This race takes place in the same dock as the Virgin London Triathlon, in the Royal Victoria Dock. Although not like swimming in a lake, the water does look inviting especially on a sunny day.

The water was a pleasant 19℃ last year, and we anticipate temperatures this year to be between 16℃ and 19℃ this year.
