Endurance athletes push their limits daily, whether running marathons or walking long distances. The ability to sustain energy and maintain stamina is crucial in both sports. Some believe anabolic steroids can provide an edge by boosting endurance, but do they actually work for long-distance runners and walkers? More importantly, what are the risks?
Do Steroids Improve Endurance?
Steroids are commonly associated with muscle growth and strength, but their effects on endurance are less straightforward. Some athletes turn to performance-enhancing substances, such as those found through steroids Canada, hoping to improve stamina and overall performance. However, while anabolic steroids can increase red blood cell production, they do not necessarily enhance aerobic capacity the way endurance athletes require.
Anabolic steroids primarily work by increasing protein synthesis and muscle recovery, which may benefit sprinters or strength-based athletes. For endurance sports like marathon running or long-distance walking, the body’s ability to use oxygen efficiently (VO2 max) and maintain steady cardiovascular performance is more critical than just muscle strength.
The Science Behind Steroids and Endurance
Research on the effects of steroids on endurance performance is mixed. Some studies suggest that steroids may boost recovery time, allowing runners and walkers to train harder and recover faster. However, they do not directly improve cardiovascular endurance. In fact, some anabolic steroids may negatively impact endurance by increasing body mass, which can make running or walking long distances more difficult.
On the other hand, substances like erythropoietin (EPO) or blood doping have a more direct effect on endurance by increasing red blood cell count and oxygen delivery. This is why EPO is more commonly associated with endurance sports, while steroids remain more popular among strength-focused athletes.
Risks and Side Effects
While some athletes may see temporary benefits from steroids, the long-term risks outweigh any short-term gains. The side effects can be severe and include:
- Increased risk of heart disease
- High blood pressure
- Liver damage
- Hormonal imbalances
- Psychological effects like aggression and mood swings
For endurance athletes, an additional concern is the impact on tendons and ligaments. Steroids can promote rapid muscle growth, but if connective tissues do not strengthen at the same rate, it increases the risk of injuries like tendon ruptures. A torn ligament or tendon can sideline a runner or walker for months, ultimately defeating the purpose of using performance enhancers.
Expert Opinions on Performance Enhancement
Dr. James Anderson, a sports medicine expert, emphasizes that endurance sports rely more on efficient energy use than muscle power. “Steroids can help with muscle recovery and strength, but they don’t directly enhance oxygen utilization or endurance. Athletes who rely on stamina and cardiovascular health won’t benefit as much as they think,” he explains.
Olympic coach Sarah Mitchell adds, “The best way to improve endurance is through proper training, nutrition, and rest. Shortcuts like steroids often come with consequences that outweigh their benefits.”
Alternative Ways to Boost Endurance
Instead of relying on anabolic steroids, athletes can improve their endurance naturally by focusing on key areas such as:
1. Training Strategies
- Interval training to boost cardiovascular performance
- Long-distance training at moderate intensity to build stamina
- Strength training to support joint stability and prevent injuries
2. Nutrition and Hydration
- Eating a balanced diet rich in complex carbohydrates, lean protein, and healthy fats
- Staying hydrated to maintain optimal muscle function
- Supplementing with natural endurance boosters like beetroot juice, caffeine, and BCAAs
3. Recovery and Rest
- Prioritizing sleep for muscle repair and overall recovery
- Using techniques like stretching, massage, and ice baths to prevent injuries

Final Verdict: Are Steroids Worth the Risk?
For strength-based sports, steroids can provide a competitive edge by increasing muscle mass and recovery speed. However, for endurance athletes, the drawbacks far outweigh the benefits. Running and walking require sustained energy output, efficient oxygen use, and cardiovascular strength—factors that steroids do not significantly improve.
Instead of taking risks with performance-enhancing drugs, endurance athletes are better off optimizing their training, diet, and recovery techniques. The road to success in running and walking is built on discipline, smart training, and patience, not shortcuts with dangerous side effects.
