Racing: Jumps fans will be hoping for a thaw on Tuesday as the current cold snap ensured a blank day of action on Monday.
With Market Rasen already claimed by frost on Sunday, Carlisle had pinned their hopes on an 8am inspection.
However, clerk of the course Jonnie Fenwicke-Clennell was forced to take an earlier look after temperatures dropped well below freezing overnight.
He said: "We have abandoned. We went down to minus five last night and it's still minus four at the moment. The Met Office predicts a maximum temperature of one degree and that's at 3pm, so the frost is not going to come out."
Lingfield continue to fly the flag on the all-weather but Tuesday's fixtures are already subject to checks. Staff at Sedgefield have covered a large amount of the track in a bid to beat the weather, but clerk of the course Charlie Moore will still have to take a look at 3pm today.
