Yes, but they do get more expensive and larger the more they do....but Polar has a new one out that looks sleeker than mine, and I think it might have the GPS in the watch like the Garmin, mine has a separate gadget for the GPS part. But then I can use it either way, w/ or w/out the GPS tracking.

I didn't know HRMs could come with GPS and track so many things - wow, learning something new all the time and I'll be sure to look at models that combine the two features! Thanks for the info!

I can never get the app from Backpacker to work. I don't know if I am just not doing something right. For some reason it has a hard time connecting to my GPS. I can have an excellent GPS on Endomondo, but BP will still say it can't find me. I have been using Endomondo for GPS tracking but I totally ignore the calorie burn on it. It said 1900+ the other day and I really think it was smoking the weed in the woods. I have downloaded GPS Essentials which is supposed to be pretty good and I am going to try it tomorrow using my arm band pouch instead of sticking it in my pocket. It has a lot of bells and whistles you can add to the dashboard. I really want a new form of GPS as my smartphone only last about 3 hrs in GPS mode. Not so smart. For my calorie burn I am just going to continue to use my Garmin HRM to see if I get consistent numbers. And hopefully some day soon I can afford the upgrade to nice GPS w/ HRM.

For hiking I use the app from Backpacker magazine called Backpacker Pro. It does elevations, maps, interfaces with Google Earth, etc. It will also supposedly give you calorie burn if you put in your weight, but I have never got that feature to work. For my regular workouts, I use an app called CardioTrainer that has GPS and calculates calorie burn on a number of different exercises.

Those numbers sound reasonable. That's a good heartrate to maintain during a hike, and is in the cardio range too. Motivated@last does make a good point about the BMR and calories burned while working out, you can't really just add them together, especially with long workouts, which hiking can be. And when you're trying to lose weight you want to get to a deficit over the course of the week, so you still need to watch what you are eating. I think a lot of people can derail their efforts when they see large numbers of calories burned and think they can eat that number and not gain or continue to lose.

I can't help with the GPS app, since my Polar has GPS, but it's fun to see how far you went, and altitude monitoring is fun too, especially if you are doing hills.

Thanks for all the responses.

I use a Garmin. It is based on my age, sex, weight and height. I went over my heat rate graph after getting home and there were no crazy spikes. The highest I hit was 168. Mostly stayed in the 150's range. I am overweight (considered obese actually by my BMI by only 4lbs!) so I know I will expend more calories during exercise as opposed to if I only weighed 170. I use an app on my smartphone for GPS until I can upgrade my Garmin to a GPS one. Any suggestions out there???? Any favorite apps???
I found another app that I want to try that gives elevation and all that jazz. We are heading back out again on Thursday and I want to hike the same trail just to see if I get the same numbers again.

Another factor in the heart rate monitor calories burned is what kind of shape you are in. SOmeone who is in really great shape will not expend as much energy, and their heart rate will stay a little lower, than someone who requires more energy and a higher heart rate to get up those hills. So what one person's read may seem high but if it took a lot of effort for that person and another person was able to cruise up a little bit easier they won't burn as many calories. I don't think HRMs are exact all the time but I think they could give us a rough idea of what we've burned. Just like a runner who is in great shape will burn less calories during his run, even though he may go faster, than someone like me who is overweight, runs slow, but it takes a lot of energy to propel me forward LOL! So any of the answers could be right. Zumba is supposed to burn something like 400 - 600 calories an hour I think and hiking uphill over rough terrain would definitely compete with that LOl!

MTODRYK,

While the 600 calories an hour figure is feasible, I really doubt the 8400 calorie figure, for a number of reasons:

1. The standard convention for calculating exercise calories is to include your underlying BMR as well. As this is typically added to your BMR, this is technically double counting. This is fine for 30 or 60 minutes of exercise - the double count is pretty small. But when you start talking about 14 hours, the double count is probably 1000 calories plus.

2. While you might have start your hike at 6am, and finished at 8 pm, presumably that included lunch, rest and water breaks along the way, so the actually time spent actively hiking was more like only 12 hours.

3. 600 calories is a fairly high level of output, and is certainly possible for an hour or two. But to keep this level of output up all day is extremely unlikely - fatigue eventually sets in. Tranter's Correction en.wikipedia.org/wiki/Naismith%27s_R
ul
e
shows a clear drop-off in speed (and by extension, calorie burn) over many hours of hiking.

4. The body typically has reserves of about 2000 calories in usable energy, and can convert fat to usable energy only slowly. So somewhere around 2500-3000 calories, you will literally run out of energy. Marathon runners know this as "hitting the wall" - common at around the 20 mile mark in a marathon. So unless you are eating truly massive amounts of food during your hike, 8400 calories just isn't feasible.

Hiking is awesome exercise, and I don't disagree with it being possible to burn 600 calories in an hour. But to extrapolate that 8400 calories in a day is seriously misleading.

Not sure what kind of HRM you have, and what variables you have entered into it, mine is specific to my age, weight, height, gender, so I think it's pretty accurate. That said, it will give me off readings at times if the monitor is not reading my heart rate correctly. Power lines or other interference can make it go out of whack, and give me strange readings. If you check what it's reading during your hike/workout, you should be able to tell if it's doing that, it will give you readings that are way too high (into the 200's for example) and the numbers will jump all over the place.

I think in 2 and a half hours that number could be accurate with steep terrain especially my heart rate can really jump.

1678 would sound to be at the upper end of what might be feasible in that kind of time period.

HRM's can potentially overestimate in stop-start situations - best practice would be to stop your HRM while taking a break.

One thought as an alternate estimate might be to trace your route and log it as a workout on mapmywalk.com - this should take elevation into account.

that seems quite a lot. I always wonder how people get to burn 600-800 calories an hour. I never get over 400 according to my HRM, no matter how I "play around" with my heart rate. But if that's what the HRM tells you, I would go with it ,;)

The usual rule of thumb is 10 calories a min, or 600 an hour. I did an 14 hour hike and burned 8400 calories. It's because your heart rate is in the target zone basically the whole time. Other than swimming, hiking is one of the best calorie burners.

When I hike I always burn lots of calories. Walking up those hills takes a lot of work and even when you are resting your heartrate is still high so to the monitor (and your body) you are still working.

So hubby and I headed out this morning for his birthday hike. We took the dog who absolutely had to sniff and pee on anything so took us forever 2hr 50mins (2:20 actual walking time, I had to take a lot of breaks on those steep steps, and then the dog had to play in the water, then a 5 min break to refuel my gut) for 3 miles. It was all up hill, steep up hill with climbing rock steps and then some really steep man made steeps. I was carrying my new daypack, which I absolutely love, weighed in around 9.5lbs before adding the dogs water bottle, car keys, camera. It didn't even feel like I was carrying anything which pleased me greatly and I had a full 2L water pouch in there, snacks, first aid kit, dogs plastic bowl, flashlight, multi purpose tool, and compass. Only way I knew it was on was I was sweating down my back and the waist strap. Not uncomfortable just knew it was there.

Anywho, I wore my heart rate monitor and it says I burnt 1678 cals. Can this possibly be right? It was a lot of effort and my hips will hate me tomorrow and I was figuring probably around 800-1000 cal burn, but I was excited and surprised to see such a high number.
