How does the event work?

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

  • Arrive at Event HQ at John Ruskin School in Coniston 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 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 Mile Swim Time should I submit when I enter? 

The entry system asks for your Mile Swim Pace, if you don’t know, then please go to the swimming pool and time yourself swimming for 1 Mile (1 Mile = 1600 metres or 64 lengths in a standard 25 metre pool or 32 lengths in a 50 meter pool) this will then give you a good indication of what pace you will be able to sustain over the entire swim but please bear in mind the maximum pace that we require for swimmers to be capable of over the full 5.25 mile swim is 65mins per mile on Saturday and 55mins per mile on Sunday.

Many people tend to underestimate their Mile Swim Time or add a slower Mile Time to ‘play it safe’ which creates problems in the first half of the event, as you will start your swim in a wave and the water safety team cannot move away from the wave for individual swimmers who are swimming faster than the others. In simple terms, if you add a time which is too slow for your ability, it is likely that you will be asked by the water safety team to slow down in the early part of the race and your finish time will be affected. The event is designed in a way that the waves start to merge once swimmers get passed halfway and it is then less of an issue but please try to submit an accurate mile pace based on a 1 mile swim.

If you need to change your Mile Time before the event then simply log back into the entry system at the go to ‘My Area’ and ‘ Tickets’ then find the relevant Ticket and go to ‘Changes’ and ‘ Edit Questions’ and the first question you will see is for your Mile Time – you can change your Mile Time up to one month before the event.

On the day the more relaxed pace swimmers (65 min/Mile Time on Saturday and 55min/Mile on Sunday) start first and approximately every 20-30 mins a slightly faster paced group will enter the water.

You will have a much better experience during the swim if you submit an accurate Mile Swim Time and you are grouped correctly.

What time does the event finish?

Swimmers will arrive at the finish between around midday and 3pm on Saturday and slightly earlier on Sunday up to approx 2pm and prize giving will be held as soon as possible after the last swimmer is out of the water, back at the event HQ

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?

For Saturday swimmers we have a cut-off swim time of 65 minutes per mile, so with the staggered starts we expect 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!
For Sunday as the max pace is 55 minutes per mile the starts will be similarly timed and staggered which will allow for a slightly earlier finish with the sweep boat making sure that everyone is out of the water by 2pm, this will still allow for plenty of time for the more relaxed pace swimmers to enjoy the scenery.

When does registration open?

Registration will be open on Friday evening from 1730 – 2030hrs, and on Saturday morning from 0700hrs, to allow the early swimmers chance to register on either day.
There will also be Registration available for Sunday swimmers at the above times and up until 1800hrs on Saturday then on Sunday morning from 0700hrs.

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.
