But Edgar's pleasure in qualifying must be tinged with anxiety since she is suffering from a pulled muscle between her ribs, which left her doubled up in pain after competing in one of yesterday's classes.
The injury was sustained on Wednesday when Edgar, having cleaned the windscreen wipers on the horses' lorry, misjudged the distance from the bumper to the ground.
Edgar, 22, won the Grade A Jumping on Everest Unique. She also had the fastest time on Surething in the Leverton Speed Classic, won by John Whitaker on Everest Hopscotch.
Liz Edgar, Marie's mother, kept the family in the prize- money by finishing runner-up to Whitaker in the speed contest on Everest Radiant. Marie may borrow the mare for tomorrow's Horsemaster, which carries pounds 10,000 in prize-money plus a car if anyone succeeds in winning with four clear rounds.
