Agents with clients heading by road to Heathrow or Gatwick airports this Sunday should warn them to prepare for severe disruption as several highways, including the M25, will be closed or heavily restricted due to the Olympic test event, the London-Surrey Cycle Classic bike race.
The 140km road race will start in central London and travel in a loop via Richmond Park, Hampton Court and Box Hill to Surrey and back.
Affected roads, including stretches of the M25, will be closed for the majority of Sunday.
Tube services will be running, but they could be busier than usual.
