A fair while ago I wrote an FP1 Revision Relay for the old specification.
I have recently written one that targets the Vectors content of (predominantly) AS-Level Further Maths. 
The intention is that it is used like the UKMT Senior Team Challenge relays, in fact that is how I used it last week with my Year 13 Further Mathematicians. Students work in pairs – one of them answering the odd numbered questions and one of them answering the even questions and passing the solutions between them.
If you would like to give it a go download the file to use here.
