Simultaneous Bluetooth Smart Heartrate Monitor and Bluetooth Smart Footpod?

[Pseudo-Fed]

Want to use a running app either indoors or outdoors with bluetooth smart heartrate monitor such as the Mio Alpha AND a bluetooth foodpod (for treadmills indoors or cadence outdoors) such as the Adidas Speedcell. I read my iPhone 5 will pair with several but will only be actively connected to one device at a time. Anyone know if I can connect both?
