Timex Marathon GPS T5K638
Available in two variants, with and without heart-rate monitor, it has a nice design and combines the technical skills of a first floor, the sirf star 4 GPS antenna, which allows the satellite fix in a few seconds (except the first use, which may take several minutes) and the display can also show 4 rows of data (depending on the screen), and it is always visible in all conditions, thanks to the excellent lighting indiglo.
Very complete facilities, such as asking to professional models, this model allows you to view real-time pace, speed, distance, altitude, and also provides the user with recovery timer, customizable timer hydration and nutrition through customizable screens and allows you to keep track of everything you need to an athlete during training.
You can then store and eventually download the data of 15 complete workouts. I think the most popular model will be the one with the heart-rate monitor, in addition to which you can also use a sensor pod to control over heart rate even pace. The lithium battery can be recharged by connecting the watch to the PC via the USB port and has a range (in GPS mode) of about 9 hours, does not stand for life but still allows you to securely manage your workouts.
By purchasing this model, we have also free access to online software run by TrainingPeaks. To complete the picture of this Timex Marathon GPS T5K638 waterproof protection equivalent to 50m, more than enough for the type of product. The value for money is good enough. This model is positioned approximately mid-table compared to direct competition.
Personally, I consider this Timex a good product, although I’m not a great athlete, and I have only tested the product during some output in mountain biking; I will surely have overlooked some aspect that could be vital for use at a high level.
