Maryland is the capital of the equestrian world this week, beginning today with the Carte Blanche Show Jumping World Cup in Baltimore and followed by three days of Olympic trials in Westminster. Also, the Maryland Hund Cup steeplechase will be held in Glyndon, Saturday.

Depending champion Hugo Simon of Austria heads the list of 29 riders from 10 countries competing in the World Cup. Events begin with the Welcome Stakes at 4 p.m. at the Baltimore Civic Center.

Simon won the inaugural World Cup last April in Gothenburg, Sweden, and is slated to ride Gladstone and Answer, both of whom are 11-year-old chestnut geldings.

Other entries include British veteran David Broome, the top European qualifier who will be up on Queensway Big Q and Queensway Sportsman. Bernie Traurig of Hartland, Wis., the top North American qualifier, is slated to ride Southside and Eden Vale.

At the three-day competition beginning Friday at Ships Quarters Horse Farm, a total of 56 horses from the U.S., Canada and Japan have been entered in the open intermediate class, which is one of three trials for the U.S. team.

Defending champion Dosdi will head a field of seven steeplechasers in the 84th running of the Maryland Hunt Cup Saturday at the Glyndon course outside Baltimore. Post time for the four-mile, 22-jump marathon is 4 p.m.
