Five Reasons You Blew Up in Your Race

Racing can be one of the most thrilling yet demanding experiences for any athlete. There’s something electrifying about standing at the starting line, mentally ready to give everything you’ve got. However, even with the best training plans, there are times when races don’t go as planned. If you found yourself bonking, flaming out, or hitting the wall during your last race, here’s a look at five common reasons why things might not have gone the way you envisioned.

Mistake #1: Your Goal Was Unrealistic

Setting ambitious race goals can be a great motivator, but they also need to be rooted in reality. An unrealistic goal, like wanting to run a half marathon under two hours without enough experience at that pace, can lead to disappointment and burnout. Rather than setting a goal based on an idealized time, start with what pace feels sustainable. Look at recent training or race data to determine what you’re capable of at that moment and then plan your race day goal accordingly. This approach ensures you’re prepared both mentally and physically, leading to a more enjoyable race experience.

Mistake #2: Your Goal Was Realistic, But You Went Out Too Fast

The excitement of race day can make it difficult to control your pacing, especially at the start. Often, runners are tempted to “bank time” by running faster in the early stages, hoping to offset the slower miles later. However, going out too fast can deplete your glycogen stores more quickly and cause you to accumulate fatigue prematurely. This is especially true for races lasting over an hour, where energy management is key. Instead, try starting a little slower than your goal pace, allowing yourself to ease into the race. As you settle in, you can gradually pick up speed, but don’t try to gain time in the first few miles. Trust that a steady, controlled pace will ultimately get you across the finish line faster and in better shape.

Mistake #3: You Didn’t Adjust for the Conditions

Every race brings its own unique conditions, and failing to adapt can derail even the best-laid plans. If your training took place on flat terrain, but the race course is hilly, or if you trained in cooler months only to race in hot, humid conditions, these factors can significantly impact your performance. Hills require additional strength and pacing adjustments, and heat can lead to faster dehydration and fatigue. When faced with unfavorable race-day conditions, modify your goals accordingly. This might mean slowing down, hydrating more frequently, or being more mindful of your pacing. By adapting your strategy to the elements, you’ll conserve energy and avoid the unpleasant effects of overexertion.

Mistake #4: You Got Dehydrated

Proper hydration is critical in endurance racing, especially for events lasting over an hour. Even mild dehydration (a 2-3% loss in body weight) can reduce your performance by as much as 6%, while more severe dehydration can lead to declines of up to 30%. Understanding your body’s hydration needs—especially for longer races in warm or humid weather—can prevent this. For races lasting several hours, consider not only water but also electrolytes, which are vital for maintaining muscle function and preventing cramping. Dehydration can also lead to gastrointestinal distress, which can further impair your ability to fuel properly. A well-calibrated hydration plan that includes regular intake of fluids and electrolytes will help you stay strong and focused throughout the race.

Mistake #5: You Ran Out of Glycogen

The infamous “wall” that many runners hit, particularly in longer races, is often caused by glycogen depletion. Glycogen is your body’s primary fuel source, especially during intense or prolonged efforts, and when it runs out, performance drops sharply. Insufficient fueling and overly ambitious pacing are the primary causes of glycogen depletion. For races lasting over 2.5 hours, aim for a carbohydrate intake of 60-90 grams per hour to keep your energy levels stable. In shorter races (up to 2.5 hours), 30-60 grams per hour is generally sufficient. Consider practicing your fueling strategy during training runs to find what works best for your body, as this will also help minimize any potential GI issues on race day.

Putting It All Together

Successfully finishing a race without burning out involves finding a balance among all these factors. Choosing a realistic goal, pacing yourself appropriately, adapting to conditions, staying hydrated, and fueling well can prevent you from “blowing up” and ensure a more satisfying race experience. Remember, each race is an opportunity to learn and fine-tune your approach. With the right adjustments and preparation, you can make your next race a stronger, more enjoyable experience.
