I found it one of the nicest swims ive done....
I queued up half way back and it took me under a minute to get in
You queue in a line about 10 yds wide, but the swim course ends up at 30m + wide - people spread out and so theres room....
The first left turn is really a gradual sweep left so less congestion.... O think
Any way i am swimming 3 times a week, so ill get battered
