You may well find it quite difficult to get an in focus shot. The bikes are traveling that fast the camera will struggle to track focus, and you will find it difficult to keep them in the frame. A longer lens will help with fast subjects as you can get the shots from further away, its much easier to get focus.
If I was trying to do that I would be looking to just set the camera on manual, as fast as you can get the shutter on about F8 by pushing the iso as high as you find acceptable. Then I would pre focus and set the camera on high speed drive and hit the button just before the bike arrives. I did this a few years ago at the waterworks and got some reasonable shots with a 7D and a 100-400.
The other thing you can do is vary the height of the camera. I took some shots on the corner at the end of the straight after Parliament square, cant remember the name now, with a wider lens. I was lying on the ground with the camera under the fence. That got some more shots I was pleased with, not the quality you will get with your kit, but they float my boat. Wish I was there with you
