Yeah, I've had a play with the site @Yemble made. But even that is no guarantee that the road is any good - common routes can also be locals using roads illegally or slow, safe routes whereas we are looking for speed, gimme what I need...
I've only look at 300k of my route with heatmaps. It exposed a couple of bits I 'fixed' so it's still worth doing. I'll try and get in a couple of hours each night of tweaking what I have. I'm not riding any fucking dirt this year!
