In reply to harrowgrah:
You can use the "Find Crags" section of the logbooks on here to do this.
From the dropdown menu on the Logbooks tab (above) select "Find Crags"
Once on Find Crags page enter climbing style you are after i.e. Sport
Enter your location (Town or Postcode)
Choose radius of your search e.g. 75 miles
Hit search!
You'll get a list of crags (click to open up details on each), they will be listed nearest first, but be aware some may include only a single route with a Sports grade (rather than being predominantly Sports venues). There are some pretty obscure "crags" in the database, especially in areas with a lack of Rock such as the West Midlands.
