You can run a marathon after 40. That’s not motivational filler — it’s a physiological fact. The masters runners who flame out aren’t victims of age; they’re victims of a training plan written for a 28-year-old that they refused to modify. Adjust the inputs and the outcome holds.
But adjustments are required. Your cardiovascular engine still responds to aerobic training. Your VO2 max still improves. Your legs will still carry you 26.2 miles. What changes is the rate at which your body rebuilds between sessions — and if you don’t account for that, the plan that works for younger runners will gradually grind you down.
Here’s what the evidence actually says, and what to do about it.

The last weekend of July delivered one of the year’s most varied stretches of marathon racing: a 7,000-person road spectacle threading through San Francisco’s hills, a handful of altitude-battered trail efforts in the mountain West, and a brace of small-town events that reminded you why runners travel for this.

Most runners chasing a Boston Qualifier have been conditioned to think canyons, net downhill, and 4 a.m. bus rides. The formula is familiar: get dropped in a mountain hollow, grind down a canyon, and pray the second half cooperates. The Cytiva Top of Utah Marathon, in its 28th year, offers a different theory — and if your fitness is honest, you’re going to like what it says.
Thanks for reading 🤍
