For Fun: Half Marathon

View larger

On Sunday I ran my first half marathon at the Alexandria Running Festival. It was a beautiful, cool, sunny morning, and I managed a time of 2:04:18. I've never been a running superstar, so I was really pleased. A big thanks to all of the event organizers and volunteers for putting on a great race and keeping the energy up on the course.

As race day approached, I was struck by just how small a component of running a half marathon the actual race is. Don't get me wrong — running 13.1 miles is daunting, particularly for someone who hasn't raced in a few years. But the vast majority of the hard work, stress, anticipation and strategy come weeks and months earlier.

The chart above shows the full half marathon: the 13.1 miles I ran on Sunday plus the 12 weeks of training that made the final 13.1 possible. I liked the idea of arranging the data in a circle rather than a linear time-series chart, mostly because training process is very cyclical. Each week has a pattern of long, short and mid-distance runs, and once the final race is finished it's time to start gearing up for the next challenge (for me, it's the Marine Corps Marathon's Run Amuck on June 8). Plus, I thought the circle would look cool.

To create this chart in Illustrator, I first made two standard column charts using the Chart feature, one each for the distance and pace-per-mile data. Then I copied the individual columns onto a grid of circular "spokes" that I drew manually (if there's a way to have Illustrator generate a grid like this, I'd love to learn it!). The concentric rings showing the mile scale for the distance data and the minute scale for the time data were drawn to fit the columns, rather than the other way around. Overlapping the distance and time columns meant I overlapped the scales as well. It's a little crowded there at the center of the chart, but I hope it works.
