Here are some other websites with APIs that would probably let me embed workouts and other data, let me know if you would find some or all of these useful:
- RunKeeper
- TrainingPeaks
- MapMyRun/MapMyFitness/etc (UnderArmour)
- Movescount
Unfortunately these websites do not currently offer an API, or charge for API access:
- TrainerRoad
- Garmin Connect
I'll update this list as things progress.
