UK Urban League (2015-01-25)

4-5: I turned one path too soon in the small alleyways. 13-14: a bit off line from 14.
21-22: lost concentration and left control in wrong direction. Then I could not work out the best route to the post. I did not see the route to the west and underneath the bridge. 24-25: I thought that 25-27 were on the top floor of a car park but I was not sure of the control description for 25 so checked that it was not on the ground floor en route. 3rd place
