Theres one starting in Delamere Forest near Chester on 2nd March. Is that in Liverpool?
I ran the Delamere course yesterday and videoed it (quality is quite poor). The route is as I ran it before Christmas with the organiser. I don't know if this is the confirmed route, the map on the parkrun website is slightly different. I can't see it starting in the car park as there is a bottleneck and bollards and then at the far side of the mere it takes you on to the road which is not necessary.
EDIT: route description does say it starts next to car park. it also mentions "a nasty (but very short) little hill." which I wouln't call a hill, it's more of a incline and it's not really nasty. (18:15 on vid)
