Just bought a refurbished Garmin Forerunner 405 w/ HR,USB,AN

I was looking at those today on Amazon .. they look awesome!! I hope it works for you.

I've had one for about 2 1/2 years now to track my heart rate when I was walking big hills and felt like I was nearly dying - I thought I was just unfit and would push harder. When the doctor told me to track my heart rate, my garmin showed me that I had been working in the 90-100% Zone for about 10-15 minutes at a time, so not only did it save me from a serious problem, I just absolutely love it's interactivity - I love that it sends it directly to Garmin Connect and that you can set up all the screens to suit yourself - it'll do all the calculations you want and more.

Here's a sample of how Garmin Connect works if you don't already know about it (and don't laugh at my fitness - I've only just started to learn to run :-) )

The player on Garmin Connect adds a whole different dimension too - I can see exactly what I was doing where and when and it plays back in google maps. This helps me track my fitness and shows me the effects of not exercising for a few days or the foods I've eaten - it takes all the emotion out of it and the facts don't lie to me, so it helps me be more honest with myself.

If you need to know anything technical, use the Garmin website and don't hesitate to contact them - they are friendly and get back to you.

I don't use half the functions that's on it, but it is more than awesome and I wouldn't be without it. I use it on my bike (but I don't have a cadence monitor) and while roller-blading - I also used to use it when riding our motorised scooters so we could track where we went. I just wish it went in water so that I could use it while swimming :-)

I have this one. I'm an endurance athlete, so I put some time and effort into finding the best gps hrm. This is what I finally settled on.

Danielle-it's 5 am here, so I'll post more in a little bit, I just wanted to let you know to look for a bunch of answers here later today.

Okay-sorry for the delay.

The garmin 405 has a feature that allows you to "race" yourself. You can run, then load that course onto the watch as a course and race against your previous time.

The watch also has workouts built in like intervals, speedwork, and a workout geared strictly toward heart rate zones.

Garmin connect is the bomb! The options are endless and it makes it easy to record running conditions and see your improvement. You can designate one course a race, another a trail and another street running.

It's got a "back to start" function in case you get lost while trail running.

More in a bit, I've got to think about what other functions I use frequently.
