3 Bay Challenge route


The race starts at Watsons Bay and participants will follow the red route marked “Run OUT” towards Nielsen Park, via the Parsley Bay Bridge (3km).

After the swim at Nielsen Park (250m), participants will run back along the “Run IN” route towards Parsley Bay (2km) for the second swim (350m).

After the swim, the run route goes through Parsley Bay Reserve and towards Watsons Bay (1km), via Gibson’s Beach Reserve, for the final swim (100m).

Total Distance – 6km run and 700m swim

Neilsen Park

Competitors will enter (and exit) Nielsen Park via Coolong Road. Competitors will wind their way around Shakespears Point, descend the stairs and arrive at the beach on the eastern side where they can transition for the swim leg (300m).

After the swim, put your runners back on and head out the same way you came in.

Parsley Bay

On first (Red) leg of run, competitors will run across the iconic Parsley Bay Suspension Bridge and head towards Neilsen Park for the first swim.

On the retrun leg (Blue), you will approach Parsley Bay from Parsley Road. Be careful of the steep decent into the park!

Then run through the Park towards the Beach for a 300m swim.

To exit the park you will run through the secluded and stunning short bushland circuit, that takes you to a waterfall at the head of the gully.

Watsons Bay

Registration will take place in front of the Watsons Bay Hotel, and will open at 6:45am on the day of the event.

The first leg will involve running out of Watsons Bay via Gibson’s Beach Reserve. On the return leg (Blue), there will be a swim (100m) at the Watsons Bay baths prior to finishing the course in front of the Watsons Bay Hotel.

These Baths are an hidden treasure of the Sydney Harbour foreshore, and you could appreciate their beauty and breathtaking scenery as you finish your race.

Kit List

What to wear to the event?

We have seen it all: people swimming in their shoes, running barefoot, and fully clothed or just swimmers.

But the majority of participants run in shoes and their swimmers only. Before each swim, you take your shoes off (as the swims are a circular route) and you put them on again when you take off on the next leg of the run.


Signing in on the day?

Signing in and getting your race number will occur at 6:45 am (race start at 7:30am).

    This was my first time doing the event. I was a little nervous as it was my first swim/run event (although I had done a lot of triathlons before). The route was beautiful, and I liked the fact you ran the furthest distance first. I also liked the fact it was a 'grass root' run event. I would have liked it to have been a swim point to point, but that would have meant having to swim in trainers... I thought the distance was perfect and the three areas (bays) were easy to swim vs. the ocean. There was some confusion at the start regarding the distance - the organiser suggested the first swim was 750mm!! And 1.5km swim in total. I think this was a joke. I was aware this was organised by a group of South Africans and the charity was related to Rhinos. I am a big supporter of charitable givings, but I would have preferred to have supported a charity which would have put money back into South Africa as opposed to repatriating Rhinos to Australia!!!!I would definitely do this again - I am Bondi based so this was super easy to get to. Thanks,

    Great fun, thanks for making the effort to put it on

    Wonderful race. Lovely conditions. A better more obvious finishing area would be great. A good kick off for training for the swim|run event in April 2019.
  • Did the 3 Bay Challenge in 2018

    Had a fantastic race. The bush bashing part on the run from Parsley was a little red hot due to moss. But was great!!!!!
  • Did the 3 Bay Challenge in 2018

    Great local race, friendly people and well organised. Could have done with a few more marshals on key corners but other than that all was great. It was great that the proceeds went to a good cause too and also good knowing that the event organiser are not being greedy and taking the profit as is the case form many events these days.It would be great if this was a series of races and even better if there was chip timing!

    I didn't think the maps really showed the race.
