Miss Jessica Llewellyn(5)

The bulk of her racecourse experience has come through her partnership with trainer Bernard Llewellyn, and those 14 rides together account for the whole of her current record. Family or professional ties aside, that kind of consistent booking from one yard gives a young jockey the rhythm and racecourse time that experience alone can provide. The "(5)" after her name is worth explaining too — it's a claim, meaning she carries 5 pounds less weight than the race requires, a concession the sport offers apprentice and conditional riders to help them compete while they're still learning the craft.

One winner from 14 rides is a modest return, but it's a start. Every jockey with a full book of rides and a big reputation began with a record that looked exactly like this.
