Just been given a Timex Ironman HRM (ladies version - ie small watch). Previously had a Ciclosport HRM, which I gave up on because it kept giving me random HR readings.
The Timex one is better, but still not great. Am I wearing it wrong or is it faulty?
Yesterday on my half marathon, it seemed to be showing the correct heart rate about 75% of the time. The rest of the time it was either way too low, or way too high (eg 70 or 280!)
I wasn't running close enough to anyone else for it to pick up their HR reading, if they were wearing a monitor.
So, is it me?
Is the product likely to be faulty?
I wet the sensors before putting it on, but, ladies, where exactly do you wear the strap? Do you jam it right up under your boobs (sorry, lads!) or do you wear it a bit lower?
Any advice before I send it back?
