David Smith, from the Fen Centre organising committee, believes about 1,000 people took part in skating at Upware on Sunday
Keen skaters have been making the most of the recent cold snap by taking to the ice after flooded fields in the Fens froze over.
Hundreds of people flocked to Upware, near Wicken, Cambridgeshire, over the weekend.
Fen skating takes place when a meadow floods and then freezes, meaning the ice is very shallow – unlike with frozen lakes or rivers.
David Smith, 57, who helps organise the activity, said: “It was wonderful to see so many people, from children under eight to people over 80, enjoying a day’s skating.”

Mr Smith said Sunday was a particularly busy day and believed there were “at least 1,000 people on the ice” by the time he arrived at 09:30 GMT.
He is part of the Fen Centre, the organising committee for racing on the Fens and a sub-committee of British Ice Skating.
Skaters came from “a radius of up to 100 miles (160km) away, a few come from London”, said Mr Smith, from Sutton.
“I met people from Bedford – the chance to skate on the Fens is a real magnet.”

The Fens of East Anglia, with its rivers, dykes and flooded meadows, makes ideal skating terrain – if the conditions are right
Roger Giles, 87, from Welney, Norfolk, who helped co-ordinate Fen skating for many decades, said: “You need at least 2in to 4in (6cm to 10cm) of ice to be able to skate.”
But he predicted the icy conditions had “nearly come to an end”.
Competitive skating began in the Fens in 1879, and since then speed skaters have vied for the world or Fenland title whenever a Fen has frozen long enough to allow the championships to be held.
“It was wonderful to see so many people come out and enjoy something I’ve been doing for 45 years,” said Mr Smith.
“The ice came and it was perfect because it was on a Saturday and Sunday, when people are off work and children not at school.”

The ice is very shallow indeed, unlike with frozen lakes or rivers, making it far safer than other forms of outdoor skating
