Work on the arena for this summer's London 2012 test event in Greenwich Park is all going to schedule, organisers told journalists at a press briefing today.
Contractors are busy putting together the large platform south of the Queen's House where 2,000 people will be seated to watch the Greenwich Park Eventing International in July.
Hundreds of specially strengthened legs are being laid down with the platform segments fitting on top.
The modular nature of the platform makes it easy to put in and take out, said organisers, and it can be used for a variety of purposes - Olympic gold medallist Usain Bolt recently ran a race on the very same platform that is now being set-up in the park.
Work will soon begin on the cross country course and from June 1st, most of the eastern side of the park will be inaccessible apart from the playground and Flower Garden.
Tickets for the test event are being made available to local school children and to residents via a council-run ballot.
