Sunday's King of Speed cycling event.

Butterfield won last year's competition in which riders can reach speeds of up to 40 mph.

However, the women's event will have a new winner with last year's victor Isla Dixon having left the Island.

The 250 metre event, which includes a number of elimination rounds, begins at the Cenitaph on Front Street with a rolling start to Parliament Street where the flag is dropped and the race for the finish line at the Flagpole gets underway.

Meanwhile, a change to the main races of the day sees the introduction of the devil-takes-the-hindmost format meaning any rider who gets lapped will be pulled automatically from the event.

National cycling coach Greg Hopkins said: "This has the effect of making the race faster and more exciting, particularly if there is a breakaway.''
