Who was the top sire of event horses in 2015? No, of course it wasn't Avebury (pictured) as he's a gelding, but his breeding does offer a helpful clue as to who was crowned the number one event stallion of 2015...

British Eventing (BE) produces a multitude of fascinating breeding data every year in the autumn, which can keep even the most casual of breeding fans entertained for hours — presumably true geeks go into spasms of ecstasy when the lists are produced.

The main sire rankings are produced by adding up the BE points (awarded at novice level upwards) and foundation points (awarded from BE100 level downwards) won by each sire’s progeny in that year. Below we reveal the top 10 sires on the list and detail a few of their most successful offspring.

BE also produces a ranking of sires of young horses, calculated by adding up points won by four to eight-year-olds. This is a good pointer to up-and-coming stallions who will be influential in the future.

The organisation also updates its alltime sire rankings, its lists of competing stallions and graded stallions and mares, and the total number of registered offspring each stallion has.
