sammyantha,
Provided you can get the necessary fall it will be OK. Make sure you fit an access T at the exit point so unblocking can be carried out if required.

fantastic thank you, what is a necessary fall?

sammyantha,
An absolute minimum would be 1 in 40, the problem you will have is supporting the pipe every 0.5m. You will also need to incorporate an Air Admitance Valve to prevent siphon action.
