    You'll need your numeric Strava id to use it.

    LOL.

    Click on that link, enter Sigurd's ID, 192460, and when it warns you about there being too many rides, select the most recent 100 rides, and just watch what happens. Dang!

    Two more super cool Strava tools from the same site:

    1) Strava KOM Notifier (requires registration): Receive emails every time there is a change in the Top 10 of a segment you subscribe to.

    2) Strava Segment Analyzer: Shows the historical development in Overall #1, #2 and #3 for a segment as well as timing history.
    As an example, look at the development for the top riders in the "Adams Ave. Mini Sprint", a heavily contested segment amongst SDBikeCommuter members (and presently KOM-ed by one of us).

    The Strava iPhone app was updated a few days ago. Not sure if there were any changes to the functionality of it, but the update supposedly contained several bug fixes: I've had the app crash / lose signal quite a bit that caused full ride data loss, so any fixes are good news.

    -----

    Many pundits have recommended using the Cyclemeter app to record ride data on grounds that it purportedly drains the battery less than the Strava app, and then upload the resulting GPX file to Strava. I have used Cyclemeter in the past and it has never crashed or lost signal for me - which cannot be said for the Strava app.

    In order to test, I used Cyclemeter to record a ride today: For 4:50 run time, plus 3:00 standby time, Cyclemeter used about 50% of my iPhone 4 battery life (iPhone also used for other tasks during the ride). This seems to support a claim that the Cyclemeter app drains the battery slower than Strava does.

    The one downside to using Cyclemeter: You need to email yourself the ride GPX file (this functionality is built right into the app) and then upload it to Strava.

    Cyclemeter has been around for a while, it's reliable.

    What I would love is a turn by turn navigation tool that I could upload GPX files into. I use Motion-X GPS for this, but it's not turn by turn ... Just a decent map.

    I did another test using the Cyclemeter iPhone app to record a ride (and then uploaded the resulting GPX file to Strava): While occasionally also running other services (GSM, Bluetooth, WiFi, 3G) and apps, the battery was drained by 65 percentage points (from 100% to 35%) with Cyclemeter recording for 4:30, plus 4:00 standby time. The GPS (AKA "Location Services") was turned on for the entire 8:30 testing time.

    From my observations it seems like the Cyclemeter iPhone app is less power hungry than the Strava app.

    Today I did a CCW loop around Mt Soledad. Got a good time (for me) on Santa Fe and the Rose Canyon bike path (going north) largely because right as I turned onto Santa Fe, I noticed two cyclists coming behind me (from the Bike Warehouse). So I had them in my mirror the whole time... if they started catching up, I would lift the pace, but was unable to drop them. Anyway, they really pushed me, and I was relieved when I turned left onto Gilman that they turned right!

    So when I looked at the ride on Strava, it said I rode with "one other person". Really? So I looked at this other person's ride today, and the only overlap was that Santa Fe + path segment, and we had the same time, to the second. So I contacted him and thanked him for the push. Turned out he was riding with his wife. LOL... a "Strava connection"!

    That thing swivels in two directions - so you generally make it horizontal and minimal drag becomes negligible, not to mention that the drag of your whole body is behind it anyway.

    Ambient noise makes it difficult to hear a phone in my jersey, and vibrate does not alert me reliably when riding. But right under my nose I see/hear it.

    On your Dashboard, you can see what type of device other members use to record their rides: I think you will find that an overwhelming majority of Strava cyclists use a Garmin (or in some cases dedicated GPS units from other manufacturers).

    Personally, I now only use a smart phone for shorter rides and a Garmin for everything else. Even when I record with my phone, I prefer the Cyclemeter iPhone app to the Strava app as I have found that the Cyclemeter app is both less crash prone and less power hungry than Strava. So I no longer use the Strava iPhone app at all.

    Here's an alternative:



    It's a 5000 mAh Li ion auxilliary battery, next to an iPhone 4 for size comparison. It weighs 6 oz. I got it for about $25 on Amazon. iPhones and Android smart phones have about 1400 mAh batteries, so this should comfortably triple the battery life. I haven't tested its limits yet, but with this I should be fine using my Android phone w/Strava app even for longer rides (if I ever go on one!). As for the stability of the Strava apps, I have not tried the iPhone app, but have not had any problems with the Android app on my HTC phone except for when my battery was very worn. I got a new battery and I'm fine now. Strangely, for the first few rides after the battery change, it took forever to get a GPS lock when I turned on the GPS and opened the Strava app. But it's fine now--maybe something got reset when I removed the old battery and installed the new one.

    As for carrying the phone in a jersey pocket, I'll continue to do that sometimes for road rides, but for mountain bike rides I will get a bigger seatpack and carry it there. If you need to roll out a fall over rocks, the jersey pocket isn't a good place for a phone.

    Sure. It will hold tons of rides and Strava (or any other online repository like GarminConnect) will mark all the rides that haven't been uploaded yet when you plug in. Unless you are looking for navigation features, check out the 500. I get 18 hours of battery life without, and much more with, an extended battery. Avoid the premium heart strap, though. It is a dud.

    Well that is the issue, if I didn't need navigation the 500 would be a no brainer. But I sort of want the Nav, so it'd be $450 since I've already got ant+ stuff and I consider myself fairly tech saavy and would use the OSM. Since I've been moving around a ton lately and I just like having bike bling, I'm thinking Nav is required so I emailed Garmin to see if they will be launching the 900 in the immediate future, I'm not sure if they will respond, but you never know.

    I got the Garmin branded Power Monkey but most of the rando people use Gomadics, which are much cheaper. You might check to see if you can get the correct tip for the one you already have. Also, you can't charge while it's on the Garmin o-ring-- if you want to do that, you need an aftermarket mount like a Barfly.

    We're talking about two different things, I think. The port on the Garmin is not accessible if it is mounted on the stem with the o-rings. In order to charge while using the device, you must have the current firmware. You can check that in settings and then confirm on the Garmin site. I got mine last winter and it already had the updated firmware installed.

    I have observed the exact same time with people I have ridden with - they do two laps, and get the lap time recorded as the time it took them to do two laps. Weird.

    I think maybe I did three or more laps that time I got my best time - don't know if that will resolve the issue for you, but worth a try!

    I suspect the GPS inaccuracy really plays a role on such short segments. It might not have enough data points to realize you went around twice.

    Speaking of GPS inaccuracy, what about the QOM? :15? 28.4 MPH? Really?

    Serge2:Speaking of GPS inaccuracy, what about the QOM? :15? 28.4 MPH? Really?
    I suppose it is possible. But when riding around at 5mph less than the QOM speed the centrifugal forces were strong enough that it was exceedingly difficult to hold the line.

    OK, I got curious. All non-geeks please skip this. Here's a snapshot of my 7/1/2012 ride around the Soledad Cross, viewing the exported GPX file in Google Earth. I rode up around the monument, on the road, in the normal counterclockwise direction, rode hard until I had completed the lap, did some extra to make sure I "tripped the wire" for my lap time, then doubled back on the road to get a drink at the drinking fountain. Then I rode out on the grass. You can see the deviation in the data points from my actual path, and I would agree that is probably why the lap isn't recognized properly. If you view the GPX file in a text editor, you can see that the data points are 3 seconds apart. If the arrows represent consecutive data points, then I did the lap in about 15 seconds, which would roughly tie the QOM. However, I am not sure that the arrows represent consecutive data points. The track in Google Earth appears to have a "run time" of 100 minutes 19 seconds, while Strava recorded the ride at 55:43 total time (in agreement with manual inspection of the file) and a 44:20 moving time. I don't know where the 100:19 comes from.

    - Could it be that Google earth has incorrectly added the total time to the moving time to get to the "run time" (55+44~100)?

    - If the arrows represent consecutive data points - shouldn't there be several arrows bunched up together around the drinking fountain?

    - In order for a segment to be recognized as completed one needs to have hit at least 75% of the data points in the original segment: Could it be that there are so few and spread apart data points in one lap that only after having made two (or more!) passes that you are deemed to have met the 75% requirement?
  42.  
    Sigurd-

    Many good points, especially the point about bunched data points around the drinking fountain. Don't think we're looking at 44+55 since the 44 is calculated by strava. Clearly I don't know how tracks work in Google earth. I will look for another gpx viewer or do some research on Google earth.
  43.  
    This is what it looks like using the "Google Maps detailed input" link on gpsvisualizer.com, with 2000 pts per track (i.e., more than the number of points in my file) and a tickmark interval of 1s (which means 2/3 of the displayed points are interpolations of the data in the file, which is recorded at 3s inervals). With this visualizer, you can hover over a data point and display the time stamp for that point, and then use this info to manually calculate time intervals. Alas my time of 23s on this day means I am no match for the Queen of the Mountain (15s) or the King of the Mountain, Sigurd (19s). I am happy to see that the exported .gpx file appears to contain all of the data points; i.e. Strava stores and exports the raw data, not an edited version. But I am still a bit confused by the pattern of sharp turns, which do not occur at intervals that are multiples of 3s.

    (For anybody unaware of this: One can achieve a higher level of zoom on Strava Google Maps by viewing in Satellite View than in Map View).

    Below is a Satellite View screenshot of your 7/1 Victory Lap, Shady:

    Photobucket

    It seems like Strava did not capture you crossing the finish line, but instead continued to time you while making a U-turn and rolling back up to the drinking fountain - and only then finish your lap. Even though the Victory Lap starts and stops near the drinking fountain, it would improve your chances to assume it starts at 3 o'clock (as seen from the west) and stops at 9 o'clock and push full power through that one and a half lap.

    Ultimately, as your recorded e lap is so short it only consists of only four or so datapoints (it looks like a quadrilateral), I think the Strava algorithm cannot reliably match it with the original segment lap.

    Here's a screenshot of the official Victory lap - for some reason it has twice as many datapoints as your (is there a setting on your GPS defining data capture frequency?): No wonder Strava is unable to match the two, perhaps?

    Photobucket

    If so, it may be that making several passes around the fountain will increase your chances of getting your lap matched and thus timed correctly.

    There's a way to download a GPX file of someone else's Strava ride. Just copy the URL for the ride you're interested in, then paste it in this page:

    http://cosmocatalano.com/strava/export/

    (edit: I see this was mentioned earlier in this thread, but I just found out about it)

    I did this for my ride today. I knew I would be in OC with a couple of free hours today, so I searched in Strava with some road names as keywords and found an interesting looking route that someone had ridden six months ago. (Note: the cloaking function remains in the downloaded file; i.e. this doesn't bypass the privacy settings, which is good.) I guess I could have imported it into a maps app and used my phone, but instead I used gpsvisualizer.com to generate a printable map, then took the paper map with me for the ride. I didn't see a good way to print a map of a route directly from Strava.

    While looking for rides in Orange County, I also came across this site:

    http://www.geoladders.com/routes.php?search_id=15

    Looks like a good resource for archived rides.

    bikingbill:What do people do when taking the Ferry? I left Strava running, so it kinda messes up your time. But how does it deal with a start/stop that doesn't happen at the same location?


    This is how I think it works, based on my experiences with it: If you leave the GPS running on the ferry (or the car, or the Concorde), Strava will not know any better than to assume you're still cycling. Many cyclists forget to turn off their GPS on the ferry - somebody even created Strava segments in both directions.
    :face-monkey:

    If you stop your GPS at the departing ferry landing and restart it at the arriving ferry landing (or any other stop/start points) Strava will:

    1) NOT include the stopped distance in your stats (although I think it might incorrectly count your elevation change - but this wouldn't be significant for a ferry ride, of course).
    2) Your stopped time will be counted under "Elapsed Time" but not under "Time" -- or included in "Avg. Speed".
    3) On your ride map, Strava will draw a straight line between stop and start points.

    Based on this, I would recommend that you stop/start your GPS any time you move between two points while not riding your bicycle (or running or skiing or whatever activity you're taking part in).
