Its not as simple as just comparing two heartrates but depends on the state of one's training and the percentage of glycogen and fat one is burning at any given intensity. In general though one will burn fewer calories per mile at a lower heartrate than at a higher heartrate because fat/glycogen burning ratio is greater at…

My understanding is that one should burn fewer calories per mile at a HR below their maximum aerobic threshold simply because fat provides more energy per gram burned than glycogen. Most HR monitors have no way of taking this into account accurately.

It also depends on the HRM and the way it calculates exertion. Sunto, some Garmins and some Polars use HR variability and also keep track of your changing fitness levels. In my experience these seem to give believable and consistent calorie counts for running although they are a little lower than the numbers given by other…

I checked mine online and it says I need to weigh about 163. That was withing 2 pounds of my goal weight anyway so 15 pounds to go. I haven't weighed that much since high school so it will be a new running experience.

While this seems like a logical way to get faster it won't work for long. While sprinting you are not building the aerobic system which in any race over 800 m is the predominant system providing your energy. Even in a 5K 90% of the energy is provided aerobically and only 10% anaerobically. So what you are doing is working…

I did one this morning but it was three 10 minute intervals and i ran them by heartrate (about 86% max HR). The total run was about 7 miles. They are a good way to get in some faster running without trashing yourself.

I disagree that you cannot learn a new running form. A couple of years ago I was a heel striker and was suffering the usual low grade constant knee pains from running. I retaught myself midfoot striking and overall good form and have completely eliminated all pain. Plus, I have tried and I cannot heel strike and overstride…

I may look ridiculous, but I don't get injured, I run a lot, and I am one of the faster racers in my town. Over 50 years old with a 20:06 5k, 1:35:25 HM, and 3:32:12 marathon. Good form works and allows you to run at any speed pain free.

When you are out of shape its really hard to burn lots of calories. Once you get in moderate shape its easy to burn 1000 cal in 90 min or less of moderate intensity running every day in once or twice a day sessions

My opinion is that you are much better off training by time rather than aiming for someone else's mileage goal. 70 miles for one person (8 min/mi) might be 9 hours of training. For another (12 min/mi) it's 14 hours of training. The second training load per week is nearly 60% greater and is as much or more than elites…

It depends on how much you weigh but it's probably less than 400 cal.

As it gets warmer it you will have to work harder to maintain the same pace. The reason is that some of your blood that normally is carrying oxygen to the muscles is now diverted to the skin for cooling. So your heart beats faster and your breathing increases. The solution in training is to either run by feel or heartrate…

90 to 100 min is good but 2 hrs would better for stimulating the desired (long run) training adaptations, particularly during base building. Much more than 2 hrs causes excessive tiredness for only marginal gains.

You still need a weekly long run of 2 to 2.5 hours for best results.

If you do choose to run this marathon I would recommend you use the Galloway Training plan for this one. It will get you over the finish line with minimal injury risk.

I ran a marathon in vibrams once and the bottoms of my feet were really hurting by the end LOL. Now I switch off between vibrams and Brooks Pure Connect and my feet feel a whole lot better all the time. The brooks are great because they allow for the exact same running form, they are about as light as vibrams, and they are…

You are running enough then although it will be tough. Given your current time in the half you can expect a marathon time of of around 5:30 to 5:40. If you choose not to run this marathon and want to continue improving your running long term I would recommend you commit to a long term mileage build and do it for about 6…

Yes you could run a marathon in the fall. But the real question is are you running enough recently to support a good training build up. What is you average weekly mileage over the past several months?

I lost 10 lbs in 3 days once by not eating anything. Then I ate and gsined 9 lbs on the 4th day.

170 isn't dangerous as long as you don't have any heart problems. But you're a whole lot better off exercising at a HR of 150 to 155 and going longer. Your HR will begin dropping quickly and you will have to start speeding up.

I'm rebuilding right now so I presently run every day and twice a day on 5 days. Most is really low intensity so recovery is quick.

The strength work will be good for you. But mainly you need to run loose and relaxed. Also take a look at your overall form and alignment. Google "Good Form Running" for pictures and explanations.

It's caused by inadequate glycogen so you are burning protein for energy. Eat more carbs.

I have both a Fitbit and an iPhone. The step counts are always very close and the mileage on the iPhone seems more accurate. It appears to be able to account for changing stride length on the move.

Nothing but a cup of coffee.

I run twice a day often. It hasn't really speeded up weightloss but I do eat more and continue losing weight at a steady rate. What it has speeded up is my return to running fitness.

At the distances we are talking about here speed is really just stamina. That is the ability to hold your faster speeds for longer periods of time. stamina = easy effort runs x time with a small amount of moderade LT effort topping it off. In my personal experience (others may differ), from the time you begin training…

What you should focus on now and for at least the next 3 to 6 months is just building a good aerobic foundation by running easy for progressively longer times. Easy is with your heartrate at around 75% max and below. This is important. Running harder than this right now is not better. Progressively longer times is to where…

I was just responding to the statement that HIIT is that hardest thing you can possibly do. It's not. I will agree though that maybe to an untrained person it is since they haven't developed the capacity to do or even imagine something harder.

Well, I was the one that made the statement and at the time, 2 years ago, I was running up to 100 mile training weeks, so maybe I was quite fit, and I measured my effort over those races with a HRM, and I know the max my HR ever reached in that time period, so maybe I do know what I'm talking about.
