You turn off the A1 dead opposite Downtown (shop) just after BP garage heading south bound (or bottom of hill with Downtown on your right heading Northbound)
Heading Southbound you have to nip into a feeder lane on central reservation and cross northbound cariiageway.
The road isn't usually gritted but is wide enough for 2 lorries to pass and dead flat.
Turning to Arena UK is about 1/4 - 1/2 mile down on right hand side and signposted on brick wall bits at side of driveway. Drive down drive and head straight past indoor arena (on LHS) and parking is at back - parking good.
Not sure whether theres any snow left there but none in Peterborough now
