Race Course & Options


The spacious transition area is located on the bank of the lake with all races starting in the vicinity of the transition area. 


The race starts with a rolling swim start and either a single or double lap of the 750m lake swim course depending on the race entered. Cut off 1h:15 for the swim only events 


The fast cycle course is mainly on rural roads, with either one or two laps of the 20km course passing through Sible Hedingham, Blackmore End and Beazley End. 


The run course for all events starts at transition and runs to the looped section of the course that laps at the church aid station. Once the required amount of loops have been completed, the run course returns to the finish. The distance of this out and back section has been taken into account of the overall distances. Please note the correct amount of laps for the race entered. The course is mainly paths and grassland with some road footpath sections. All competitors run the same run lap route, only the amount of laps changes as per the race entered. 

All races will benefit from chip timing.

On reaching the entry limit we will keep a small waiting list to replace those who have to withdraw.

All races will commence at 8am, all competitors will be registered before the race starts to minimise traffic on the bike route outside the resort.

Contingency Plan - Every effort will be made to put this event on where we reserve the right to alter, move the date and postpone as required. We would not normally offer refunds however if it is decided to do so these would be less the cost to the club for abortive fees, such as supplier deposits. The event is run by a local Triathlon Club rather than a business.  In the event of part of the course being unavailable to the organiser on the day, for reasons beyond their control, an alternative course will be provided to allow a competitive event to take place. Should we be unable to provide a suitable safe alternative course due to reasons beyond our control and the event be cancelled Born2Tri will not provide refunds. 

Withdrawal Policy - Born2Tri acknowledge racers will on occasion need to withdraw an entry through injury or other reason. The cut off dates for refunds will be 4 weeks prior to the race itself (23rd June 2024) where a refund will be made less a £10 administration fee. After this date there will be no refunds available. We will not be operating a roll over to an event in 2025 and so this will not be offered as an alternative to a refund at any time. After the cut off date. If the event is sold out prior to the cut off date, we will allow a transfer to another athlete of your choosing up until 2 weeks prior to the race. 

Due to the intense organisation that is required to put the event on, the cut off for changes and race entries will be 2 weeks prior to the event. There will be no changes permitted after this date to the race entry. There will be no entries on the day in 2024.
