Like Streatham, it is unusual in that the Treble and 2nd follow one blue line, which is 40 changes long, while the 3rd, 4th and 5th follow a separate blue line, 60 changes long. The plain course thus contains 120 changes. Watch out for all the wrong leading (backstroke and handstroke).
Treble and 2nd | 3rd, 4th and 5th | All together! |
