A bottle of champagne was presented to each of the 17 drivers who took part.
The grooms and drivers spent about 10 hours polishing the horses, harnesses and vehicles, before putting on their finest driving livery. Not all drivers in the World Championships took part in this presentation.
Weber, 35, drove his four bay warmblood geldings put to a black dog cart presentation vehicle, finished with maroon-and-white pinstripes, with his wife sitting beside him.
Fairclough, 52, also drove four warmbloods (the wheelers being full sisters), put to a formal black Kuhnle presentation vehicle. Owner Jane F. Clark sat beside him.
Johnson, 46, drove a shooting brake.
Medal competition begins today (US time), with the first of two days of dressage. The challenging and exciting marathon will be a feature of the Games on Saturday, and Sunday's obstacles phase will climax the Driving World Championships and be the final competition of these World Games.
Total attendance through Day 11 of the 2010 Alltech FEI World Equestrian Games is 323,145.
