I’ve been Zwifting for 2 weeks now, really enjoying it. It’s motivating me to get on the bike, especially now there’s snow on the ground :(.
Riding this evening I was having trouble seeing the little icon showing your position on the map which indicates the upcoming road gradient. My eyes are not as good as they used to be. That’s when the idea struck me;
Represent road gradient by color on the map. Roads that are red are incline, the darker the red the steeper the gradient. Downhills can be represented by green, again the darker the green the steeper the decline.
I’m not colorblind, but there are some people, you must allow users to select their incline and decline ‘shades’.
