On a conference in Headingly area of Leeds. May have a fews hours free time. Any good trails not too far away which you would recommend? Much appreciated.

Depending on 'what you are into' - you should be able to happily spend an hour or two at Stainburn (see www.singletraction.org.uk) which if you have a car with you isn't too far.

If you are around either Tuesday or Thursday evenings take a look at the North Leeds Thread.
