Having a watch with an Heart rate (HR) monitor is fantastic until you realise it’s counting 20 BPM too high, and then it’s far less interesting because it’s reporting a moderate workout as heart.

Plenty of heart rate monitors come as chest straps and that’s great if your workout starts and ends somewhere where it’s okay to strap on a heart rate monitor. In winter it’s also about convenience. It is complicated to remove five layers, to put the HR monitor on, and then start an activity.

All climbers are familiar with this. You’re on a climb or a via ferrata and you look up but you don’t see what to do so you feel stuck. As a result you try one hold, and then another, and then a third and eventually you stop. That’s when you remember to look down.

If you look down you see that there is a foot hold 10 to thirty centimetres higher that will give you the extra reach that will allow you to climb onwards. The same is true with tech.
