HRM in a race
I have a polar 625x and I'm doing a sprint on Sun.
1) Has anyone tried to use a multisport during a race?
2) How do you switch modes, i.e. from cycling to running? Mine does not seem to have a way to keep the same workout but use different modes.
3) Or do you set it for HR and leave it at that?
4) Do you wear it for the swim?
