I was a bit hesitate to purchase the marathon pack, I felt it was a bit more than I needed, but after utilizing all the accessories I deemed it the best training tool ever. It is the simplest way to track overall all performance, effort, and training effect. The Suunto marathon pack provides more than just a watch to keep track of laps, but if you want it to, it will also be a little coach letting you know to speed up, slow down, and relax. If you are just looking for a watch this is not for you, but if you want the versatility of a complete training tool, partner, and coach, I suggest you get one yourself. 5 stars

Learning coach including in the Suunto T4 with pc-pod and foot pod reveal running strength is adequate or not.
One of the impressive point is the coaching is not limitted to the data inputted into initial setting. The coaching is a self-learning teacher living in the watch.
Of course, for a speciallist, there is no need to learn running strength for health promotion or improve his body.
As to me who has not enough knowledge and experience, very usuful guide which is shown in the watch windows and PC-software. 5 stars

I bought the Marathon pack a couple of weeks ago and I have recorded 8 different training sessions. I really like the ability to download the logs onto the computer and see your improvements and differences between sessions. The coach I think will become more useful when I have recorded a bit more data and it has a better idea of my average week. The strap as mentioned in other reviews is a little annoying, but in my opinion the best looking for the T4, so I trrimmed it down and put a dob of glue to stop it coming loose. The Menu system is a little confusing at first, and probably harder to get used to if you've always used a Polar, but I have no problems with it. I have had no problems with the footpod, other than forgettting to turn it on (not really suunto's fault). I have found the T4 a great tool to keep myself motivated and interested in running. (This is the first HRM I've owned/tried so I think it would be unfair to give it 5* without testing another) 4 stars

BASTANTE MALO ESTE PRODUCTO, PRIMERO FUE FALLANDO EL RELOJ Y CUANDO POR FIN LE COMPRÉ EL ACCESORIO A MI BICI, MURIÓ, NADIE SE HIZO RESPONSABLE DE LA COMPOSTURA ME DURÓ MENOS DE UN AÑO Y 400 DLS MENOS, ME NEGABA A LA IDEA DE UN POLAR, PERO NUNCA HE TENIDO UN PROBLEMA CON ESTE EQUIPO. MI HERMANO SE COMPRÓ EL T2 Y SE LE METIÓ EL AGUA....HAY MEJORES OPCIONES TMABIEN ESTÁN LOS ALEMANES PSIGMA, EXCELENTES RELOJES. 1 star
