Nike Update: we are aware that quite a few Nike+ users are having some trouble importing their runs to Smashrun today. Last night, Nike implemented some changes to their site that is now affecting the way we import run data. We are looking into it and will try and push out a fix as soon as possible. We sincerely apologize for the inconvenience.
Update (2.17.12): Spent all of yesterday pinpointing the issue that came up with the Nike import and pretty much figured out what the problem was. We should be able to release a fix by this evening. Happy Friday!
Update (2.18.12): Fixed! Please try importing your Nike+ runs and let us know if you find anything unusual.
