the day's weather conditions, or poorly adjusted gearing can turn a Granfondo into a day of mechanical frustration.
Technical secret: Perform a full check-up 2–3 days before. On the morning of the race, limit yourself to checking tire pressure, electronic shifting battery status, and brake integrity.
4. Going "All-Out" to Keep Pace with the Leaders
The adrenaline on the starting grid is powerful. Seeing the peloton pull away at high speeds pushes many to forget their own ideal pacing.
Why avoid it: Going into the red in the first few kilometers means accumulating lactic acid prematurely, compromising your ability to manage long climbs or the final kilometers of the race, where positions are usually decided.
Pro tip: Stick to your threshold. A Granfondo is a marathon, not a 10km sprint.
5. Not Having a Backup Plan (Plan B)
Many cyclists start with a single, rigid goal, ignoring external variables like the weather, a crash in the group, or a "bonk" (hitting the wall).
Why avoid it: A lack of mental flexibility leads to a loss of focus and demotivation. If the weather suddenly worsens and you haven't prepared appropriate clothing, or if you lose your reference group, it is essential to know how to recalibrate your goal (e.g., transforming the race into a high-quality long training ride).
The strategy: Always prepare two clothing options and study the elevation profile to identify critical points where you need to manage your energy.
Summary Table: Pre-Race Checklist
Equipment Testing: Everything tested in training.
Nutrition: Gradual glycogen loading (not just breakfast).
Mechanics: Check-up 72 hours before the start.
Pacing: Manage your threshold, not the group.
Mindset: Be ready to manage the unexpected.
Editor's note: Mental preparation is just as important as physical preparation. Respect your current condition and enjoy the experience.
