Mark do the Parkrun then we will have you and Steve to cheer for this weekend 

It always takes a lot to catch up with this place after a few days away!

DWave - Hopefully one of your higher-priority races will go off, but if not maybe we can say "hi" in person. My thinking is that this race is small and in a fairly rural area and so will be more likely to run than something larger/in a more urban area.

Stryd: Most to all of the difference in the before/after readings when you upgraded are due to it taking wind into consideration - those same metrics tanked for me when I upgraded as well. I just looked at a couple old runs and my running effectiveness and efficiency index (per Runalyze) are both ~6.1% lower than before.

20W for someone your size seems a bit high according to my memory, though. By adding in the extra watts to overcome air resistance you end up with higher wattage at the same pace as before, which makes you look much less efficient. If you're on a treadmill (and not having to overcome any wind at all) the metrics should be the same/very nearly the same between the wind and non-wind models.

I'm guessing the power readings are due to you using a Garmin chest strap (HRM RUN or TRI, perhaps?) since there's no native power recording for Stryd in run mode. I know Garmin does their own running power calculations with some chest straps, but I thought they required their own CIQ app as well.

JMac - Hooray for the new addition! I hope and trust all in the house are doing well.
10 guys running around your speed? Man, I don't think I've ever run a race and finished near that many people.
I used to use HR pretty heavily when running, but have phased out of that over the last couple years. I find that going by internal effort and/or Stryd will keep my HR well within whatever zone I would have been using anyway.
Also, for Intervals do you prefer going to longer intervals (going to 5x 3:30 from 5x 3:00) or adding in a new rep (6x from 5x at the same duration)?

Mark - We wear the same size running shoe, so clearly I can't blame being slow on my big feet! Time to think of a new excuse...

Flavio - Great that your weather situation has approved, and awesome that you have your Altras locally, too. Sweet that you've got your Italian citizenship now, too, congratulations!
Good find on that Github script, I'm taking note of that. Fortunately I have most of my common workouts saved to my watch (independent of the calendar), and something like today's 6x 3 min on/3 min off was easy to setup on my watch as I walked to my start point.

I've done a good bit of travelling back and forth across the state in the last week-and-a-half due to my wife's grandmother's health going downhill rapidly, her passing, and the funeral. Old age - she was 92 and quite ready for it.

After discovering I had some credits at an online store I ordered a pair of Saucony Endorphin Speeds. Looking forward to trying those out whenever they get here - sometime in the next two weeks. Those things are surprisingly difficult to find (having big feet helped me here) - the men's version doesn't even show on the Saucony website!

Weekly for period: From: 07/20/2020 To 07/26/2020

Total distance: 81.37mi

Believe it or not I've had it saved on my computer for years now! A web form I used to regularly fill out required a file attachment each time it was updated (regardless of whether the proper file was already attached), so I used the dancing banana as a dummy upload since it's such a tiny file.

I had to upload it to postimages (Flavio found this, I think) and copy/pasted the URL here.

Old friend, how I've missed you.

Actually it was Piwi, who's our resident tech expert.

This board offers you the 5 star honor, the highest available, for your incredible achievement.

Longboat - very interesting (and I feel like an ugly American for not knowing that).  The weird thing is, I do recall some friends who had to give up citizenship, I thought?  But perhaps I was just confused.

When you get a job in the US that requires security clearance (some federal jobs?), they may ask you to renounce your other citizenship(s). Otherwise nobody mostly cares.

 

Ah, that might be it.  I have a LOT of friends with security clearances - it's pretty normal in this area, since a lot of people work for the government, or contractors, or law firms that do work on government issues, or similar.

 

 

As for the power oddity, here's the thing CK:  This is my new Garmin 735.  It is brand new out of the box, and because of the whole Garmin-being-down thing this watch has not been connected to Garmin yet (and I'm probably going to wait another week or so before doing so, just to be safe, since I have a nice pristine watch).  The 735 does not have the Stryd Connect IQ thing installed on it - it has nothing on it except what it came with out of the box.  And it's not refurbished (as best I can tell) - it's brand new and came in a nice new box.

 

So basically:

 

Situation one - Garmin 935 with Stryd Connect IQ app and non-wind Stryd - gives me one set of power readings telling me what a wonderful efficient runner I am.

 

Situation two - Garmin 935 with Stryd Connect IQ app and wind Stryd - gives me a second set of power readings telling me that I'm an awful non-efficient runner.  (according to Runalyze - a running efficiency score  .91 or below is "below average; .92 to .94 is average, and over .94 is above average.  My running efficiency score with the wind Stryd is .78.....)

 

Situation three - New out of box Garmin 735 with no apps installed and wind Stryd sitting on a shelf in my house - same power readings as situation two....

 

Which makes me wonder if Garmin will spit out some sort of power readings based on the HRM-Run strap, and ever since I swapped to the wind Stryd I've been getting those power readings and not the Stryd ones.  Equivalent to a watch pulling distance from GPS when you thought it was pulling from the foot pod.

 

The only common factor between situations two and three are a) the runner and b) the HRM-run strap.  Different watches, one has the Stryd App and one does not, and I'v been wearing the foot pod with one but not the other.

If you haven't used Stryd with the new 735 then I'd have to think that the watch is still calculating power via the chest strap and writing it to the file without showing the metrics (which requires a CIQ data field) - just the same as it was when my Stryd datafield kept dropping its connection.

I suppose it's possible that you've been getting some readings from the watch/chest strap combo - how do the power numbers you were getting with the old watch + stryd wind compare between runalyze and Stryd powercenter? From what I've seen, the garmin/chest strap combo would be ~40% or so higher than Stryd for the same run.

On my run with the wonky stryd data field values I also had a separate data field that showed power that came from the watch's connection to stryd as a power meter - that field showed completely normal values the entire time and matched what I saw in runalyze afterwards. Given that Runalyze took what was the "higher" power value between what was actually going on (likely written natively by the watch, but not shown) vs what the stryd data field showed and wrote to the file, perhaps Runalyze is showing you power numbers from garmin's chest strap rather than Stryd. That wouldn't be the case for me since I use a polar arm strap for HR. Definitely curious to see what difference there is, if any, between one of your runs in powercenter (if you use it) and runalyze.

My Running Effectiveness & Efficiency Index (similar, but different calculations) dropped in absolute values when I switched to the Stryd wind. Running effectiveness (Speed [m/s] / Power [W/kg]) is usually .93 for easy runs with the new model (.95 before), while my efficiency index (Speed [m/min] / Power [W]) is usually .77 now (from .79, also easy runs). To be expected when adding in a new value (wind resistance). When looking at them comparatively (typical values for non wind vs wind models) I've improved from what I was at 18 months ago.
