Thought it might be an idea with the amount of tracks closing now that we could list available practise tracks with open times cost and your view of the facility.

There is Ashdown Farm on the A417 near Blewbury Oxfordshire
Open on Sundays from 10 til 4 but if you want to go there in the week give them a ring and they will try to accomodate your needs. Call Jamie on 07725199303.
Track can get busy at times, but it costs £20 to ride all day as there are no sessions. Selection of jumps and twisting sections and a huge hill with big airtime at the top.Also a kids track and an intermediate track.
Solos (£20), Quads(£25) and Sidecars(£30) allowed.
Track is getting graded regularly now, its the best I've seen for a while

went there last year, abit far but well worth it, the bit through the woods is great.
cant remember how to get back there though, any chance of a post code?

Not sure of postcode but here are directions.

How to get there:

From the North: Take the M40 and then join the A34 at Junction 9, heading south. Head west on the A4130 turning onto the A417 at Harwell. Follow east to Blewbury and carry on toward Streatley. Take the track signposted to 'The Downs' which is opposite Halfpenny Lane (which goes to Moulsford) and the Cholsey road. Follow this track which turns into the Fair Mile and as the ground opens up the course is on the right through the gate

From the South: From the M25 join the M4 at Junction 15. Exit at junction 12 (Theale) onto A4 towards Newbury at A340 roundabout head for Pangbourne then onto the A417 to Streatley, track is about three miles out of Streatley.

From the East: Along the M4 again, off at J12 Theale then as above.

From the West: Along the M4 again turning off at junction 13, north on A34 then right at Chilton heading for Upton and onto the A4I7, head south about one mile to The Downs'.
