So I’m sat here this evening, feeling a bit sorry for myself, with the cold symptoms just under the surface. Then I remembered the problems I get with the watch and its HR sensor. I then remembered I had some Christmas pennies in Amazon. So I’ve gone and got me one of these.

It’s a heart rate monitor that links to the watch using the ANT+ wireless comms link. The watch can use that instead of its less reliable on-board sensor. Turns up on Tuesday.
