10/2 - 41.9 miles 10/4 - 26.4 10/5 - 24.9 10/7 - 24.9 10/8 - 29.2 10/9 - 35.8 10/10 - 60.7 10/11 - 26.1 10/13 - 24.4 10/14 - 36.1 10/17 - 121.2 - Met my season's goal! Well, the century mark for the ride would have been at 5:23:17 moving time except for a wrong turn that lengthen the ride. Fun ride but wasn't quite ready…

For me, Endomodo gives the lowest estimate. Strava is always on the high side and MFP in the middle. If you are uploading to Endomondo, it will reflect what in the file's header instead of recalculating based on the data set. Strava recalculation based on what's in the data set and makes its own determination of the path…

Ops, lower calories efficiency increase calories expended. Got a chance to run the calc and was too high on original post. Here is the stats from my afternoon ride: Time Riding: 1:53:45 Distance (miles): 35.84 Work (kJ): 1330 Average Speed (mph): 18.9 Calories @25%: 1272 (+29% different from MFP) Calories @23%: 1382 (+21%…

MFP is overestimating by a factor of 40% for me. I log the results of my bicycle rides based on power recording from my power meter (closest one can get other than actual laboratory testing although some may frit about left only, left/right, and branding); however, I have not paid for laboratory testing to determine my…

Recumbent vs Upright Exercise Bikes, level of comfort, see http://www.indoortrainingbikes.com/recumbant-vs-upright/ (first google hit).

It a finishing tool to hone in peak performance on key event - it pushes once's lactic threshold level higher and increase the duration one can maintain that fatigue intensity. The immediate benefits are short lived due to accumulative fatigue although the overall adaptation does linger. It's also not something that can be…

You need an Ant+ HRM, see http://www.dcrainmaker.com/2015/04/garmin-vivoactive-in-depth-review.html. They are pretty much the same under the hood although the built (bells and whistle) may be different.

^ this The primary benefit of training with a HRM is to help keep you within a targeted intensity range (see http://www.joefrielsblog.com/2010/05/quick-guide-to-training-with-heart-rate-power-and-pace.html as a start). And for small subset of the population, HRM when properly calibrated and operated within a narrow band…

September was a bust - heat rashes that took a few days to dissipate followed two weeks off to deal with a family emergency. Here is hoping for a better October. 9/1 - 25.1 miles 9/2 - 25.1 9/3 - 16 9/5 - 101.1 9/11 - 25.6 9/26 - 41.9 9/30 - 15.5 Ride Time: 13:23:40 :( Goal: 45:00:00

It depends on the number of satellites the device can capture and what the post-processing method used. Mobile phone has the added advantage of able to refine the triangulate using the radio signal from the cell towers which a pure GPS consumer based device lacks. App based programs such as Endomondo, Ride with GPS, and…

Other than risk of damage or loss and convenient, you have a very capable computer for all of the activities listed. For cycling, walking, & running (I don't run and hate it) I use IpBike (~$10) app. Most other sports can be track using Endomondo (including cycling, walking, & running). Not sure what apps are out there for…

9/1 - 25.1 miles 9/2 - 25.1 9/3 - 16 9/5 - 101.1 My fastest century to date, 5:23:24 ride time & 6:22:20 total with 1,447' elevation gain (Ride w/GPS but my computer registered only 893'), albeit void of any climbs but had a decent head wind for more than 20% of the ride at over 10mph and did a fair amount of work pulling…

Maybe a stab in the dark approach? Again just pointing out there is a difference, which you begrudgingly demonstrated. Statistical error and individual composition will of course increase or negate the differences (although negation is not likely for the untrained). But guess nuance is not you thing.

The assertion was there is no difference in calorie expenditure for running at differing intensity. No one was talking about walking vs running. Stop twisting the analysis to make it fit. Whether the OP has the fitness to made a big difference is another matter altogether, but stop give out bad information.

First it was the same for 5mph vs 10mph now picking a more narrow range... how convenient. Point is there's a difference whether you like it or not.

Might want to consult Compendium of Physical Activity, https://sites.google.com/site/compendiumofphysicalactivities/Activity-Categories/running and supporting references (scientific studies).

Congratulations @m1xm0d3! Ditto on ultra impressive. Looks like you're more than ready for that century.

That because you're roughly in the same intensity zone with respect to the metabolic pathway utilization. Pick up the pace and there is a difference.

Except our metabolism is not linear and different pathways are used depending on the fuel used, your efficiency, and availability of oxygen, molecules, and other enzymes. You DO burn more calories for energy production when you work at a higher intensities. Whether that's significant depends on the duration and intensity.…

One would need more than a day for the adaptation. Also it's highly unlikely one would be running at VO2Max for 1.5 miles. Reverse, high to low, yes. See http://sportsscientists.com/2007/07/altitude-training-the-basics/

Figure of speech and no idea the police thing. I hated and still hate running. Wasn't best of shape when I went in but still able cruise on a bike at over 20mph for two or more hours and sprint over 40mph on flats. Cycling is my sport. There were folks worst shape than me and made it through with flying colors. Military…

Unless things change a lot since I enlisted, your will be doing PT as part of the basic training. I went from unable to run for more than a few feet to 13:54 for my 2 mile test in eight weeks (Army). The training consist of progressive longer run and faster pace. Don't waste your time sprinting.

Old La Honda to Skyline & Sand Hill Loop from midtown Palo Alto in the SF Bay Area. About 35 miles with health balance of climbs, rollers, and flats.

Ditto! I sweat even when having a meal; soup is the worst. Doesn't matter much what the temperature is outside. I can be soaked skiing/snowboarding; I'm not that good, stay on the bunny slopes, and can only go sideways boarding. Steam can be seen coming off my head. I can also sweat after taking cold shower and not because…

Here is link to set your target zones: http://www.trainingbible.com/joesblog/2009/11/quick-guide-to-setting-zones.html. Your HIIT sessions should be at Zone 5a or above for LTHR or at or above Zone 5 for FTP. Keep in mind that if you are using HRM, the intervals will be over by the time your heart rate catches up.…

Although training can maximize one's VO2Max as it's largely controlled by genetics. Most people are confused with percentage of VO2Max one can sustain work for a certain duration (an indication of one's competitiveness) verse hitting (and exceeding that ceiling depending on the regimen) which HIIT calls for. It common for…

It's probably based some iteration found in the Compendium of Physical Activities. The collection, research studies, is limited in scope and application. Good luck on HIIT (the true application not just the hard interval training which most erroneously use the term for), it's very individualized.
