Not worth it

By ivos runner

from stoney creek, ontario

Comments about TomTom Runner Cardio With Built-in Heart Rate Monitor:

I had this watch for two years at first it seemed okay - the glass cracked phoned Warranty and they said - sorry you had it for over a year no longer under warranty - ran my first marathon in 2016 the watch battery died at 38.6 km - ran my 2nd marathon in 2017 and it also died around the 38 km watch. The HR is not accurate at all - indicated 178 BPM during a walk - my Fitbit on my other wrist indicated 95 BPM. Will not advise anyone to purchase this watch but to look at other brands as I am.


Just what I wanted

Comments about TomTom Runner Cardio With Built-in Heart Rate Monitor:

Love this watch. I bought it for the multiple OCRs I do every year and this watch has lasted through the mud, the water, and has taken quite a beating from the obstacles. I also wear this watch on a regular basis running outside and on a treadmill. I love the GPS function solely for mapping out my OCRs and seeing the elevation change and recording my pace. I've had this watch for about 2 years and I am amazed that it is still going strong. After 2 years the 3 little rubber nubs that hold the backside of the band down finally ripped off and I am looking to buy just a new band for the watch. For what I have put this watch through, it was well worth the investment.

Heart Rate Monitor? - Eh, no.

By ProRunner

from Undisclosed

Comments about TomTom Runner Cardio With Built-in Heart Rate Monitor:

Skill Level: 29 years old runner, 40-50 miles per week averaging 7:30 miles. I use the watch for easy runs, long runs, tempos, track workouts, etc. After days of research between different watches and brands I settled on the Runner Cardio for it's built-in wrist HRM so I'll start there. HRM: I rarely obtain an accurate measurement. Most of the time it records my HR at heart attack levels. Based on TomTom's advise, you should tighten the watch "comfortably," clean the sensor after every use, and keep your wrist dry during use. To get anywhere close to an accurate measurement you have to cut off the circulation to your hand and I wish I was exaggerating there. Even then, once you start sweating, the HR reading jumps to death levels (180+). I eventually quit bothering with the monitor at all, but wish I would have gone with a better gps watch while foregoing the HRM. GPS: The GPS is actually quite accurate. But only for 3 days without updating the "QuickGPS" which helps locate your position quicker. If not, it could take minutes to find a signal--not fun in 3 degree weather. That's not a deal breaker, just an annoyance. What is a deal breaker is you can't "start the clock" until it obtains a signal so even if you start running without a signal, you can't start your time until the watch is ready. Functions: The workout functions aren't bad, you can set 2 small display readings and one large, for instance HR, Pace, and Distance. I wish you could view these readings while in Stop watch mode though. All runs are uploaded to your TomTom website page which shows different readings throughout every run. I wish it uploaded stop watch recordings though.

terrible terrible watch!

By Ana Padros

from Dallas, TX, United States

Comments about TomTom Runner Cardio With Built-in Heart Rate Monitor:

This watch is nice looking, and that's where it's qualities end. I have always been a Garmin user, but I am not a very technical person, I just want to know my pace, distance and heart rate and since this was one of the first products that included a wrist heart rate monitor I decided to go for it. It has been a huge disappointment, batteries will never live through a long run above two hours, which for any endurance athlete is a big must, the pace takes forever to adjust so if you are doing intervals, be prepared for major burnout because you will be doing full speed before the watch actually adjusts to your pace, I ve been trying to make it work for a full year now and really cannot find any qualities to it.....I Am really disappointed, I really dislike this watch
