Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

I don't like the "taller" activity format. I have to scroll more and I hate that. But the larger photos are kind of nice. I wish they would move the crap on the right hand side to be with the crap on the left hand side and use that extra space to reduce the vertical height of the activity. The "activity feed" changed today; the "user profile" had minor changes last week. I like that I no longer have to scroll over the goal bar to see how many miles ahead/behind I am on my annual goal.

The GPS chips in phones have gotten really good at fixing a static position-- most new phones can get within a few meters. And their refresh or polling rate is 1hz, just like pretty much every consumer GPS device there is (there are some devices out there with 5Hz up to 20Hz rates) so they have the capability to be every bit as accurate as a dedicated GPS device. But the power requirements of GPS is one of the highest drains in a phone-- just behind the screen-- so the programming (and sometimes the hardware itself) quite literally cuts corners in an effort to balance GPS use and battery life. Depending on conditions, reported position can fall to the minimum accuracy of the chip-- 300m. This is why GPS is not great at determining speed. Even on a bike at 30mph, the GPS refresh is occurring once every 44 feet. So if a segment is a scant 0.2 miles long and the phone user gets the start/finish positioning "bonus," he will cover 8% (or more) "less distance" on that effort. The start/finish of a segment might happen to fall in the middle of a refresh for the GPS chip, so the rider is a full second (or more, based on the accuracy of the position correction) into the segment before the phone records that he's there. This is (in my estimation) why I see segment efforts with an average speed higher than the max speed.

Apps like Strava can't override the phone's OS instructions for the GPS, so you get inaccuracy. I've seen some files with insane zig-zags that cross over entire neighborhoods, and pick up segment PRs / KOMs on parallel streets to what the ride was actually on. This isn't as good, but it shows the less precise position correction of a phone GPS compared to a dedicated device. Strava Android App on the top, my 520 on the bottom:


Thanks for the elaboration!
So it seems one could luck into a good time, so to speak, when using a phone app to record, but it could work the other way too, couldn't it? So perhaps select results are not so reliable, but on the whole they are reasonable indications of ones placement if one consistently obtains the same time. That's good enough for me. It's not like I'm going to capture a KoM on anything that matters.

The funny thing is that you might capture a short segment without even trying.

There's a popular half block slightly uphill on my commute where the KOM was around 30 mph in 20 sec.

A school girl captured it on her hybrid and iphone from all the serious riders without trying.

Of course someone flagged it eventually.

Some segments are clearly done one way or the other, or multiple. Knowing more than gender and age would be a very nice feature.

Well, they done did it again-- the Strava Dashboard page is now revamped, but all other pages unchanged. Everything on the dashboard moved from the right margin to the left margin, and I don't know how much I care for it... seeing as everything else is still on the right. Also, that same disconcerting font change is there. Who updates a UI like this?

Yea - I can't spell. On the other hand - I didn't type that. Too many technologies helping me.
And always some double entendre, but mostly bad spelling.

It could also be I tend to post after drinking fine wine. But you know what I mean.

Your spelling is perfect, it's just that you're spelling the wrong words!

know = no, hear = here

I thought you did it on purpose (porpoise!), so I chuckled.

Sometimes I do, and sometimes I don't.
Hear was a mistake. Know was not. I corrected it anyway as I'm self conscience and it didn't work.

I make a good living for a guy my age working in tech. I should love Strava. But, I don't.

If drone racing and MLG can be legitimate, sponsored events, Strava can absolutely be a sport. If it doesn't fit inside your current definition, you may need to redefine. Saying that because Strava isn't risk-filled, shoulder-to-shoulder racing makes it no less legitimate than TTs or Tris. I mean, at the end of the day Crossfit is a competitive sport, and it's just a bunch of people working out wrong.

Strava is all that. You talk smack on social media, get all the big kids out there and spank them with someone with a camera recording it.

It is an art. You just have to no how to do it.

Oh yes. Social media. How could I forget? And, this being just another tool we use to inculcate narcissism in our lives. Like we need such a thing. Technology is a double-sided sword, my friend.
