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 with your helmet. 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.

White swim caps will also be available at the Information Desk for less-confident swimmers.
