The Jubilee Greenway will connect Olympic venues and historic landmarks
The Duke of Gloucester has toured a new route to encourage Londoners to walk and cycle across the 2012 Olympic park in east London.
The Jubilee Greenway runs from West Ham to the Olympic Park.
The 60km network of cycle routes and walk ways connects the nine Olympic venues in the capital, including Hyde Park and Regent's Park.
HRH Duke of Gloucester, who is patron of the greenway, hoped it would give people "the confidence to explore".
He said: "I hope a lot of people will try it. When it is finished they will perhaps visit a part of London they haven't before and enjoy it."
The Olympic Delivery Authority is investing £11.5m in travel routes to encourage people to walk and cycle to the games.
Paralympic champion Dame Tanni Grey-Thompson said: "The Jubilee Greenway is a wonderful opportunity for both residents and visitors to get fit in the run-up to the Games.
"I encourage everybody to look it up and start enjoying it now - being healthier is the best legacy we can give each other."
