So, my cycle will be arriving in a couple weeks, and I am getting ready! It's not a bicycle (which I know is what this forum is mainly for, but my question below applies to either). Mine is a quad.
Anyway, I have a Timex Ironman Global Training GPS watch. It shows distance, speed, and calories burned data (main info I am interested in) as well as other data. I use it currently when walking for exercise daily. However, like I said, my cycle will be here soon, and I wonder if it will work with it. I can see how it would get distance and speed via GPS with no problem. However, how does it calculate calories for bicycle use? Would I have to have something else for it to provide calorie info? I know there are cadence sensor that are for bikes, but is that required for the calorie info? Basically, if it can work without that, I would prefer to have one less thing to worry about the battery being charged on. Every once in a while my watch ends up without a sufficient charge mid-walk as it is.
From what I've read in the Forums, early calory calculations were based on speed only, even with devices with heart rate info. Most current HRMs take heart rate and user's weight into account. I assume the Timex has heart rate functions?
In any case, measuring calories is not an exact science with these devices, you'd need a lot more sophisticated stuff or even laboratory conditions for that.
To err is human. To moo is bovine.
Who is this General Failure anyway, and why is he reading my drive?
A quick note. My new Garmin 110 (I have had the 305 and before that the 101) has a neat program for calories burned. It has gender/height/weight/age and activity level fom zero to 10. All this gets a little closer to "actual" calories burned. I have used this new watch on my runs as well as my rides. Seems pretty consistent as far as calories burned from my observations of various measurements over the last 3+ decades. As a male, 5'10, 145 lbs/67 yrs old with an activity level of 8 I burned over 6,500 calories on a recent 72 mile bike ride (avg 14+ mph) on my Trek FX 7.3 hybrid. I rarely look at the calorie thing--but it is fun sometimes. I have run nearly 72,000 miles over the last 34 yrs--so weight has never been an issue. Back on a bike since May and close to 3,000 miles ridden. Long live Hagen Das ice cream!! Nick
depends on your budget and if you really need the GPS. The Polar cs400 and cs500 would do the trick neither has GPS; the cadence sensor is separate. They'll give you distance and speed plus your HR data though. The cs600 has GPS in it, but I'm not sure about battery life. It's also lots of $$
the CS300CAD comes with the cadence sensor I believe. You could also get an older s720i or s725x. I have an s720i and it works great.
