Swim along this beautiful stretch of the River Thames through the organic pastures of Oxford University land. This swim is aimed at all levels of swimmers. Either you’re looking for your first taste of river swimming or you’re training for an Iron Man and would like to swim the full distance before your main event. The swim starts at Eynsham Lock and finishes 4km downstream at Kings Lock. And because it’s with the flow of the river it makes progress a little easier.
Sunday 16th June 2019
The 4k Lock to Lock swim from Eynsham Lock to Kings Lock follows the River Thames downstream through the picturesque landscape of Wytham Woods and Oxford University pastures. Swimmers should be familiar with open water swimming and be able to complete the 4k distance. Wetsuits are mandatory unless you gain our permission in writing before the event. If in doubt please contact us regarding your previous open water swimming experience.
We swim this stretch of the river regularly. The flow differs from one day to the next based on factors such as rain fall, opening of locks etc. The flow is generally fairly slow but we have noticed a difference of 15 minutes on our total swim time dependent upon flow rate. Up to date information can be found at http://riverconditions.environment-agency.gov.uk/
Everyone swims at a different pace but the fastest recorded time for this event is 42 minutes. Our more leisurely swimmers enjoy the swim for up to 2 hours 45 minutes.
The Environment Agency, who grant us permission to run the Lock to Lock event, ask that swimmers stay to the right of the river wherever possible. Boats and other river users also navigate on the right so, as river users, we need to adhere to the same rules. There are occasions when it is safer to swim closer to the middle of the river: There is one tight corner approximately 3k along the route where the water gets very shallow on the inside bend making it possible to touch the river bed. On some of the tree-lined sections of the course there can be obstacles such as submerged branches and tree roots that could be dangerous or cause injury if snagged. Our safety kayakers will help alert you to these obstacles en-route.
Wetsuits are mandatory for this event unless you are an experienced open water swimmer and have our permission, in writing, in advance to swim without. Please contact us at email@example.com for permission.
Yes, the event will either be timed.
We aim to have results available online within 48 hours of the event finishing.
Safety is our utmost concern. We have safety kayakers paddling with you along the length of the course and we have spotters on the shore. We also have medics at the event should you require any medical attention.
We hope that everyone will have trained enough to complete the full length of the course. However we do realise that this may be the first time some participants have swum this distance in a river and we will have support boats nearby should you experience any difficulties. There will also be exit points along the course.
The water will be tested to environmental safety standards before the swim. In 2015 the water test passed with a “high” cleanliness rating.
The water temperature will very much depend on weather conditions leading up to the event. In September 2015 the water temperature was 15 degrees centigrade.
Public Health England publish a leaflet on the risk of illness when open water swimming, which can be viewed here: https://www.gov.uk/government/publications/swim-healthy-leaflet. We always follow these guidelines and have never become unwell during or after swimming this stretch of the Thames. Public Health England recommend...Before you swim to cover cuts, scratches or sores with a waterproof plaster before swimming, consider wearing appropriate protective clothing such as a wetsuit, gloves and/or protective footwear. While you are swimming try to avoid swallowing and/or splashing water into your mouth, observe local safety advice. After swimming ensure you clean your hands thoroughly with soap and water after swimming and before handling/eating food, thoroughly clean cuts or abrasions using soap and water, handle your wetsuit with care after use, rinse it with clean water as soon as is practicable after swimming, clean with detergent and rinse as advised by the manufacturer, always wash your hands with soap and water after handling or cleaning your wetsuit and allow the suit to dry thoroughly before reuse.
Siemens Magnet Technology, very close to the start of the swim, allows us some parking spaces. There is also space for additional cars on the road leading up to Siemens. We request, where possible, that you car-share to limit the number of parking spaces being used. We cover the cost of the car park so parking is free for our competitors. There is additional, overflow parking nearby.
There are 3 options...
a) We recommend that you take the shuttle bus from the end of the swim back to Seimens car park. Please pay for the shuttle when you register. You can buy more than one bus ticket if a friend would like to walk the towpath to watch you and travel back with you.
b) You can leave a car somewhere in Wolvercote then car share to the start (Eynsham Lock). Be aware there is very limited parking at the start and a toll to pay on one of the bridges.
c) When you finish the swim you can walk back to the start, however it is a 4km walk along muddy tow paths and can take well over an hour.
We get nervous too! There will be toilets at the start and end of the swim.
Registration will take place in the field next to Eynsham Lock. There will be a changing tent next to registration. Put a towel any clothes you would like for the end of the swim in a bag and hand over to our marshals. Your bag will be transported to the end of the swim ready for you to change into. There is a changing tent at the end of the swim too.
Yes - You’ll need your flip flops (or similar footwear) when you get out of the river at the end of your swim as you’ll need to walk along the corner of a field. You’ll be given a bag to put your flip flops in at registration. Put your flip flops in the bag and hand to one of our marshals. Your flip flops will be waiting for you at the end of your swim.
We advise you to put your car keys into your clothes bag. We have a system in place to ensure that you are the only person who can retrieve your bag at the end. Please note that we cannot accept responsibility for any loss or damage to personal items left in your car.
When you’ve finished your swim and changed into your warm clothes we invite you to enjoy a fresh coffee or tea in your souveneer mug with a slice of homemade cake – included in your ticket price. Dependent upon the number of competitors at the event you should have to wait no longer than approximately 15 – 30 minutes to get a bus back to your car.
For this particular event we are able to get insurance for 14’s and above however, in addition to signing the waiver when you buy your under 18’s ticket, you must send a letter from a parent/guardian stating that your child is a strong swimmer, swims regularly with a club and has previous necessary open water experience, swimming against adults. This must be signed and either posted to Swim Oxford, 11a Shipton Road, Woodstock, Oxon OX20 1LW or scanned and emailed to firstname.lastname@example.org. This must be received by us no later than one week prior to the swim event date.
Yes you can swim in the Thames any time, and we do, which is how we discovered this lovely stretch of the river. You can also run 26 miles through the streets of London free of charge, any day, but still thousands of people choose to enter the London Marathon each year. Our event enables you to swim in an organised swimming event and to enjoy the experience with other like-minded people. Our ticket price covers a multitude of items including… car parking, water testing, event insurance, rescue kayaks, rescue boat, paramedics, swim caps, souvenier mugs/medals, tea/coffee/cake, timing chips, WC hire, registration and changing tents, river licenses etc. It also covers the time it takes us to actually organise the event and liaise with local land owners and the Environment Agency, and our annual costs of publicising the event and maintaining our website.
