ZRL S3 #4 – Greatest London Flat
Course Notes – 1 Laps + Lead-In – 31.1km
One of the flatter courses and one that has been ridden before in ZRL. The only significant ‘climb’ appears once during the Lead-In, as you turn right off the Embankment and head up to Trafalgar Sq. This comes at about 3.5km. That incline is repeated at 27.4km
Outside of this incline and a couple of rises out of tunnels, you should be able to safely carry out turns on the front, fully utilising a TTT rotation during the London section. After the tube, there is a drag past the bottom of Box Hill to watch out for and of course the escalators coming back into London
Try to keep the team together until at least Box Hill, but you may wish to go without if a split occurs at after this point or on escalator.
Why not see how fast you are likely to go with the Zwift DS Time Predictor – this will give you a time for your 4 (min required) to 6 riders, based on the best WTRL TTT racers. It will also tell you the power that each rider should be using on the front and for how long, based on their Weight and Height.

|3.5km||500m||5%||Drag up to Trafalgar Sq – Agree w/kg for group!|
|10.3km||400m||3-4%||Continue turns but light riders may need to modulate effort|
|11.6km||500m||2%||Rise out of tunnel – stand and push to maintain momentum|
|14.5km||3km||Really flat section all the way to the tunnel – efficient turns req.|
|18.5km||400m||5%||Past base of Box Hill – splits common here – decision time!|
|Consider a blob and w/kg target until 21km|
|22.5km||15%||Escalators, stand and drive into them – flat section after to reconnect|
|27.4km||500m||5%||2nd time up to Trafalgar – if you have more than 3 then big effort and risk split.|
|30.3km||Build for Sprint Finish – Race Each Other!|
