Polar HR M400 is a very good product , but does not not allow to register in sequence the 3 sports in an Ironman. Yo need to start using it in Swim mode, then you need to pause it , end the activity track , select bike , start, and at the end of the bike repeat the proccess of pausing, ending, and selecting the Run, and again...
But... is there any way you have used the Polar M400 to register your participation in Ironman in another , more easy way ?
Best wishes
