How to save time and distance in races by understanding tangents.
Are you Adding Unnecessary Distance (and Time) to your Races?
Ever crossed the finish line of a marathon only to realize your watch reads 26.6 miles instead of 26.2? That extra 0.4 miles might not look like much on paper, but on race day, it can mean minutes tacked onto your time. And if you’re chasing a personal best—or even a Boston-qualifying standard—every second counts.
GPS errors aside, that extra distance often comes down to not running the most efficient line. Maybe you’ve heard the phrase “run the tangents” but didn’t know exactly what it meant: read on, you’re about to learn!
What Does it Mean to Run the Tangents?
Running the tangents simply means following the shortest possible path around a course, especially when it curves or turns. It’s all about minimizing unnecessary distance by taking the most direct line from Point A to Point B, such as the start line to the finish line of a race.
While it sounds simple, it’s something many runners overlook in the excitement of race day—and it can cost them.
Courses are measured along the shortest possible route. That means weaving wide around corners adds distance—just like running around the outside of a track lane instead of staying in lane one.
Think of a road that curves to the left. If you stay on the outside edge of the bend, you’re running farther than someone hugging the inside. Multiply that by dozens of turns over the length of a half or full marathon, and you might run an extra quarter to half of a mile. That’s free distance—and time—you’re giving away.
How to Run the Tangents
Running the tangents doesn’t mean cutting corners or breaking course rules. It means staying mindful and strategic as you move through the course from the start to finish. And for those wondering, it is a perfectly acceptable strategy that the pros harness in every race, and you should too!
Here are a few ways to improve:
In training:
- Practice running efficient lines. On your long runs or routes with curves, get used to spotting and running the straightest line possible. Make it second nature.
Before the race:
- Study the course map. Identify turns, loops, or sections where you might need to adjust your line.
On race day:
- Look ahead. Don’t just react to a curve once you’re in it. Keep your eyes forward so you can anticipate and run the cleanest line.
- Avoid drifting with the pack. Runners often spread out and take wide turns—don’t blindly follow.
Go Faster, not Further!
The good news is that running the tangents doesn’t require more fitness or effort—just a little awareness. And that bit of additional awareness can be the difference between almost hitting your goal and crushing it.
