    5.0 out of 5 stars Seriously good gadget for serious athletes 21 April 2008
    Verified Purchase
    OK, first looks - you are thinking to yourself "But what if someone tries to land a helicopter on it's enormous surface while I am out running?!"

    Well, don't worry about it. Yes it looks bulky but when you are out running you never notice the size and it's easy to appreciate the highly configurable and easy to read display. This device is all about options. I choose to run with the four following items all simultaneously displayed:
    Heart Rate, Elapsed running time, Average pace in km/h and Total Distance

    I can of course choose to see other bits of information and have the screens changing at intervals I determine but part of the joy of running is getting away from it all and looking where you are going! The device just works, capturing all that lovely information about your heart, what kinds of slopes you are running on, how far you are travelling.

    I once got lost in some big woods near where I live, then I simply turned the watch into navigation mode and was able to trace my way back through the forest to where I started from - absolutely brilliant gadget.

    The real fun with the Forerunner comes when you get to analyze the data. The software provided with the watch is very basic. Most people I know download the excellent Sport Tracks software which is freeware from Zone 5 Software. To use this software you also need to have installed on your Windows PC a version of .NET from Microsoft (this is just some extra software for the Operating System to allow programs written in a certain way to run - again, it's a free download from Microsoft).

    Now you can amaze your friends and family about how far you run, how fast you go, how big the hills are you are running up, amaze them with how many calories you've burnt off.

    5.0 out of 5 stars Excellent 25 Sep 2007
    This is an amazing device. I thought I would add the following to previous reviews.

    Answers to the questions I couldn't sort out before purchase (as a triathlete):
    1. Can you swim with it? Sadly not. Although certified as waterproof it is not sufficiently watertight to swim with.

    2. Can you download routes FROM memory map TO the device i.e. brand new runs/bikes planned at home on the map? YES - but you need to upgrade memory map 2004 software to the USB supporting version via their website. The device will then guide you around the planned course.

    Added suggestions:

    Everyone should check out SportTracks software (shareware - zonefive) which is vastly superior to the Garmin packaged applet. SportTracks integrates with google earth and automatically generates satellite images of your route.

    The pre-loaded advanced training packages are good for turbo sessions. Obviously the GPS is useless but the watch will monitor your heart rate & cadence (with attachment) and instruct you through a pre-set or custom pre-programmed workout e.g. Cycle in zone 3 for 5 mins; Cycle in zone 4 for 2 mins etc.

    Other bonuses over my old GPS and heart rate monitors:
    It charges via USB while connected to the computer.
    It has a coded heart rate belt - no cross-talk in the gym.
    It has excellent GPS reception in the woods (much superior to my Geko 301).

    All in all: For £150 a bargain. It has virtually replaced my old HRM and my GPS.

    Downsides? £150 is still a lot. The large unit might put you off. It looks a bit retro. Can't swim in it. I now *know* that I run as slowly as I thought!

    4.0 out of 5 stars Great Gadget 1 April 2008
    By R. J. Hole VINE VOICE
    Verified Purchase
    This is a good gadget, one that is getting plenty of use. It has certainly made me change the way I run and encouraged me to find out more about different methods of training. The first time I used it I set it to alert me whenever I dropped below a certain pace and I ran my best time for that course. The heart monitor works well but I recommend that you set your own heart rate zones as they were too low initially. There are plenty of links on Runners World to help you do this. I used the formula 214-(0.8*age) to get my estimated maximum heart rate which seems to work well enough for me. Working out the zones was not immediately obvious so take bit of time to understand how they are calculated. You have to apply the percentages to the Working Heart Rate then make sure you add your resting heart rate otherwise you find your zones are much too low.

    The Training Center software is reasonable for looking at the recorded data on your PC. The map is only useful to identify whereabouts you were, e.g. I can see that my maximum heart rate was near the top of a hill that I decided to run up quickly. The map is just a dotted line and the elevation is not all that accurate. From Training Center you can also view the route in Google Earth.

    I also load the data into MapMyRun which gives a proper map with satellite pictures (similar to Google Earth but without the fancy stuff like 3D) which makes it easy to see off road routes. It also shows the elevation profile which seems a lot more accurate. The best feature of MapMyRun is for inputting new courses you are considering. It makes it easy to design a route that will be the distance you require. You can load these back into your Garmin and use them as routes.
