I was using Strava with bluetooth hrm strap. Only things close were car key (53 plate), mini compass, whistle, and Trek bar.
Location & Bluetooth enabled. I had left 4g on but have done this lots of times before with minimal data used. Fwiw: I find switching 4g on helps phone find gps quicker, I usually turn it off once it has located me tho.
