In reply to climberchristy:
I'm good, cheers. Just in the writing up and panicking stage now! How are the injuries? Have you got the sign off for running yet?
I really like my 935. I ummed and ahhed about buying it as it's massively overkill for my level of running but I decided to treat myself in the run up to the Lakes 10 Peaks last summer. I like the optical HRM, I know they're not as accurate as a chest strap but having seen a friend's wicked underboob chafing I'd rather not use one! I also really like the fact that it has a barometric altimeter so you can use it for nav on mountain marathons. I don't use the smart watch functions that much when I'm running, although I do occasionally use them to control the volume of music on my phone and I tend to use them if I'm wearing it out and about. The general battery life is great and I only charge it every 2-3 weeks.
My only beef with the watch is the size of it, though all the sports watches with lots of techy toys are the same really. They feel very much designed with men's wrists in mind, not girly skinny ones. It's not a problem for using it for sport but it does mean I don't tend to wear it for general use, so a lot of the functions like sleep tracking and all day heart rate are wasted.
