Congratulations on creating trailrouter! This is one of the most unique and useful side projects I’ve seen in quite a while. I had a lot of fun looking at the various suggestions it offered for my neighbourhood, and I could see how this could help people enjoy their neighborhood a lot more.

If you have the time, I’d also love to read a blog post (or even series) explaining how you built this. Your answer on the Graphhopper forum was very clear and makes me think that a more detailed version could be super useful for a lot of people.

Nice work!

Thanks very much for the kind words! I wasn't sure if others would find the technical details of this topic interesting (it's my first foray into GIS work), but it sounds like they would, so consider a blog post in the works.
