The Run4Fun(Colchester) is a 2.5 miles (4.0 km) fun run around Colchester Castle Park and attracts around 500 entries each year. Run4Fun entrants tend to come from local Colchester businesses and individuals. Between 2002 and 2008, Run4Fun has contributed almost £54,000 to the chosen charities of the Mayor of Colchester, averaging more than £8000 each year. All the money goes to the Mayor's chosen charities for that year.
