Jan. 16, 2015
A new year, and a new version… You can now send your runs directly into Strava, RunKeeper, and MapMyRun!

I'm a huge fan of Nike+. Recently, however, I've been having some trouble - the iPhone app crashes a little too frequently, a few of my runs wouldn't upload, and my stats don't look quite right.
So, inspired by EagerFeet, I decided to see if I could create a little utility to download my run data from Nike+, so that I could try out some of the other GPS-based run trackers like RunKeeper or Strava.
After a bit of trial and error, I was able to extract all of my runs, including GPS and heartrate data, and save them as GPX-formatted files that can be imported into most of the other sites.
A few important disclaimers…
- I've built this app without the blessing of Nike+, so I have no idea how long they'll allow it to work.
- Since Nike+ doesn't provide an export feature, I had to make a few guesses about how to interpret the data. I've double-checked the output for all of my runs, and it looks pretty good. But I can't guarantee that this will work for everyone. In particular, I'm not sure how well I've handled runs with long pauses.
- Since I'm not a certified Nike+ “partner”, I'm not able to use Nike's official OAuth system to connect to its site. So for now, my app requires that you enter your Nike+ credentials. I can promise you that I don't store that info - I only use it to allow my server to log into Nike+ on your behalf, so that it can request your data. Of course - I recognize that for some (or many) of you - this is a dealbreaker. But if you're willing to trust that I will not save or misuse your credentials in any way whatsoever, then you can try this out.
If the download works, the app will prompt you to save a .zip file containing a series of GPX-formatted files, one for each of the runs you select. Or, you can send your runs directly to Strava, RunKeeper, or MapMyRun, without having to download them first.
Good luck, and happy running!
