It's actually Meadowbank Velodrome in Edinburgh. It's been getting a lot of publicity recently as it's scheduled for demolition. See http://www.savemeadowbank.org/ for further info.

That's my photo, part of a documentary project I did entitled "Regulation" on Scottish sporting venues. Have a look at http://cargocollective.com/albieclark#6809 or download a lo-res version of the book here: http://albieclark.com/regulation/Regulation_Albie_Clark.pdf (7.8mb).
