    SO TRACKING QUESTION

    Today, as an example, I ran on the big fancy expensive dreadmills at the gym. I set the controls for 7.5 MPH (8 min pace) and random incline with an average of 4% grade. I ran for 61:15 and the dreadmill registered 7.65 miles. I overshot my hour target but that is a secondary point...

    I tracked the run using my Gramin 935 and Garmin footpod. I have run with the footpod many times outside on auto-calibrate. The Garmin claims I ran 7.99 miles (had I known I would have kept going lol) at 7:41 pace for the same 61:15 time.

    So which one is more likely to be correct?

    I am no expert, but as a guess... The dreadmill is measuring distance because it knows how fast that belt is moving and can figure out pretty accurately what the distance was.

    distance = speed (miles per minute the belt is moving) x time (minutes treadmill operating)

    The footpod? I do not know too much about how they work in accuracy, but I believe they are using gyroscopes to measure quick changes in movement to figure out how many steps you're taking, estimating when your feet are on the ground vs in the air, cadence, ect. My guess is that the footpod is estimating distance by counting your steps and then applying what your average stride length is. If I remember right, they say you have to run outdoors in GPS mode a few times for that thing to work and understand how you run? The only problem I would think with that is, people run differently on a treadmill (smooth belt going a constant speed and forcing you to maintain a certain pace) than outdoors (uneven surface that remains stationary). That and GPS distance is extremely inaccurate for measuring precise distances. (remember our discussion on running the tangents and how race courses are certified distances)

    DCRainmaker thinks highly of them: https://www.dcrainmaker.com/2011/01/garmin-ant-foot-pods-everything-you.html

    He says:
    I've found time and again that the latest generation of foot pods are incredibly accurate.

    But, rereading that I am remembering that I have not tried his calibration tool yet. I will have to do that and see what happens. That might change everything.

    ETA: No I will not :( It is Windows only. Bah.

    I have a 20% off full priced item coupon at REI and I'm going to pull the trigger on a hydration vest.

    Anyone familiar with the Osprey Dyna 6 or 1.5? I've tried a few on, and so far I like this one the most.

    So, there's supposed to be 8 inches of snow from tomorrow morning through Saturday morning, right where my Saturday race is.... Seems like a decent amount of people are dropping already... AG placement for slow old me??? Bring it on!

    @MNLittleFinn enjoy! And have a great race! My strategy would be to stay in the back and let others pack the snow down for me.

    That's EXACTLY my plan. I'm back of the pack anyway, so I figure I should use it to my advantage.

    @AlphaHowls - Wow, you run a crap ton of miles with little rest. Do you have an injury prevention routine? Do you mind sharing? Thanks!

    This is a list of foot care tips for runners from a podiatrist who is part of our running group. I thought some of you might find it helpful.

    @kevaasen- Interesting! Thanks for taking the time to do the calculations. It's interesting to see the comparison between our cadence and strides at a similar pace. What do you think beats you up more, running a 10K race or a long training run? For me, it would definitely be the race, even compared to a 20 mile run.
    /quote]

    Great question! Likely the race as well but the endurance of running a 20 mile training run is not easily dismissed as for me that would be closer to a 3 hour event and that produces a lot of time to have a different type of impact on both the body and for the mind (easier if I’m farther from car or home to finish the distance if/when my thoughts start having me wanting to stop etc).

    @PastorVincent - I'm glad you solved the footpod vs. dreadmill mystery. I don't know that I would trust either one. The footpod has all the issues you identified. There is an economic incentive for dreadmill manufacturers to make users think they ran faster and further so I would expect any dreadmill measurement error to be biased in that direction.

    A piece of anecdata for you: I've worn a Garmin 620 or 630 on indoor track workouts without GPS signal. It tracks cadence from an accelerometer in the watch, no footpod; a footpod should be more accurate. It does autocalibrate from my running with GPS. I've found that it under-records the known track distance at an easy pace, but over-records the known track distance when I'm running hard. A buddy who has a 610, with footpod, sees the same thing but with less error because the footpod is inherently more accurate than the watch-mounted accelerometer.

    In any case, the error from footpod or wrist mounted watch wasn't big enough to worry about on the scale of how many training miles I ran. I didn't care much about the Garmin-reported pace for those workouts, as the important thing was typically timed intervals of known track distance.

    March running total to date – 122.81

    Nominal challenge goal: 180 miles

    Real goals: Build base. Work toward being able to run 26.2 miles by Patriots' Day.

    Today's notes – Went to club practice this evening, but in light of my fall Tuesday I opted to just run some easy miles after the warmup. It was good to see guys I knew, and some new arrivals; Coach had a new guy run easy miles with me. He is naturally faster than me, and we helped each other slow it down. Had a nice conversation about injury prevention and how to train; I was taking it easy with about 4 miles after the warmup, and he was all done at 3.7 miles. Had another one of those "oops" conversations; I asked what his target was, and he said, "800." Oh, I said, a sprinter. No, he is a mid-distance runner.

    I can't help myself. To me, anything less than a mile looks like a sprint, and a 10K looks like a nice mid-distance race. But the accepted terminology for track running has "mid-distance" being shorter than a mile, and I'm not sure how long "sprint" goes. I guess I need to learn the vocabulary if I'm going to talk to different types of runners.

    6 miles dreadmill. Normally don't like the dreadmill, especially on nice days like today, but trying to target a specific pace for a specific distance and I don't do so well with targeting a specific pace outside on my own.
