AP McCoy is regarded as the greatest jump jockey who's ever sat in a saddle, and this fascinating documentary follows his last year on the track.

As he passes his 40th birthday, which is pretty ancient in jockey terms, McCoy remains incredibly focused on winning, breaking records and maintaining his position at the top of the pile.

Meanwhile, his wife Chanelle would like nothing better than for her husband to retire, get more involved in family life, and enjoy the trappings of his success.

As well as getting behind the scenes of his daily routine of being driven to a racecourse, weighing-in and (almost always) winning, Being AP delves into this man's obsessive nature, his unquenchable desire, and an almost child-like disdain for any other activity.

Even more revealing are the scenes at home. Here is a man uncomfortable with domesticity (nothing new there, really), even though he and his family live in a mansion and have a walk-in wardrobe about as big as a decent-sized apartment.

At one point, McCoy asks Chanelle what he would do if he retired from racing. When she replies, "There are plenty of lunchboxes to pack and bins to take out," he recoils in horror.

At the racetrack, Chanelle is terrified that AP is going to suffer a fatal or life-changing injury, so her desire to see him retire is understandable. His nonchalant attitude as he rattles off a lengthy list of broken bones, scars and injuries tells its own tale.

Being AP is a splendid study of a great sportsman, and shouldn't be limited to a horse-loving audience. I went into the screening in a blissful state of ignorance about his achievements, and came out in awe.
