Participants need to register at the registration desk and rack their bikes in the transition area between 6am and 7am on the morning of the event. If you are local or staying over in the area, participants will be able to register between 6pm and 7.30pm the evening before. Each participant will receive a race pack at registration containing numbered stickers for their bike and helmet, a single race number for their clothing, a swim hat and timing chip.


Relay team entries are also welcome. When entering on-line, one person will need to register and include the names of all participants, their emergency contact details and any medical information. Just one entry fee applies to the whole team – you are only entering one race, after all. In our events, teams of 2 or 3 are equally acceptable. Teams will receive one race pack containing one race number.


The sea swim course is tidal and although the swim section will take place during slack water (the time when the water is not coming in or going out) anyone in the water after 25 minutes is more likely to feel the effects of the sea more than those who complete the swim in a short time. For this reason we ask that all participants are prepared properly for the swim. On this note we would recommend that you prepare for a swim length of 750m (although the course is accurately measured at 500m). We reserve the right to direct people back to the shore after 25 minutes for their own safety. There will be 2 (possibly 3) start times for the swim. Your swim start time will be provided in your pre race information sent out 10 days before the event.


A wet suit is compulsory if the water temperature is 14 degrees or below. Over 14 degrees and under 22 degrees a wet suit is optional. The sea temperature in early July is normally around 17- or 18 degrees. We would recommend using a wet suit as this will assist with buoyancy and warmth. If you don’t have your own wetsuit yet, consider whether you wish to hire for a season, just for the weekend or something in between.


The bike route is on quiet but open roads, a mix of coastal, suburban, green fields and sleepy villages. The course is relatively flat with only 139m of ascent in total over the 20km course with a mix of straights and corners to contend with. Each year we focus on areas where we can make the experience even better for participants and this year the bike course has been updated so that it is just a single loop.

Tri training


Oysterman entrants are eligible to add the Tri Training Day on Saturday 19th June from 9am-12.30pm for £10 when booking onto the Oysterman (otherwise the cost is £20). The training day is open to anyone still relatively new to the sport and with a focus on the Oysterman course. The morning will include skills, drills and tips on how to complete an open water triathlon as well as some of the more technical elements in each discipline.


Upon finishing all participants will receive a bespoke medal and a finishers performance t-shirt along with an immense sense of pride and satisfaction having competed in the Active Life Oysterman Triathlon. There will be an award ceremony at approx. 10.30am by the finish area. Prizes will be awarded for the top 3 male finishers, top 3 female finishers.



Homelessness has been rising steadily over the last 5 years with 1 in 24 people in some areas of the south east being classed as Homeless.

Porchlight support more than 7000 individuals and families across Kent each year. If you would like to support their work, when entering you will be asked if you would like to make a donation. Whatever you donate we'll match. 



With to the event being cancelled in 2020 due to Covid-19,  our COVID secure measures may need to be introduced if we are still in a pandemic. Further details will be provided in the pre event information if necessary.
