GPS is more accurate than google maps, isn't it? I tried it a couple of times and the gps milage was .3 miles higher than on google maps (for 7.3 mile total commute)

No. A representative 45 minute trainer slog shows me moving .2 miles although I didn't actually go anywhere.

Google maps agrees with distance measured by wheel revolutions within the reporting precision of my Edge 500 - I got 11.77 miles when I mapped my commute on mapmyride.com, and the Edge displays 11.8 miles when I don't detour measured via the GSC-10 speed/cadence sensor.

I run a Garmin 301 most of the time, and I sometimes use my phone for back up, or if I'm trying out a new route, as I find it to be more reliable than the garmin in terms of keeping its connection. I find the battery drain to be pretty horrendous, and while I can charge at either end, I can't charge in the middle of a ride, so it isn't much use for rides over 2 hours :-/

I like the Garmin for keeping track of my total distance, and I like data for its own sake.

I've tried mapmyride, but it crashes my (cheap) phone more often than not. Currently I use Move! Bike Computer, which seems pretty steady and reliable, but is a bit of a pain to shut down sometimes. Maybe I'll try out mytracks (again?) one of these days. I don't remember why I stopped using it -- possibly just because I was trying out different apps.

Hmm. Now I'm trying to import somebody else's GPS track into my phone and I can't figure out how to get it to give me directions. I can get it to put a red line onto my map and I can eyeball if the blue arrow (me) is on the line, but that's about it. Maybe that's a difference between a phone app and a real GPS unit.

For fun I've set up a BikeForums Team on Endomondo - works with Android, iPhone, and can import routes from other devices too.

Anyone can join, all rides accumulate and you can see what other riders are up to.

That URL again is http://www.endomondo.com/teams/1747411

PS: I don't work for Endomondo, I don't know anyone who works for Endomondo... I just like it.

Mapmyride on the iphone. Does a good job of logging the ride. No real complaints with that other then if you are watching it doesn't keep you on the screen, you can ride right off it. That sucks if you are trying to follow a new route that it logged on the Mapmyride site.
It is suppose to be able to show "friends" where I am when its on. A feature I would like to have so my wife can see where I am if I am out on a ride. Never been able to get it to function. That might be available in the pay version but I have not found anywhere that it says that. Major battery suck as well.

I also have a old Garmin GPSV that I have bar mounts for. I like the clean look of no computer wiring on my hot rod and that gives me a way to track speed and routes and it will last most of the day. Unfortunately it is starting to get a little wonkey and loosing reception. think it is on its last leg. Wouldn't mind getting a 700 or 800 series with the cadence and heart rate to replace it it I come into a little extra cash to blow.

For phone apps that live update your location elsewhere so somebody can track you, does that like double battery use? I know your phone contacts the satellite, and occasionally downloads data for the map, but if you are updating a website on your current location, it is also uploading data at some rate too. Is that a noticeable battery hit or does it just fade in with the overall hog that is the GPS satellite connxn.

I've tried on occasion, but to no avail. My phone is GPS equipped but it's not an iPhone, Android, or Blackberry so apps are hard to come by. Found some Java-based apps that should theoretically work, but don't. My phone is a LG Rumor Touch w/ Virgin Mobile service. Maybe its GPS receiver is not good enough; t can be pretty slow to pinpoint my location on the Google Maps app I have. Even if it did work, I'd use it more for non-commuting rides. I know all my commute routes, they're all pretty flat, so my cyclocomputer suffices. Even for non-commuting miles, it's easy enough for me to manually enter my route into ridewithgps.com and get elevation change estimates...

I started using runkeeper on my iphone 3gs, before I leave I throw in my earbuds, fire up stitcher to my favorite podcast feeds, switch to runkeeper hit start, lock the phone and throw it in my pocket.

Every 5 minutes it cuts in over the music/podcast and tells me my distance so far, and average speed.


I'm thinking about getting a phone mount so I could see the info live, but I'm concerned with the phone going flying off the bike as there's some pretty rough patches and a couple curbs I have to hop on my commute...but I would rather invest in a good mount, than in a cycle computer.

Endomondo user here, myself. I started with Runkeeper, but the app is rather flaky on Android. I still like Runkeeper's site and interface in general better, so amusingly I use Endomondo to actually track it then I just export the Endomondo data as a .gpx file and import to Runkeeper. Runkeeper has all my data since I started back commuting this year and I would like to keep a running total all in one place. Hence the export/import ordeal.

I've tried to get this to work as well, but no luck. What I have done recently that allows others to see where I am is I have a small ham radio (Kenwood TH-d72a) that has an integrated GPS. Every so many seconds it sends out a beacon saying where I am, so others can see my currently location/speed. It requires a license, but it's very easy to get

Regarding distance accuracy: I have used RunKeeper on the iPhone to track my runs (and now my bike rides) and it is close but not extremely accurate. GPS can be off by up to 50-100 feet at times, and if you don't have a good GPS signal you won't get as many updates on your location making the device think you cut corners, lowering your distance. If you stay in one spot the jitter in the GPS accuracy can make the device think you are moving around when you're not. Overall it works pretty well but it's not 100% accurate.

Phone GPS's have to contend with phone batteries -- phones are designed to only use GPS sometimes, unlike a dedicated GPS (which usually use larger batteries). But... is that variance really that important to your recording? Especially if you, like me, commute on regular routes that you can define with great exactness anyway? Just asking.

(Edit addition: on fairly-straight rides, like an organized century, you probably won't see much variance. In city riding with lots of meanders... maybe. I did a ~100km a week or two ago through San Francsico and San Jose that when I hand-traced it on Google was ~120km. If it was a race, it would be a big deal... but my own satisfaction with riding was the real goal)

I use Cardio Trainer on my Android. On my 16 mile commute, it is accurate within 0.2 miles. I also have used it on a my group rides and even a century ride. On the century my battery held out for the entire ride with the phone fully charged at the beginning. That was with my MP3 player playing the whole time sending tunes to my bluetooth headset.

Keep these things in mind. Phones do not relay off satellites. They relay off transfer towers and I don't think the towers are actually tracking satellites either so there is just too much garbage to go through for GPS tracking with a phone. I use a Garmin GPSMap60CSx. Other than checking biological functions, you wouldn't believe everything you can track with a true mapping GPS and my batteries last 25 hours.
It was said earlier that GPSs are not accurate. Fact is, they are insanely accurate within about 15 feet or so. The biggest mistake most people make when tracking bicycle or hiking tracks is that they do not reset their GPS to zero AFTER the GPS has fully acquired all satellites. If you start a GPS and just take off, it is liable to make its first reading in the place it was turned off last. I've had tracks where the first way point and the second one are 645 miles apart and only took 4 seconds to close that gap. To fix this, wait until satellites are fully acquired then zero out your GPS. Another way is to check recorded tracks after your ride and look to see if there are anomalies in the first track point or two and simply delete them if they are.
The greatest use for a GPS on a bike is the triangulated altimeter and a barometric altimeter. Then there is total ascent then moving average, overall average, max speed, time sitting still and the list goes on. At the end of the day I get to spill my ride track out on to either a road or a topo map. The uses for a GPS are endless.

Then I get to show you fun stuff like this:

Half right.

Some phones DO have GPS receivers. the iPhone 3GS and up, many of the the higher end smart phones have a GPS reciver built in. My iphone can track me no problem when the phone goes no service. Course once you drive off the last map it uploaded you cant tell anything. LOL

The towers are at a known fixed point so its never been an issue and yes some phones "GPS" is NOT GPS it is triangulated. The GPS reference is a marketing ploy because as you pointed out it is network driven "triangulated positioning".

The network has always been able to triangulate a phone and track it to about 50ft-100ft. Its how the network knows when to hand off the call to the next tower. Often that hand off is forced when a know geographic interference (road running through a valley , hills, buildings, etc) is goign to block the signal is why it tracks you. The system will be programed to hand off the phone in a sequence to deal with the interference.

The e911 is a bit more accurate in some instance because the e911 gear does run a GPS receiver at the cellsite and it communicates with the other e911 gear are the surrounding towers to triangulate the callers position independently of the network.
