NOTE: All timings may be subject to change. Any changes to the programme will be highlighted at registration, please register in good time. Locations can be found on the site map below and will be signposted on the day. The triathlon starts will be staggered to maintain a safe number of competitors on the course, you will be given an approximate start time on the morning.


Registration will open at 7:20 and take place in the school quad where refreshments will also be available. At registration you collect a race pack containing your race number.

  • Race Number – This should be worn on the front of the shirt that you will be wearing for the cycle and run, if you have a race belt you are welcome to use them. (There will be race belts available for sale on the day)

You will also have your race number marked on your upper arm so marshals can identify you during the swim. Arriving with plenty of time is one of the easiest ways to keep pre-race nerves down, giving you time to set up and even walk the course beforehand.

Once you have registered you will be directed over to the transition area, which will be next to the swimming pool. Only competitors are allowed into the transition area, this is a rule set by British Triathlon, marshals will be in the transition zone to help competitors should they require it.

(7. TRANSITION AREA CONDUCT: 7.1 General Rules: m.) Helpers, friends or family members are not permitted in transition areas.)

We would also ask that once you have finished your event you get the attention of a marshal in transition who will safely assist you with removing your items from transition, this is for your safety and the safety of other competitors who may still be racing.

Please see the map below for directions for the poolside spectators area and competitors entrance to transition.


This is where you will collect your bike or trainers following the swim or bike legs of your event. There will be different exit gates depending upon which leg of the event you are entering, these exit points will be clearly marked. These entry and exit points will also be explained to you during the pre-race briefing, and our marshals will be more than willing to help.

Transition can get quite hectic, therefore only athletes and officials are allowed into the transition zone. There will be marshals on hand to assist you with placing your bike in the correct position and to help sort out the things you will need to leave in transition.

In brief:

Things to leave in transition before the start:

  • Bike (handy to have a water bottle on your bike ready)
  • Helmet
  • T-Shirt with race number attached to the front or a race belt (there will be race belts available for sale on the day)
  • Running shoes (and cycling shoes if you use these)

Things to take to the swim start:

  • Swim cap (if you want to wear one)
  • Goggles (if you wear them)

In transition you will find bike racking with numbers, you will be given a transition location number on the front of your race pack envelope. This will be your area to place your bike and lay out your t-shirt, shoes and helmet, please ensure you place your items neatly and do not throw items onto the ground as they could become tripping hazards.

NOTE: Your requirements will vary depending upon which event you have entered, although the marshals will try to help as best as possible, it is your responsibility to know how many laps you’re doing and to count how many you have done.

Course Routes:


Please report to the poolside at least 10 minutes prior to the swim time you will be given on the morning. Please make sure you have your goggles and swim cap ready if you require them.

You will be asked to line up based on your race number, when your time comes you will enter the water using the steps at the shallow end of the pool and wait to be told to start. There will be no dive starts.

Long Course: The pool will be split in half with two wide lanes, with 3 competitors in each lane swimming 16 lengths, totalling 336m.

Open and Closed Road: The swim will work on a snake basis. Up one side down the other, under the rope and again for the next length. You will do 8 lengths of the pool totalling 168m.

There will be a spectators area accessed via the Dell gate due to the other pool area access points being used for the transition zone entries. This is shown on the Quad to Transition direction map above.


The cycle is either 6km for the closed road or 11km for the open road. Both will start at the exit of the swimming pool and head out towards the top of the school. Turning left and going down through the school car park. At this point those on the open road will leave the school grounds and follow the map below. You will do two laps of the main loop section of the bike course shown. You will return to the school and join the internal loop again.

The route turns left out of the school and then left again onto Lower Road. With a 180* turn at the first round about. You will then go back past the school into Little Bookham. Straight over the first roundabout and take a left at the squareabout. This takes you onto the main loop. Past Bookham Station and back round to the main road. Lap 1 turn left and go again, lap 2 turn right and head back down the hill before turning left onto Manor House Lane and back into the school.

The internal lap may be a little congested and can be quite quick, so we ask you to be extra vigilant and safe. Any dangerous riding will result in you being asked to stop the race.

Below shows the internal loop which is approximately 1km long. You will do 6 laps of the course before returning to transition for the run course.

Important notes:

  • Helmets must be on and fastened before your touch your bike.
  • You must not mount your bike until you have crossed the Mount Line.
  • At the end of the bike course you must dismount at the Dismount Line.
  • Do not unfasten your helmet until your bike is back on the rack in transition.
  • You are subject to the highway code at all times
  • Within the school grounds please ride safely and think of others
  • It is your responsibility to count your own laps, not that of the marshals.


The run route is a mix of tarmac and grass. You will exit transition on the opposite side to the bike in, taking a left turn across the manor house lawn, down behind the school. From there you will run round the back of the hall and up onto the playing fields. At this point you will be merging with other runners from your left. The course sticks to the extremity of the school grounds and will loop adjacent to the internal bike course.

Closed Road: Will run 2 laps as shown on the map below, totaling approximately 2.4km. At the end of the second lap you will enter the finishing circuit.

Open Road: Will run 3 laps of the course on the map below, totalling approximately 3.5km. At the end of the third lap you will enter the finishing circuit.

Long Course: Will run 4 laps of the course on the map below, totalling approximately 4.2k. At the end of the fourth lap you will enter the finishing circuit.


The route is a little undulating, but everyone will be pleased to hear there are no big hills. At the top of the loop you will turn around and head back into the school playing fields. Down the hill and towards the running track. Lap two will then repeat, after which you will enter the inside lanes of the running track for half a lap of the track and finish on the home straight.

Remember to smile!

Medals: All competitors will receive a medal as a recognition of the effort they have put in.

Timing: The timing will be carried out manually on the day, giving competitors an overall time. If you want split timing we would advise parents or guardians to do this for their children. We will also have a video camera recording the finish to assist with timing and post-race media so make sure you smile!

Refreshments: Food and drinks will be available to purchase throughout the morning from the school quad area. This is a great way to refuel after your effort and for your supporters to keep up their energy levels so they can cheer louder.
