All five of Great Britain's Olympic eventing horses passed the final inspection at Greenwich Park.
Mary King (Imperial Cavalier), Tina Cook (Miners Frolic), Zara Phillips (High Kingdom), William Fox-Pitt (Lionheart) and Nicola Wilson (Opposition Buzz) all presented their horses in the main arena under a leaden sky with heavy drizzle falling.
And they were all given the green light after the punishing cross-country test that saw 15 riders fall.
Britain currently lie second in the team competition and are bidding for an 18th post-war Olympic medal later this morning.
Germany, the current leaders, also saw their five horses pass untroubled.
But there was a worrying moment for third-placed Sweden when Ludvig Svennerstal's horse Shamwari was held for reinspection, before passing.
New Zealand also had a 100% record, including their 56-year-old individual gold medal contender Mark Todd with NZB Campino, but there were casualties elsewhere.
American Boyd Martin's horse Otis Barbotiere was withdrawn after visiting the holding box, while a combination of horses from France, Canada and Belgium were not presented for inspection.
