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 ...
The best solution: Have a navigator with you, who has a handlebar bag with a map sleeve:
Otherwise I almost always ride with a handlebar bag, which has a transparent map sleeve on top. Both options on the same picture:
Two maps possible, in case you want to go different routes
On trips without ...
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 ...
You could use ridewithgps to build your map. It allows you to drag waypoints off the main route and re-routes (can be used without auto routing as well if you prefer). You'll have to pay if you want to print from their site. However, you can print a cue sheet free or export the saved map in GPX or TCX format to print with another application or website ...
Zip tie + Binder Clip on Stem clamping to a 1 Gallon Ziplock Plastic bag with properly folded map inside. Alternatively, if that's not secure enough, use 2 binder clips + zip ties on the handlebars.
I found a similar DIY setup using velcro wire ties

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 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 ...
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 ...
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.
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 ...
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.
If you have an iPhone or an Android phone there are various free options, some based on OpenStreetMaps, but even Google's own solution is excellent. For google maps you can download areas to store locally (for those areas you know you will have no connectivity) and it is free!
I'm playing a lot of Ingress at the moment, which requires 10 - 20 hour stints ...
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
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 ...
You can get a printed map from
Minneapolis Parks & Recreation Board office:

Or, you can call 612-230-6400 or email firstname.lastname@example.org 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 ...
Granted this answer is not for everyone, but it is simple for tandem riders. As the helmsman/captain I wear a Camelbak with elastic webbing which holds the OS map conveniently in front of the stoker (I have a photo somewhere). I get funny looks when I walk into shops with a map on my back, though.
If the scale is large enough it can be read while pedalling, ...
Correct me if I'm wrong, but Google Maps ALREADY allows for point insertion, by means of "breaking" one segment in two.
Instead of using the navigation directions, click the "My places" button in the sidebar, then "Create Map". The drawing tools appear on the map:
While editing a path, if you hover over a segment, the midpoints of each segment appear as ...
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 ...
