How to Run a Marathon

Run the Tangents

Most people think the marathon is exactly 26.2 miles. This is true, but only if you run the shortest legal route possible. Each course is measured on its shortest possible route, called the route line. The goal is to stay as close to the tangents as possible. The only time you ever want to be off the route line is to get water, avoid traffic, run in the shade on a hot day, or run on a surface that is superior to the tangent. However, most people aren’t aware of the route line and end up running much further. These runners can add enough extra distance to affect their time adversely. By running the course correctly, it is possible to knock anywhere from 3 to 5 minutes or more off your time.


Let’s take the New York City marathon, for example. Once runners enter Central Park, there are 46 turns. If they are not running the tangents, they can be adding at least two to three seconds per turn. For just this portion of the race, one can add as much 2-3 minutes depend on your pace! Runners tend to stay on or near the centerline for the entire race. Even on a 90-degree turn where the inside curb was 30 feet away, they tend stay on this line. Do not do this, it adds time! Over the course of a marathon, you are adding more than a few minutes to your overall time.


Obviously, many people figure it doesn't matter all that much. The math, however, will show different results. After the L.A. race, there were complaints on the bulletin boards stating the course was too long. Instead of the 26.2 miles, some runners who brought their fancy high-tech GPS had readings of 26.55-27. This meant these runners ran an extra 1/3 of a mile because they did not run the tangents. In my estimation, a bulk of the runners will run an extra 0.3-0.5 miles over the course of a normal marathon. This means a runner who averages 10 minutes/mile will run an extra three minutes and 30 seconds to an extra five minutes because of the extra distance. You do not want to be one of those runners who needlessly adds five minutes to your time.

Here is a map that shows the first mile of the LA marathon from several years ago. The course is measured from the exact inside line. The width of the road was about 80-100 feet wide. Running an average 60 feet from the inside line for the entire mile, would cause one to run an extra 376 feet. For a person running a ten minute mile, this shows they would run and extra 42 seconds just in the first mile.

This picture shows runners going up Temple Street in the L.A. marathon. At the bottom of the hill, the runners made a right turn onto this street. At the top of the hill, the runners made another right turn. This street is about 80 feet wide. This means the people on the right of this picture ran an extra 160 feet just in those few short blocks. If they were running 10 minute mile pace, they added 18 seconds to their time. The ideal line is to stay as close to the right curb as possible.

With the above examples, it is easy to see how one could lose ten to twenty seconds here and there. These seconds soon add up to minutes.

The goal is to take the same line that the course is measured on. This requires focus on your part. Plot your heading after coming out of each corner. Aim for the apex of the next curve.


Remember the analogy. You want to see your self as a race car driver trying to take the inside line on every turn.
