Jamie Tse, 33, who suffers from multiple sclerosis, has done a dry run of the route she will take to two Olympic venues to see if she can cope with the travel to get to various events. Her boyfriend BBC journalist Clark Ainsworth accompanied her.
Miss Tse, who relies on a crutch, took a London Overground train from her home in Forest Hill for the Olympic Park at Stratford. The research scientist in neuroscience with King's College London had to retire at the age of 28 because of her condition and insists on walking "while I can".
Miss Tse said the infrastructure was "brilliant", with step-free access and lifts around Games venues, but her problem was the long distances she needed to cover on foot, for instance the platform at Stratford Underground station.
They took an escalator from the station and walked through Westfield shopping centre to reach the Olympic Stadium entrance. The 600-yard journey took her about half an hour, but during the Games a shuttle bus service near the station would cut her walking time.
Miss Tse's foot drops after walking short distances, increasing the danger of her tripping and falling. She said she preferred not to travel, and never alone, during the rush hour as it makes her "anxious" and she was therefore worried about overcrowding on public transport during the Games.
After an hour's rest the pair headed to St John's Wood, the venue for archery. Stratford Station was fairly busy and Transport for London thinks it will get busier as visitors notch up an extra three million journeys on the network, which caters to 12 million passengers a day.
The pair changed at Canada Water for the Jubilee Line to Lords Cricket Ground. St John's Wood does not have step-free access, but shuttle buses will operate from King's Cross station. But getting to King's Cross station would involve changing at busy London Bridge station, which the pair want to avoid.
It was a 400-yard walk to Lord's Cricket Ground. Miss Tse said her disability was not obvious and people were unable to comprehend why she gets tired easily, increasing her "stress levels". By this point she was very tired.
The walk took her more than 20 minutes and it took the pair four-and-a-half hours to visit both venues. As the Games begin Miss Tse anticipates the queues for lifts and waits at stations could be longer but she is determined to make the most of the events and said she would consider using a wheelchair provided at venues.
