New R script: Plot Nike+ runs

June 5th, 2009

I’ve been playing around with R and Nike+ and thought I’d put the two together, so I wrote a little R script that pulls your public data from the Nike+ website and plot out the graphs. It’s a little rough around the edges (see below for a list of enhancements/fixes), but it generates plots. I like SlowGeek, but found their smoothing function a bit too “smooth” — it was shaving 1/2 mph from my run speeds. I wasn’t happy with that 😉 Read more to get the source code, below.

For an example of what it might look like, you can see my plots.

My running history via slowgeek.com

balinjdl running history (slowgeek.com)

I recently found a post on the Nike+ forums that describes how to get the running history (in detail). It also shows how to access the data via slowgeek.com, a very slick adventure indeed!

P.S. I was going to set up a running blog, but don’t know if I will now. Slowgeek.com gives me the data I was looking for, though I’m still itching to learn and use OpenFlashCharts!
