10 years of marathons
An analysis of all the marathons I’ve done in the last 10 years.

An analysis of all the marathons I’ve done in the last 10 years.
I’ve done dozens of races and about 15 marathons since I started running. I’ve plotted my pace for 15 official marathons. Its quite obvious now that I’ve plateaued at a nominal pace. You can see that I got fast quite quickly - after about three years I hit my plateau of about 8 minutes per mile.
In my first three years of running I ran about 20 miles a week - sometimes more, sometimes less. I started running fast and a year of intense training about five years in, which got the lowest dot on that graph - a sub 7 minute per mile marathon (which qualified me for the Boston marathon).
I also computed my relative placement in marathons to see how I did compared to others. The relative placement is my place overall divided by the number of people in the race. A relative placement of 1 means that I finished last, and 0.5 means I finished right in the middle.
You can see that over those first three years my relative placement plunged a lot more than my pace. This shows that you can do a lot better in a race by just increasing your pace a little bit. Currently I’m able to hover around the top 15% of any given race.
I think this is a nice illustration of being able to work for something you want. I wanted to become a marathon runner, so I ran. I started out bad (finishing in the last 20% of the my first marathon) but over three years you can see I gradually improved. You can also see that those improvements have lasted over the years, as I continue to run casually.
