How does the event work?

Here are a few tips on how the event flows and what to expect:

  • Turn up at the Event HQ either the evening before or the morning of the swim and we’ll give you your race pack with swim hat, timing chip, and wrist band for your allocated bus shuttle time.  
  • Wetsuit swimmers can get changed at the Event HQ with baggage storage available. 
  • Non wetsuit swimmers take their bag with them to the start, with baggage transport to the finish.
  • You board the bus according to your event start time (based on your predicted mile pace).
  • We have a large marquee at the start for shade (!) or rain and a relaxed atmosphere to prepare you for your full length of lake swim. A full event briefing is given to you at the start of the swim.
  • As you set off, water safety kayakers and support boats are there to look out for, and support, you.  
  • Mile markers are positioned to help guide you down the lake with feed stations starting at mile 1.5.
  • You can stop for a drink at the feed stations or swim past and continue on your swim for the 5.25 miles. 
  • At the finish, your medal is placed around your neck, a warm drink awaits and buses are on hand to shuttle you back to Event HQ.  
  • Non wetsuit swimmers can change at the finish area and wetsuit swimmers can use the changing rooms and showers at Event HQ.
  • Although this really event is about taking part and completing the journey, we do have prizes for the fastest in each age group for both wetsuit and non-wetsuit swimmers. 

What pace should I put down when I enter? 

The entry system asks for your mile pace, if you don’t know, then go to the swimming pool and time yourself swimming hard for 1 mile. Many people tend to underestimate their mile swim time or add a slower mile time to ‘play it safe’. This creates problems as you will be swimming with a group and the water safety team cannot separate for individual swimmers. In simple terms, if you add a time which is too slow for your ability, you will be asked by the water safety team to slow down on the day and your finish time will be affected.

If you need to change your mile time before the event then simply log back into the entry system at and you can change your pace up to one month before the event. On the day the more relaxed pace swimmers (65 min/mile pace) start first and approximately every 40 mins a slightly faster paced group will enter the water. You’ll have a much better experience during the swim if you put down an accurate swim time and you are grouped correctly. 

What time does the event finish?

Swimmers will arrive at the finish between around midday and 2.45pm and prize giving will be held as soon as possible after the last swimmer is out of the water, back at the event HQ (n.b. for 2020 No Prize Presentation but instead Prizes will be posted and emailed out).

Is there an age limit?

Competitors must be a minimum of 16 years old on the day of the event. There is no upper age limit.

Is there a cut off time?

We have a cut-off swim time of 65 minutes per mile, so with the staggered starts we the last swimmer will be out of the water by approx. 2.30 pm. With the sweep boat making sure that everyone is out of the water by 3pm, which is normally plenty of time for even the most relaxed swimmers taking in the view and having a chat!

When does registration open?

Registration will be open on Friday evening from 1600 – 2000hrs, and on Saturday morning from 0700hrs, to allow the early swimmers chance to register on either day.

Can I swim with a friend?

If you and your friend swim at the same speed and you have added the same estimated pace into the registration system, then you will be placed in the same start group. However, we recommend that you don’t try to compromise your own pace to swim with a friend. We have found that inevitably one person is faster than the other, which can be frustrating for you and cause the faster swimmer to get cold waiting for the other swimmer.
