    Google says between 200 and 450 :/

    yea. its kinda hard to determine exactly. not sure if someone has any specific sites that are more reliable. I'm seeing that because 12% incline is high...probably near the 400 to 500 mark.

    Are you holding on to the treadmill?

    i'm getting 444 at 10% incline and 559 at 15% so i'd say 500. if you need to be really tight on your burn numbers, i'd go with 450 and error on the side of caution. sparkpeople.com/resource/calories_burned.asp?exercise=201

    Nope :) doesn't holding on mean you burn less?

    This calculator comes from studies done on grade vs. energy expenditure and should get you pretty close:

    Hmmm idk how to convert feet to percentage lol

    Elevation gain = distance * grade * 5280 (convert miles to ft).

    If you did an hour at 3 mph, that's 3 miles * 0.12 * 5280 = 1900 ft.

    The calculator assumes a round trip, so I had to put the trip in as 6 miles to get just the 3 mile uphill portion, which gave 480 calories. Although given the actual study data it pulled from, this seems high. When I ran the numbers using the graphs from the data, I got 340, which seems more reasonable.

    Does the treadmill ask for your weight? All of the ones at the gyms I've seen in the past few years have that as an input and display a Calorie count. If so, I'd just go with that number and monitor how your weight does using that over time - adjusting as necessary.

    Edited because I somehow thought I was in a different subforum. Whoops.

    Doesn't the treadmill give you an estimate?

    Your calories expenditure would range 200-450 because your height, weight, level of effort and efficiency are unique to you at that time. The google calculation range is just a guess for anybody. I'd guess your calories at 200 and suggest do NOT eat them all back.

    A heart rate monitor configured for your weight and height, will be tighter.

    For low intensity cardio like walking/hiking, an HRM will not be accurate. HRM based calorie counts are only accurate for moderate intensity cardiovascular exercises. And even then there are quite a few caveats.

    I let mfp guesstimate it. Can't afford fitbits and stuff. As a rule of thumb, eat back only half of estimated calories burnt.

    I have a fitbit with a built in heart rate monitor - I've found this to be very accurate.
    These are quite expensive - so another way is by reading what the burn on the treadmill monitor says and perhaps half it (The burns shown can be a little over-estimated) :)

    I use the map my run app, it's part of MFP.

    It has GPS for outdoor activities so it will calculate automatically that way. It also allows you to log your own work out. I do a lot of indoor biking, so I enter the distance and the time and it calculates for me. The best part is it syncs up to MFP so it will automatically log the calories burned for you!

    This is a slippery slope. It is easy to lose too much like this. It is not so significant for low calorie burns but for long cardio exercises which can easily go up to 1500+ burned this would be fatal.

    Agree - I really don't like the often blanket advice to halve calorie estimates without context to the type and volume of exercise. It's not that hard to get a "reasonable" estimate with a bit of effort for most exercise.

    Did a little experiment out of curiosity at the weekend to compare calorie estimates for a long and hilly bike ride:
    Strava - 2158
    Garmin - 1909
    Polar HRM (calibrated to my personal HR range and VO2 max) - 2705

    Polar is the most likely to be fairly close as it tends to match the very accurate power meter equipped trainer I use and other reliable sources.
    (I took off a percentage to allow for stop/starts by the way.)

    If I halved any of the estimates I would have a huge deficit !

    By the way the often castigated MFP database would estimate 2790.
