Marathon Benchmarks for Women in Their 40s

Women racing marathons in their 40s are in a competitive and growing segment of road racing. Many women achieve their best age-adjusted marathon scores in this decade — discipline, patience, and training maturity produce results that raw aerobic capacity alone cannot.

Quick answer: For women age 40–49 running the Marathon, a 60% age-grade (“Local Class”) at age 40 is 3:43:43. A 70% Regional Class performance is 3:11:46, requiring easy pace 8:30/mi, threshold 6:49/mi. These benchmarks are from WMA (World Masters Athletics) 2025 standards.

What each level means

  • National Class (80–89%) — Competitive at national masters championships. Requires serious, structured training over years.
  • Regional Class (70–79%) — Strong age-group placements at regional races. Consistent training with quality sessions.
  • Local Class (60–69%) — Competitive in local races. Solid fitness from regular running and some structured training.
  • Recreational (below 60%) — Running for fitness and enjoyment. Most runners start here.

Training paces by performance level

The training paces below are derived from each WMA benchmark time. If you are running at 70% age-grade, these are the training zones that produce and maintain that performance level.

Training at this age and distance

Marathon training for women in their 40s requires one threshold session per week, long runs to 18–20 miles, and adequate recovery between quality sessions (5–6 days). Easy days at genuinely easy pace allow both the threshold session and the long run to generate full adaptation. This decade rewards training intelligence over training volume.

Calculate your exact age-graded score

Enter your race time below to see your precise WMA age-graded percentage and where you fall relative to these benchmarks.

Age-Grading: Calculates your performance as a percentage of the World Record standard for your specific age and gender. This creates a unified 'Level Playing Field' across all demographics. An 80% score at age 60 represents the exact same relative competitiveness as an 80% score at age 25, even though the absolute race times differ.

Population benchmarks are starting points

WMA age-grading tells you how your time compares to world-record standards for your age group. StrideIQ goes further — it tracks your individual efficiency trends, recovery patterns, and adaptation curves from your actual training data. At any age, knowing your population percentile is the beginning. Understanding your personal response to training is what drives real improvement.

Common questions

What is a good Marathon time for women in their 40s?

Using WMA age-grading standards, a 40-year-old woman running 3:43:43 scores 60% ("Local Class"). A 70% "Regional Class" performance at that age is 3:11:46. These benchmarks are derived from world-record data for each age group, not population averages.

What training paces should women in their 40s use for Marathon training?

The right training paces depend on your current fitness. At 70% age-grade (3:11:46 for a 40-year-old), your training zones are: Easy 8:30/mi, Threshold 6:49/mi, Interval 5:58/mi. At 60% age-grade (3:43:43): Easy 9:40/mi, Threshold 7:38/mi. Use the calculator below to find your exact paces.

How does Marathon performance change through the 40s?

WMA data shows a gradual performance decline with each decade — typically two to five percent per five years for most distances. The age factors in the table above account for this and allow fair comparison across ages. Consistent training often offsets age-related decline significantly. Many runners in their 40s who train with structure outperform their unstructured earlier years on an age-adjusted basis.
