This site seems to have some good answers to your questions. It says
Google assumes a baseline moving speed of around 16km/hr (10miles/hr) regardless of trip distance.
but if you read more you can see there are adjustments to that baseline. For some routes where I've actually compared, I divide the Google cycling time by 1.5 to get an estimate of how ...
The answer given by gammapoint is surely a nice estimate to take into account when looking at Google Maps.
However, as being rather close to Google through Top Contributor and Local Guides programmes (although not being an employee), I can almost surely tell:
We'll never know.
Unless, of course, you get yourself hired in that specific department in ...
Just verified that the 510 can be attached to power while on/in use. It continues to operate. When the external power source is removed, it will give a message to that effect, but does not power down (like the nuvi/car versions do).
Note that you (obviously) have to open the weather seal to plug in power.
Also worth noting, the 510 will go into a different ...
Garmin Edge 800, 810 and 1000 can be charged when exercise is active.
You can use for example power bank or usb dynamo charger (ie. Busch&Muller E-werk, Luxos U light or Supernova The Plug).
It is not recommended to charge anything with usb when it is raining.
Also note that Garmin 1000's plug is in the bottom so cable might not fit when device is ...
I use the Garmin 800 and an external battery with USB output.
The Garmin will keep running for days like that, with no backlight BUT the data recording
cannot cope with a 24 hour bike ride.
On my last two 24 hour cycle events, the Garmin corrupted the activity file at around 23 hours which was somewhat 'annoying'.
I have tested it on distance, with car ...
Inkatlas lets you create printable PDF maps with GPS tracks and waypoints (on multiple pages if needed). You can select a map style with terrain. Smaller PDFs (6 pages or fewer) are free.
Full disclosure: this is my project.
I just completed a 300K brevet last weekend and my Garmin 500 ran out of juice about 2 miles from the end of the 190 miles. 18 hours. I just tried to plug it into an external battery that will charge phones and the Garmin 500, but the Garmin will not operate while plugged in and charging. Note this is the Garmin 500, not the 510.
A friend used an 810 on the ...
Google maps probably treats roads as not having any width, and corners as point turns. Unlike bends, if you zoom in you tend to see a sharp 90 degree change in line on a curve This will cost you the length of the arc you really take.
It certainly omits all the lane changes, obstacle avoidance and similar manoeuvres.
However there is some variation in ...
There is no tool that I know of that solves your problem for you.
The way I solve the problem of finding out what a road is like, is to
use Google maps to find a route.
then use Street View to check the roads at important points. Of course, if the road is gravel, Street View is probably not available.
if the route is not what I want, drag the route ...
Yes you can charge the Edge 500 whilst riding at the same time, and record your ride as well.
Summary: an OTG adapter cable will charge the Garmin 500 using the rear port and allow it to keep recording. The Garmin tests one of the pins to see if it should go into PC Storage device mode, ...
There is a tool I know of that solves your problem: OsmAnd (available for free on F-Droid, paid versions on Android Play Store + iOS App Store).
If the region has decent coverage with properly mapped highway types, the app's offline routing offers a bicycle mode + the option to avoid unpaved roads. Whether the data coverage is good enough in the region can ...
I point out that your comment of
I have (50-559) 26x1.95 tires I should set it to 2089.
Doesn't actually match your table, which says:
50-559 (26"x1.9") 2089 mm
54-559 (26"x2.0") 2114 mm
So the ETRTO number and the imperial measurement are not quite equal. Could be your circumference is closer to halfway between these, or 2101 mm
You can get map files that work on Garmin devices (I haven't tried with Edge) from this site. You can select predefined areas (countries, provinces) of the world you want, or create custom selections of just your area. They generate a map of your desired area and send you an email when its ready so you can download it.
For those still interested, there's a pretty solid map site available now covering the US. Not everything is on there, and you can add more gravel roads as you find them.
You can get a printed map from
Minneapolis Parks & Recreation Board office:
2117 West River Road
Or, you can call 612-230-6400 or email email@example.com and they’ll send you one.
http://wwwdocs.minneapolismn.gov/bike/index.html shows all the bike stuff might be overly detailed.
Apparently its well signposted with maps on the way.
Allows you to draw no-go areas.
Allows you to specify cost for ascents or descents. I’m not sure it’s possible to tell it to completely avoid streets above a certain incline. You could set the cost very high and set the cutoff to whatever you like. Disadvantage of this approach is that inclines below the cutoff are not ...
On my tour across the US, I bought a statewide gazetteer at a gas station whenever I entered a new state, and then threw away all the pages that I wasn't planning on going through. I kept the rest in a pannier, inside a large ziplock freezer bag to keep them dry.
Whenever I stopped for a snack (about every couple of hours), I'd pull out the page where I was ...
as far as i understand it all garmins will charge off any cable/charger combination except for the Edge 500... basically the cable needs to have pins 4 and 5 grounded to earth not just pin 4, so a normal sync cable will not work you need a special charge cable, not content with paying the £12 for a usb cable for this particular use, i made my own by cutting ...
A generic USB cable will have the Edge switch to storage mode but I've found the Garmin cables allow charging whilst using. I have an external battery pack which I used on day-long back-country rides in the alps and could plug it in whilst on a chairlift or at a bar without interrupting the tracking. Arguably I didn't need to but it does mean that when I get ...
Here are a few apps that should be able to use open street map and record GPS tracks:
GPX Travel Map
Windows Phones + Open street map
I know strava requires installation of the googlemaps app to function, but they don't make anything for windows. If you want to use their service of comparing against different users, you can upload data from another app as long as its the right format (which should be possible with any of those open street map apps for ...
The RideWithGPS Android and iPhone apps now also offers this with subscription payment.
As mentioned before, the RideWithGPS website is useful for trip planning, you can customize your cue sheets, save maps and route for offline use, etc.
First do a rolling measure while sitting on the bike to get the speedo calibrated to your actual setup. That's your method B
Then I suggest also getting a proper map and making sure google's scale is correct. They care about navigation much more than 5% errors on inner-city distances, so it might be that their map is less accurate than a proper ...
It seems most of it is mapped on OpenStreetMap. You can use the Waymarked Trails website to view it on a map.
Waymarked Trails - Grand Rounds National Scenic Byway
That has a link to download it as a GPX file, so you could load that onto a GPS device, or other mapping software as required.
Google and other traffic providers like Here (nokia) exchange traffic data, which is crowdsourced from cellphones.
If you're plotted at 5 different points along a know main road and your average speed is 50 km/h there's a decent chance its smooth-flowing vehicle traffic.
If you're riding at a snappy 30 km/h, then it could look like slow traffic. So your ...
RED Circle with numbers 1-5 : Climbs with range of difficulty
RED Circle with numbers "HC" : Hors catégorie or Above Category
Blue Circle with knife/fork : Feed Zone where you grab your musette
Green Circle with white "S" : Sprint Zone
Blue Circle with "km 0" : Just means no break-away is allowed before this point. In essence "the race starts here"
I use Google maps (set to 'cycling mode') and Strava to plan routes. Both try to find the 'best' route between the start and end points but allow fine control of the route by setting intermediate waypoints.
Each will give you details of the route including distance and a gradient profile.
Google maps tends to find routes based on cyclepaths, bike friendly ...
