Cycling FTP: Is 250 Good? Understanding, Interpretation, and Improvement

Is an FTP of 250 good?

An FTP of 250 watts can be considered good, very good, or even average depending on crucial contextual factors such as the rider's body weight, gender, age, cycling discipline, and overall training goals. While a standalone number, it gains significant meaning when expressed as a power-to-weight ratio (watts per kilogram, W/kg).

Understanding Functional Threshold Power (FTP)

Functional Threshold Power (FTP) is a cornerstone metric in cycling performance, representing the highest average power a cyclist can maintain for approximately 40 to 60 minutes, typically measured over a 20-minute maximal effort test (with a small deduction to account for over-threshold effort). It is a critical indicator of aerobic fitness and endurance capacity, serving as the primary benchmark for setting training zones and tracking progress. A higher FTP generally signifies greater endurance potential and faster average speeds over sustained efforts.

Context is King: What Makes an FTP "Good"?

Evaluating whether an FTP of 250 watts is "good" requires moving beyond the raw number and considering several key variables:

• Weight-to-Power Ratio (W/kg): This is arguably the most critical factor. While 250 watts might be impressive for a lightweight climber, it could be less so for a heavier rider. The W/kg ratio dictates how effectively a rider can overcome gravity (especially on climbs) and air resistance.
  • For a 60 kg (132 lbs) rider, 250W is 4.17 W/kg.
  • For a 75 kg (165 lbs) rider, 250W is 3.33 W/kg.
  • For a 90 kg (198 lbs) rider, 250W is 2.78 W/kg. These examples clearly illustrate how the same absolute power output translates to vastly different performance capabilities.
• Rider Category and Experience Level:
  • Beginner: For someone new to structured training, an FTP of 250W is a strong starting point and indicates significant potential.
  • Intermediate: For a regular enthusiast, 250W is a solid, respectable number that allows for strong group rides and competitive amateur events.
  • Advanced/Elite: For highly competitive amateur racers or professionals, 250W would likely be considered low, especially if they are heavier riders. Elite cyclists often have FTPs well over 300W, and even 400W for top professionals, with W/kg ratios exceeding 5.0-6.0 W/kg.
• Cycling Discipline:
  • Climbing: High W/kg is paramount. A lighter rider with 250W (e.g., 4.0+ W/kg) will excel.
  • Time Trialing/Flat Racing: Absolute power (watts) becomes more important, as air resistance is the dominant factor. A heavier rider with 250W might be at a disadvantage against riders with higher absolute power.
  • Mountain Biking/Gravel: A balance of absolute power for bursts and W/kg for technical climbs is beneficial.
• Age and Gender: While individual variation is vast, general trends show that peak power output often occurs between 20-40 years of age, with a gradual decline thereafter. Women typically have lower absolute FTP values than men, but their W/kg ratios can be comparable.
• Training Goals: If the goal is general fitness and enjoying rides, 250W is excellent. If the goal is to win competitive races, the benchmark will be significantly higher.

Interpreting an FTP of 250 Watts

Based on typical power profiling charts (such as those popularized by Dr. Andy Coggan), an FTP of 250 watts can be placed into perspective:

• For a 60 kg (132 lbs) rider (4.17 W/kg): This would typically classify them as a strong amateur or even a Cat 2/3 racer. They would be very competitive on climbs and sustained efforts.
• For a 75 kg (165 lbs) rider (3.33 W/kg): This is a solid intermediate level, allowing for strong group rides and respectable performance in amateur events. They would hold their own on moderate climbs and flats.
• For a 90 kg (198 lbs) rider (2.78 W/kg): This would be considered an average to good recreational cyclist, capable of completing challenging rides but potentially struggling to keep pace with faster groups on sustained climbs.

In essence, 250 watts is a respectable absolute power number for many recreational and even some competitive cyclists. Its "goodness" is entirely dependent on the context of the individual rider and their specific cycling aspirations.

How to Improve Your FTP

If your current FTP is 250 watts and you aim to increase it, a structured approach is essential:

• Structured Training:
  • Sweet Spot Training: Riding at 88-94% of FTP for extended durations (e.g., 2x20 minutes) to build aerobic capacity and muscular endurance.
  • Threshold Intervals: Efforts at 95-105% of FTP (e.g., 3x10 minutes) to directly raise your lactate threshold.
  • VO2 Max Intervals: Shorter, intense efforts above FTP (e.g., 5x3 minutes at 106-120% of FTP) to improve your maximal oxygen uptake and ability to clear lactate.
• Consistency: Regular training, even if it's shorter sessions, is more effective than sporadic long rides.
• Periodization: Structuring your training into phases (base, build, peak) to systematically develop different physiological systems.
• Nutrition and Recovery: Adequate fueling (carbohydrates, protein) and sufficient rest (sleep, recovery rides) are crucial for adaptation and performance gains.
• Strength Training: Incorporating strength exercises, particularly for the lower body and core, can improve power output and prevent injuries.

Beyond the Numbers: The Importance of Practical Application

While FTP is an excellent metric for tracking progress and guiding training, it's vital to remember that cycling performance is not solely defined by a single number. Factors like bike handling skills, tactical awareness, mental fortitude, and the ability to produce power in varying terrain and race situations are equally important. Use your FTP as a tool to improve, but don't let it overshadow the joy and holistic challenge of cycling.

Conclusion and Next Steps

An FTP of 250 watts is a solid foundation for many cyclists, representing a significant level of fitness for the average enthusiast. Whether it's "good" for you depends on your unique physical characteristics and cycling ambitions. To truly evaluate its significance, calculate your power-to-weight ratio (W/kg) and compare it against established benchmarks relevant to your goals. Focus on consistent, structured training, proper nutrition, and adequate recovery to continue improving your FTP and overall cycling performance.
