Thoroughly enjoyed the event and the atmosphere of the day. This was my first Open Water Swim event and all the staff/marshalls were friendly and helpful in this regard. I felt confident in knowing where I needed to be, and when! My only concern and disappointment was that the 3km swim was actually closer to 2.5km. I was not the only swimmer to emerge with a Garmin that showed a distance that fell far short of the advertised 3km. As this is my first swim event, I'm still delighted with 2.5km but it's a shame that it wasn't the advertised distance.

This was the best event I have done this season. I did the 1500 swim - the water is beautiful the organization flawless - the volunteers lovely and the venue- well if you don’t want to swim in the Olympic lake are you really even a swimmer ? Hard recommend
