Ealing Half Marathon is returning to the boroughs streets on Sunday, with more than 5,000 runners expected to take part.
The race, supported by the Gazette, is now in its second year, having been launched in 2012 as part of the legacy to the London Olympics.
Runners will set off at 9.15am from Lammas Park, on a 13.1 mile single lap route taking in parts of Ealing, Montpelier, Pitshanger, West Ealing and Hanwell, before returning to the park to cross the finish line.
Lammas Park will also play host to the race, retail and charity village.
Race director Kelvin Walker said: Last year over 4,500 people signed up to run our inaugural race and we are delighted that so many runners are returning. We are grateful for the support of everyone involved in making the event happen and we wish all the runners good luck for Sunday.
Organisers suggest good cheering points for spectators, outside of Lammas Park, are Uxbridge Road, Pitshanger Lane, Drayton Bridge Road and Cuckoo Avenue.
They also hope runners will beat last years charity fundraising effort and raise more than s150,000 for the chosen cause, Epilepsy Action.
Other charity partners include Tearfund, Cape, Ealing Samaritans, Ealing Centre for Independent Living, Imperial College Healthcare Charity, Shooting Star Chase, The Gabrielle Gray Foundation, Raise the Roof Kenya, and St Mungos.
The race has the support of five Anglican churches alongside the running route who will be manning the Volvic water stations, and the Ealing Half Marathon Pasta Party also returns to St Peters Church, in Mount Park Road, tomorrow (Saturday), where runners and volunteers can gather after the 4.30pm service for a bowl of pasta costing just s2. All proceeds go to the church.
