A 400m pool swim, 25km bike ride and 5km run

Swim (400m pool)

The 400m swim is 16 lengths of the Triangle leisure centre's 25-metre, 8-lane pool. It's a 'zig-zag' swim, keeping to the left of the lanes, swimming two lengths then moving on a lane until you run out of lanes. Our marshals are on hand to help you all the way through - you can't go wrong! 

The Aquabike and Triathlon entrants participate together in the pool.

We offered a 200m swim in 2021 and would consider offering this in 2022 if there is demand.


Both transitions (changes from one discipline to the next) take place in the tennis courts next to the pool building. The transition area is supervised at all times to make sure your belongings are safe.

The main thing to remember is not to touch your bike until your helmet is safely secured on your head.

Bike (25km)

Both the Triathlon and Aquabike follow the same bike route. It's a one-lap, 25km course mainly on local roads, including some beautiful Sussex countryside.

The Highway Code must be observed at all times: any competitors ignoring this will be penalised. Drafting is prohibited: if you are overtaken, you must drop back to ensure there is at least a 10-metre gap in front of you.

Marshals will be positioned at all turns on the course to guide and assist you. There will be signs to warn traffic, but please take care as you make your way around the course.

After the bike leg, Aquabike participants will make their way through transition to the finish line to end their race, while Triathlon participants will go through transition ready to start their run.

Run (5km)

The run course is a flat out-and-back route through Burgess Hill and the quiet surrounding lanes.

There is a busy road to cross at Jane Murray Way: marshals will be on hand to guide you here. For the safety of all athletes, you must obey the marshals' instructions at all times. 

There is a water and feed station at half-way point, stocked with jelly babies and manned by our friends at Hurstpierpoint College.

The finish line is located in front of the leisure centre.
