We welcome feedback about the guide. The online version is designed to be constantly updated as new routes are added or information is corrected.

We are most interested in:

• New routes
• Corrections to route descriptions, and topos

Comments about grading and starring will be taken on board, but in the end the editors have the final say on subjective matters.
