The lenses I have available are as follows:

Canon EOS450D
Canon 18-55mm
Canon 28- 135mm
Sigma 105mm
Sigma 50mm
Tamron 70-300mm

Cheers

No expert Graham but i am assuming no tripod as kids and other people about. trucks not too near for H & S of yourselves so 70-300 Tamron but prepare to step up ISO for shutter speed handheld. Rule of thumb no VR is focal length = shutter speed required hand held so 300mm = 1/300th i would set camera to Shutter Priority, then dial in the ISO until you get the camera settings and f stop you require. Bear in mind to freeze very quick action around 1/1250th or higher required which is why these people who do motorsport photography have £5k lenses to give performance required.

Would take the 28-105 as thats got a useful range if you get any close up chances say walking about before or after.

The speed thing Denny mentioned is a GREAT rule of thumb!!!

But that only applies to 35mm cameras,you need to take into account the crop factor of you camera (think Canons are usually 1.6) so at 100mm it's actually 1/160th,so at the long end 300mm would be 1/480th (or obviously the nearest value ABOVE available).

Not sure what the noise is like on the 450D so would probably shoot at ISO 400,but fire a few shots off at higher settings!!! to check on the computer later to see how it performs??? as this will give you more of an idea for future shoots...

Of course with a SONY the VR is in camera so you can get away with any lens at lower shutter speeds! But yes i forgot the crop factor. Still chuffed i eve knew the rule of thumb!
