While the Adidas Train app is available on Fitbit Ionic Adidas edition, feel free to post your idea in our Feature Suggestions board.

I also use this app often (it used to be Runtastaic). Compared to Strava it does a lot more feedback during the activity as long as you are tracking it. Would be really good to be able to integrate fitbit and runtastic/Adidas running for tracking of walking and other activities.
I would also like to sync my Ionic Fitbit Adidas edition you the Adidas run app. Don’t understand why Fitbit is not a partner app but sells Adidas edition. I want to earn points for my running shoes with Adidas.
The way that I do it is to download the activity file (tcx format) from the Fitbit Dashboard and upload it to Runtastic via the Website.. this should also count within the app, the km I track and upload that way count for all challenges and the adidas running activities.
Unfortunately this is a problem with Adidas (former Runtastic) and the request should be asked to Adidas. In fact while Fitbit offers an API to send data to other services there is no API from Adidas to receive data from outside. The matter therefore should be solved by Adidas. It is also true that Fitbit could contact Adidas to facilitate the communicatiob between the two services.
For completeteness the solution proposed by @Lipu above can not be used any longer since the possiblity to import TCX via browser is no longer supported.
