Red Marauder won the 2001 Grand National. Trained by Norman Mason and ridden by Richard Guest.

The jockey fell off at fence 14.
He hasn't. Detori is a flat jockey and doesn't do the jumps.
Surely the grand national - jumps (4M 4F) Possibly the ascot stakes - flat (2M 6F) The longest flat race under Jockey Club Rules is The Newmarket Town plate at 3M 6F. The Grand National is run under National Hunt Rules.
In 2011 the Grand-National winner was Jockey- Jason McGuire and the horses name was Ballabriggs, Oscar Time was second, Don't Push it in 3rd. State of Play was in 4th place, closely followed by Niche Market in fifth.
No female jockey has ever won the Aintree Granda National. Jenny Pitman and Venetia Williams both trained winners.
Northern Irish horse racing jockey Tony McCoy has over 3,000 career wins.
G. Stevens won the Grand National five times, in 1856, 1863, 1864, 1869 and 1870, and won the Kentucky Derby three times, in 1988, 1995 and 1997. Of course, it isn't the same G. Stevens; the Grand National winner was George Stevens and the Kentucky Derby winner was Gary Stevens. But it's probably the closest to an answer you can get, since no jockey has won both races.
