Granted, in a few weeks I hope that the entire route is faster than what the partial was, but then what if I only do part of it in the future? Anyway, seems like an odd quirk
That's a phone-based GPS issue. Quite a few posts about it on various tracking software forums. Phone GPS antennae and software aren't at the same level as a dedicated GPS unit's. (Comparing two rides/runs taken with a phone and a Garmin running at the same time will show pretty different tracks. The phone will be a smoother line, but, in general, the GPS will have a more accurate display due to better reception, higher sampling and better algorithmic accuracy.)

I really don't need another gadget and it's too bad that there's so much stuff going on inside that thing. A tiny cam, built into the tail flasher with a shock sensor and a 5min loop recording would be enough. Have it turn on/off when you activate the flasher, then turn off and preserve the footage if the shock sensor detects a hit. No need for all the frippery. (ANT+ compatibility, video display, etc.)

Did it!

Woohooo! Just uploaded my first Strava run. I walked across the office parking lot at an average speed of 3.4 mph, achieving a top speed of 3.7 mph.

Beat that, you fuckers!

That was with a Garmin The problem is, one day I only did part of the trail, the next ride I did the whole trail. The Strava segment is the whole trail. Strava says my partial lap is the fastest full lap that I have ridden. For some reason, I guess since I rode most of the trail on the partial day, Strava is thinking I rode the entire trail. Even though the partial ride was 5.1 miles, and the full was 6.2 miles. The data from Garmin is correct, the interpretation by Strava is not in this case.

That's going to add precious seconds to my times!
No worries, the app is pretty intelligent. It tracks moving time and stopped time, and uses some kind of magic to figure out average speed. I have forgot to sip the app when i got hone before, and it showed the ride time a very close to a typical ride once i finally hit the finish button.
I have noticed it on my phone immediately after a ride that some of the data is way off, even when initially uploaded it may show errors, like i managed to drop to sea level and then back up to the real elevation within a quarter mile giving my total elevation gain an extra 1000 feet. But within a few hours, it is showing a corrected, believable figure.
Now last nights ride, it managed to cut me off right in the middle of one achievement, and show i rode cross country and reconnected my course right after the start of the next, not giving me any data for either one.

Ah, I misunderstood. Yep, the partial segment thing is also a glitch. I've seen that on some of my rides as well. (I'll get a time for an entire lap of a nearby park when I know that I only rode about 1/3 of the way. It doesn't seem to just hand out a KOM for that partial, though. )

That's what I run. I used to ride the 20's, before I knew better...

i was reading a year or two back, the LD racers, like the grand tours, are running larger tires now, as big as 27s/28s, because the new tires are just as light, and have excellent rolling resistance and a smoother ride.

when I rode road bikes 30+ years ago, I used to run a skinnier tire in the front and a fatter one in the back, but these were Clement silk tubulars (we called them sew-ups back then), so I don't know the exact sizes. IIRC, I ran a Campianto(sp?) Del Mundo in the rear which was probably about a 28, and a Criterium or ?? in front which was a 21 or so or a paris-roubaix which was a little bigger and tougher, maybe a 23 (just guessing on the sizes). I think sometimes I ran p-r in rear and crit in front, heh, especially when I was running lighter 'blue label' rims instead of the sturdier 'red' rims. for touring with front/rear panniers, I'd run the del mundos on both rims.

I was even pretty good on roadside sewup repairs, when you get that 3rd flat on a trip. hah.

[typed while sitting on my ass feeling like crap, broken right foot (car accident) elevated on ice because I had surgery yesterday]

when I get my foot back, I *AM* going to beat myself up into shape, I have to lose like 50 lbs, being fat (230 lbs) sucks. my new ebay 700c hybrid is fedexing its way to me now. what really sucks is, the ER and the doc showed me as having high blood pressure... damn, I used to have LOW blood pressure.

This is my primary ride of late, an Electra Verse...



We take it 6.2 miles to the Y, then I do a 45 min spin class, then we ride home. Usually we're able to do it 2-4 times a week. The last 1/2 mile is uphill, spiking to 10% near the end. If I figure the spin class at 12 miles, I'm usually getting over 100 miles a week in, but only about 30 of it is recorded with my gps, and that's only if I take my "real" bike out on the weekends... I may have to look into the Strava app for my phone...

I don't know what the whole rig weighs with the boy on board, but it's gotta be around 50 pounds. It rides nice though and the long top tube gives plenty of room so the seat doesn't hit my knees.

Add an option for bluetooth capability to be able to stream the image to your phone and I like it.

Sinus infection is kicking me down. I'm support to ride an easy 60-miler tomorrow and thought I'd drive to the ride and cut the distance in half. Now, I'm thinking of skipping it the ride in order to get better quicker.

I not only have one, I've corresponded with the founder quite a bit.

It's a neat unit, but still needs some software refining. Battery life isn't great, either, but I haven't tried turning down the recording resolution to see if that helps (it may, since it won't be working as hard on compression). If you ride three hours or less, the battery is fine. If you're training for longer stuff, it may let you down. I've also had some trouble getting ANT+ data to display right, but I haven't worried much about that since I can't live without my Edge 800 anyway.

And for anyone that cares about Leadville, I've been updating my blog pretty much daily. Today's features data from a Powerline climb as well as a picture of my nearly taco'ed rear brake disk. Ugh.
