WHAT'S IN MY RACE PACK?
Your race pack contains all the essential items for your race, and you will pick this up either the day before or on the day from the Registration area within the ExCeL South Halls.
SECURITY WRISTBAND: This must be attached to your wrist and not taken off until you have retrieved your bike from Transition after racing. This wristband will be numbered to match your race number.
BIKE NUMBERS: Before the race, stick the three numbered stickers on your helmet (front, left and right) and the other around the seatpost of your bike. These should not be taken off until you remove your bike from Transition after racing.
RACE NUMBER: Your race number must be displayed on your back during the bike phase and on your front during the run. We suggest you attach this to a race belt to give you the flexibility to switch race clothing and easily swap the number from back to front.
RACE TATTOOS: These are to be applied to your body, you can chose whether they are applied to one on each arm or one on each leg or one on your arm and one on your leg.
TIMING CHIP: You must also pick up your reusable timing chip at chip collection within the registration area. In the preparation area, fasten your timing chip around your left ankle using the Velcro strap. Please do not remove your timing chip until you have completed your triathlon or you will not receive a result. We advise that you put your wetsuit over the timing chip strap. This will help to keep it secure in the water and prevents you from having to remove the strap in Transition. All timing chips must be returned once you cross the Finish Line – there will be a charge of £60 for any unreturned timing chips.
SWIM CAP: During the race pack collection process you will also receive a coloured swim cap. Please note that your swim cap may be a different colour to your race bib and wristband. Please ensure you keep hold of it for Sunday if you collect your race pack on Saturday. It is mandatory to wear the swim cap during the swim.
BIKE RACKING
Once you have collected your Race Pack, please enter the Transition Area to rack your bike. You will enter Transition at a designated entry point where staff will check your athlete wristband and make sure the stickers on your bike match to your athlete number.
Rack your bike in Transition in the position that corresponds with your race number. There will be signage at the end of each row that will have the number range for that row – find your numbers and rack your bike in that row. Volunteers and event staff will be on hand to guide you.
You can choose to place your swim-to-run transition kit safely under or next to your bike. Or you can wait until race morning to place it under your bike. Your helmet must stay in Transition with your bike once your bike is racked.
You may also lay out your bike gear (shoes, helmet, nutrition etc) under your bike to make your transition from swimming to biking more organised, which will result in a faster transition.

IS THE SWIM A MASS OR PULSE START?
Please arrive at the Swim start queueing area 20 minutes prior to your race start. Once participants have checked into transition, they should make their way to the start area at least 20 minutes prior to their race start to join the back of the swim start queue. There a race briefing will be given to you by a member of staff.
The queuing system will take you down to the dockside; where you will ‘walk’ into the water individually – one at a time. All waves will be pulse starts with participants setting off approximately every 2 seconds.
SWIM SAFETY INFORMATION
For many, the swim is the most daunting part of the race, but don’t worry! Our water safety team will be there to guide you and help if required. Please identify yourself to our swim start team who can provide additional support and guidance should you need it.
Please take your time entering the water via the pontoon ramp. Should you need a short time to acclimatise to the water temperature before you start swimming, please move slightly to the left to allow other swimmers to pass from behind.
The team, provided by Swim Safety Ltd, consists of fully qualified lifeguards in kayaks and rescue boats as well as bank-based lifeguards on the pontoons. All lifeguards are members of either the BCU Lifeguards or Surf Lifesaving GB. If this is your first triathlon, or swimming is not your strongest discipline, we recommend that you position yourself towards the back of the wave. It may add a few seconds to your time, but it will enable you to get into your rhythm and enjoy the swim more. If you do get into difficulty, lie on your back and raise your arm in the air, a kayak will come to you and if necessary, arrange a safety boat to take you to the water’s edge.
CAN I DRAFT DURING THE CYCLING LEG?
No drafting is allowed i.e. taking shelter behind or beside another competitor during the cycling leg of the race.
DO I NEED TO REMOVE MY WETSUIT AFTER THE SWIM?
The swim exit pontoon dips into the water so you can swim onto it before standing up. Lifeguards will be on hand to help you out if required. Once you have exited the water, you must remove your wetsuit before you re- enter ExCeL and climb the stairs back to transition.
A wetsuit bag will be provided to you – please put your wetsuit, goggles and swim cap inside this.
There will be a small changing area shielded from public view which is available for any participants who require this facility for religious or sensitivity reasons.
CAN I LEAVE MY BAG SOMEWHERE?
We recommend that all participants and spectators bring with them a small bag containing only their kit. Bags will be subject to random bag searches upon arrival. There is no general bag storage facility on site outside of transition provision for participants only.
WATER QUALITY INFORMATION
The water is tested against World Triathlon water quality standards; however, we would still advise you to be in good health and try to avoid swallowing the water in the docks. . Some swimmers may be more susceptible to infection through immune suppression. Swimmers are also advised that they MUST NOT swim with any open wounds.
In open water swims there are no walls to push off every 25m, so practice swimming the race distance accordingly prior to race day.
NB: Wetsuits are COMPULSORY for all participants. Water temperatures will be monitored on the morning of the event and if it is deemed too hot to wear your wetsuit due to the water temperatures we will inform participants at registration and participants should leave their wetsuits in transition.
