is there an app for showing gradients of hills (google maps etc)?

was just wondering if there is an easy way of looking for good hills on online maps that will give the gradients etc so that i can find some steeper hills to ride (or attempt to ride anyhoo) both on/offroad.

i live in devizes wilts and have heard of some steep hills that are 25% (road) near bath but have no idea where they are.

if there was an app that would show you whilst looking at the map, it would be great as i could then see how close to me they are to plan a ride etc.

thanks

ps i have a garmin edge 520 plus gps but have never yet plotted a route on it (as no idea how to yet/told you i am a numpty).

Just look at an OS Map. From memory > on a road indicates 14-20% and >> indicates 20% plus.

There’s always the 100 Greatest Climbs books, app etc.

edit: and as above, go looking for double chevron climbs on OS maps.

This app might help

MapOut, The Best Smartphone Mapping App – Just Got Updated!

I think it colour codes plotted routes by Gradient

In Bath Thomas Street is steep, Lansdown is a long drag up and out (especially when laden).

Pop over to Stroud, as an early “stay local” lockdown challenge I managed 28.55 miles and 7168′ with no hill repeats.

The app OsmAnd is a mapping app that shows contours and paths.

streetmap will drill down to OS level, I use google maps and streetmap side by side

but really for route planning our club has a club sub to Ridewithgps that has a profile window, so you can see what’s on the route anyway

I just use bing.com/maps then select the OS view in the top right, then you can plot routes and so on, or just cheat a bit and look for folk who have already done files that they can share, as above, the likes of Bath have the 6/7/10 hill challenges, i well remember Brassknocker from when i had to commute from BoA to Foxhill in Bath, or Shaft Road, but these are well used car routes.

Out by Devizes you also have the steep stuff heading towards the plain, you could do a lot of ups and downs running from Market Lavington to Westbury and back!

Try Draycott Steep over near Cheddar, that’ll clear out your lungs.

At risk of asking an obvious question, why don’t you use a map (or appropriate software)? Contour lines will tell you all you need to know.

My guess would be viewable area, os etc are great if you know where you’re looking roughly but it you’re looking town or county wide it’s either wide scale so no contours or a lot of scrolling about to find what you’re looking for if you’re in a mobile screen.

As for an app for that, I can’t help sorry, though you might find strava heat map a good place to start

Try Draycott Steep over near Cheddar, that’ll clear out your lungs.

I can definitely vouch for that one, the middle section is evil, ~0.5 miles of ~20%! By luck rather than planning, I managed to cover the slightly extended version in Sept ’20 during our caravan hol in Burnham On Sea https://www.strava.com/segments/9770445

Another nasty climb near Devizes I’ve done is the Kingsettle Hill/Tower Road climb up by King Alfreds Tower https://www.strava.com/segments/2986434 . Small section ~20%, it was quite challenging having just done a VO2 max effort up Gare Hill.

The only climb I’ve done that I reckon is harder than Draycott is Ffordlas/Hillside starting just up the road from Prestatyn train station and heading towards Gwaenysgor. 33% gradient traffic signs might be a bit overhyped, but it’s bloody steep in places, had to meander across the whole road width just to keep moving and not put a foot down on a ~17Kg hybrid after I had mechanical on my road bike.

If you draw routes in Komoot, you can get a graph of altitude and then hover over the graph to see gradient.

You can actually look for routes in your area if you don’t want to create your own.

They can also be uploaded to your Garmin.

FATMAP. Is what you are looking for. Its normality great for planing snowboard and ski off piste. Used for mtb as well

bing maps has os maps once you zoom in a bit, then just hunt for grid lines that are close together.

Yeh it’s called map reading…..

There’s a slope angle layer on Outdooractive but turns out it’s just for skiing areas.

if your route covers any strava segments, Veloviwer is very good for this
