They are very well chosen for their high safety and level interest, so you can just go into them without putting much thought into it.
Sometimes they go a bit too much on the side of safety, making certain transitions annoying, but in general the selection is spot on.
The routes do sometimes go on a bit of gravel, so they are most adequate for hybrid bikes rather than road bikes, although road bikes would be able to to much of them. A more road-bike dedicated possibility is the The National Byway.
Note however that there are many many other local routes which are not in the network, but arguably equally, or more worthwhile.
Their diginal map distribution mechanisms are a bit shitty and sometimes asks you to pay for certain formats, which is hard to understand given that the maintainer of those maps, the Ordnance Survey appears to be public... github.com/cirosantilli/cirosantilli.github.io/issues/61 "How to see the Sustrans National Cycle Network on Google maps?"
Googling "National Cycle Netowrk KML" leads to: data-sustrans-uk.opendata.arcgis.com/ from which we can download the KML. gis.stackexchange.com/questions/216770/how-to-open-kml-file-in-google-maps-for-android then shows how to make that viewable on Google Maps by going through www.google.com/maps/d/u/0/?hl=en on the browser. TODO 2021-11:
GPSPrune 20.2-1 can open the KML however, so that file can't be entirely wrong.
"Ralph Hughes" www.linkedin.com/in/ralph-hughes-501474121 is listed as the creator/responsible of the exports, but can't find his email. Sent an email to gissupport@sustrans.org.uk and he did reply a few days later that they are aware of the issue, and are particularly trying to reach out to Google about it. Great news!
GPSPrune 20.2-1 can open the KML however, so that file can't be entirely wrong.
OpenStreetMaps has them on by default though if you just click "Cycle Map" layer. It is not as incredibly detailed as the Ordnance Survey one, e.g. does not show which side of the street to ride on, but still, is very good.
Jan-Erik Roos could refer to different individuals, as the name might be shared by several people in various fields. Without additional context, it’s difficult to determine which Jan-Erik Roos you are referring to.
Lodovico Ferrari (1522–1565) was an Italian mathematician known primarily for his contributions to algebra. He is best known for solving the general quartic equation, a significant achievement in the history of mathematics. Ferrari was a student of Gerolamo Cardano, another prominent mathematician, and he worked on the problems of solving polynomial equations. Ferrari's work laid the groundwork for further developments in algebra and influenced many later mathematicians.
László Fuchs may refer to a number of individuals, but one notable person with that name is a Hungarian-born mathematician known for his contributions to various fields in mathematics.
Jean-Pierre Serre is a renowned French mathematician, known for his significant contributions to various fields such as algebraic geometry, topology, and number theory. He was born on September 15, 1926, and has been highly influential in the development of modern mathematics. Serre's work spans several important areas, including the study of sheaf theory, cohomology, and algebraic varieties.
Mark Sapir might refer to various individuals or topics depending on the context, but as of my last knowledge update in October 2023, there is no widely known or prominent figure by that name in popular culture, literature, or significant public affairs.
Joachim Lambek was a Canadian mathematician and logician known for his contributions to the fields of mathematical logic and category theory, particularly in relation to the algebraic and categorical foundations of logic and computer science. One of his notable contributions is the development of Lambek calculus, a type of non-classical logic that is relevant in the study of syntactic structures in linguistics and in formal grammars.
Joseph Wedderburn is a notable figure in the field of mathematics, particularly known for his contributions to algebra and commutative algebra.

Pinned article: ourbigbook/introduction-to-the-ourbigbook-project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page.
