Joined by their families and carers, the visitors enjoyed pedal cart races, power boat trips and lake cruises as well as sailing and canoeing, with many vessels specially adapted to accommodate wheelchairs.

HOAC principal, Jeff Creak, said: “We had an excellent day.

"There were queues all day for wheelchair rides in the multi and there was a lovely wind to speed the sailors around the lake.
“It was perfect weather, although a little more sun would not go amiss.”

He said the event, whichhas taken place for about 25 years is always oversubscribed.
“We hope to be allowed to offer this event to the community for many years to come but HS2 has just written informing us that they plan to obliterate the area, including HOAC,” said Jeff.

“I have written to the Greater London Authority and HS2 outlining why HOAC is special and asking why it could not co-exist with HS2.”

HS2, the £16.3billion rail line from London-Birmingham, will cross HOAC's lake on a 3km long viaduct that will make the centre unuseable.

The centre itself would also be cheek by jowl with a construction compound while HS2 is being built and the lake would be partly occupied by platforms used in building the viaduct (pictured, right, in an artist's impression) .
