Let’s get a little nerdy, but keep it breezy. For men, the average finish time is typically around 4 hours and 10 minutes. That’s a solid pace of about 9:30 per mile.
For women, the average tends to clock in closer to 4 hours and 45 minutes. That’s about a 10:50 per mile pace. Why the difference? Blame biology, not effort. Women generally have a higher body fat percentage (which is great for survival, less great for speed) and slightly less muscle mass.
But here’s the funny thing: women are often better at pacing. They start smarter, don’t burn out as fast, and have a legendary ability to push through pain. So, while the average is slower, the "grit average" is off the charts.
Age: The Invisible Handbrake (That Gets Gentle Over Time)
Your age is like a mischievous gremlin in the marathon engine. The sweet spot for speed? Typically your 30s. That’s when you’ve got the fitness of youth and the brain of an adult who actually stretches.
In your 40s, you’re still a beast. The average time slips to about 4:20 to 4:30. In your 50s? You’re looking at 4:40 to 5:00. And if you’re over 60? You are an absolute legend—the average is around 5:20, but honestly, you’re lapping everyone on the couch.
The real kicker? Most runners slow down by about 3-5% per decade after age 30. That’s a bummer, but think of it this way: you get 10% more permission to eat celebratory pizza afterwards.
