London 2012: The long journey from bid to Games

The demand for tickets was phenomenal and unprecedented. It is impossible to satisfy everyone, but opinions differ over whether the system used to allocate and sell tickets was actually the “least worst”, as Locog insist it was.

As for security, recruiting double the number of venue personnel than was originally budgeted for, was certainly not Locog’s finest hour.

Locog has also faced strident opposition from some local residents in Greenwich over the use of Greenwich Park for equestrian events

And there is a continuing agitated dialogue over how the Olympic Games Lanes will operate.

In truth, the greatest challenge still facing Locog is transportation because no amount of modelling, planning and predictions will really tell it what is going to happen when hundreds of thousands of people head to the park from all over London on peak days.

Flow charts, presentations and reassuring words will count for nothing if the Jubilee and Central Underground lines fail and the public are unable to hand their highly prized tickets in at the door.

Then there is the question of what happens to the Olympic venues once the Paralympics end on 9 September.

The Olympic Park Legacy Company is the body responsible for working out what should happen with all the buildings and facilities in the park.

Its brief is to find cost effective ways which have a lasting benefit to the community and for sport.

The company’s biggest headache is the Olympic Stadium. Four bids are under consideration, with West Ham United being the most high profile.

The football club will have to be prepared to share the stadium – possibly with a concert promoter. It will remain in public hands and have to keep the athletics track.

Still, IOC president Jacques Rogge told Prime Minister David Cameron earlier this week that he was “happy” with the way London had gone about its work, but he admitted that “the proof of the pudding will be in the eating”.
