Data Visualization
The reason I created the following visuals was because I had all of this data from when I ran my marathon in December of 2015. It's interesting to compare myself to those that I competed against, and especially one of my good friends, Matthew :)
I came across the idea to do this from one of the Viz of the Day on Tableau. However, I thought that it would be interesting to see my progression over time from when I first started training up until the day of the marathon. My totally unserious thought was, if you follow my regimen, you too can run a marathon within 3 and a half months.
Back to the data. Because I had used the Nike+ app for my runs, I still had all of the data during that time period. This allowed me to do a time/plot series to show my progression over that time period.
