Strava Multiple Ride Mapper is what I had used in the past. Doesn't seem to be working right now, though. There was some semi-recent chatter about it on red it, but no new news.

Haven’t tried it, it it looks like fun.

Cool - this works. Maps settings/visibility isn't the greatest, though. This is about as good as I could manage (this is the map of my rides from the last 12 months, minus the stuff in VA) -

If you remember them, you might be able to do something like plot them in Ride WIth GPS, and then export the route file.

I use it for all of my route planning, you can create a route and export it to a bunch of various formats like .fit, .tcx, .gpx, or just print a cue sheet.

I like where I live, but it would still be nice to be able to ride in more than essentially one direction without encountering 8-lane-strip mall hell, bad neighborhoods, tedious MUPs, or all three.

I hear ya. I have a lot of decent riding outside of the immediate metro, but I've gotta get there, first. Fortunately, our MUPs aren't usually MUPs - peds and cyclists almost always have separate paths/lanes - so I can use those, without too much strife, and a handful of suitable roadways to get out towards more open riding. That said, looking at my 1yr map, you can tell that I'm reluctant to ride to the north and the south - maybe there are some decent routes though there, but I'm not aware of them and I tend to think of the areas as suburban hell with roadways that mainly cater to droves of SUVs.

Cool! I've got Summit so I've looked at my heatmaps before, but I like this interface a bit better.

The layer that shows all of your photos is pretty cool, too :thumb:

As I was dozing off last night, I remembered there us a portion of the water line outside the wall, that we need to check. As we were checking it, this morning, a walker went by and informed us that there's no point. There was a big leak a couple days ago. They hope to have it fixed this afternoon.

It's all in old school spreadsheets and memory, although I'm not seeing 2008 - 2010 in the folder with the others. :foo:

About 20 miles end-to-end. Half paved, half crushed limestone.

I just noticed that Strava has an ice skating category.

rjones28 show us your snowshoeing heatmap!

It appears I have no recorded ride data previous to 2012. Makes sense I suppose, I didn't get my first smart phone until around that time.

For the sake of nostalgia I'm looking through my old Map My Ride uploads from when I was in Texas. Some strong memories there, apparently. I'd love to go ride those roads again.

Also, I was significantly quicker back then, when I was still young.

Here's a question that's probably better for the 33, but I don't feel like going there.

Coach gave me an FTP test today. Work stress kept me from falling asleep, so I took 5mg Valium as prescribed once it got late enough that I didn't want to be a zombie today. My FTP was likely so out of date that I wanted to run the test anyway and get something at least closer to the truth.

It had been set at 275. My two 20' intervals were 305 and 307. Garmin, taking a value from my threshold HR, says my FTP is now 270. Everyone's a critic. TPKS took 95% of my best 20' (307) and rounded 291.65 up to 292. My preference is to take 95% the lower value of 305 and round 289.75 up to 290.

I'll rerun the test in a few weeks or a month and see what happens, but does anyone know what effect Valium would have on the test? I assume it can't possibly make it inaccurately-high.

Not a well conceived question for a blanket health attestation form related to COVID-19:

"Have at least 3 days (72 hours) passed since recovery defined as resolution of fever without the use of fever-reducing medications and improvement in respiratory symptoms (e.g., cough, shortness of breath)? (yes/no)"

Might as well ask me if I have stopped beating my wife yet.

LA County has done a better designed study too, just announced results yesterday. They found greater seroprevalence than expected but not as high as in the NoCal study.

However as I understand it they both used the same test methodology and there are some questions as to its reliability.

Have you read the not-yet-peer-reviewed draft of the NoCal study? I have and I was confused by something in their methods section. In determining specificity of the test, they ran it on three groups of blood samples. Two of these control sample groups were small, in the 30 sample range, and the test had no false negatives. The other sample group was larger, almost 400 samples. These were preCOVID samples (whatever that means, Iíd make them define that if I were reviewing the paper! But presumably blood samples collected from a time far enough in the past that the patients from who the samples were taken could not possibly have been infected with this novel corona virus). In this larger sample, they had 4 positives, so a false positive rate of 10.1%. Yet they calculate their test specificity to be something like 97.7%. Seems to me like thatís too high of a specificity for a test that had a 10% false positive rate in the largest control group tested. But Iím bad at stats.

Since their study group was something just under 4000 people, if we apply the 10% false positive rate to that group, youíd get 40 positives. The study subject group had far less positives than that- ie *all* the positives in the study sample could have been false positives. So itís seems like a hugely flawed study to me, it will be interesting to see if it makes it through review.

Also the interesting thing with their case recruitment being through FB ads. That seems to me like they really could have biased their study sample towards people who thought theyíd been sick with COVID but couldnít get tested. Those would be the people IMO who would be most motivated to seek out testing, and the way FB works itís easy to be connected to likeminded people in the same boat as you. So I could see that the study participants were skewed towards people who suspected theyíd had the disease.

Then did you catch the fact that signing up for the study was first come first served, and if you got in, you were allowed to bring a child from your household. When you look at the number of children in the study, you realize that around 50% of the study samples were from two people in the same household. So if youíd already selected inavertently for COVID suspects, now youíve just doubled your expected number of positives because youíve included some many in-contact samples from the same household.

Bottom line: I think that study is such as mess, or at least it is as I can understand it fromhow itís written now, that it may be impossible to get much of anything out of it. If you havenít seen the released early draft of the study, I can link to it.

Not in the medical field (engineer) but wanted to give you a heads up on the math. 4/400 is 1%, not 10% so the 97.7% accuracy makes more sense. Completely agree with you on all the other conclusions you have drawn about the questionable value of the study.

Tell me about it. At its worst RA has been like aging another 40 years. There were a couple stretches where I needed support handles to sit on the freakin' toilet. :rolleyes:

Benzodiazepines enhance the activity of gamma aminobutyric acid (GABA) an important inhibitory neurotransmitter in brain and spinal cord and present in many of the reflexes loops that inhibit motor output. That's why it works as a muscle relaxant. As a card carrying neurophysiologist, I would be willing to bet it's bad for your FTP, if anything.

Doh.


In addition to being bad at stats, I'm also bad at basic arithmetic.

Thanks, thatís the direction I figured it would shift things. So I can go with 290 for now as a reasonable floor for reality (more reasonable than 275 at least) and get more accurate TSS. Then hopefully next tine around will be clean. Hadnít needed it in two months and then itís the night before the test work kills me.

Thanks again.
