The Mares' Novices' Hurdle debuted in 2016, expanding the Cheltenham Festival to its longest-ever format with 28 races. This addition created more championship opportunities for female horses. The race honors the legendary Dawn Run, the only horse to have captured both the Champion Hurdle (1984) and the Cheltenham Gold Cup (1986).
The first three runnings were sponsored by Trull House Stud and therefore up until 2018, the race was known as the Trull House Stud Mares’ Novices’ Hurdle.
This race quickly became a showcase for the powerhouse duo of trainer Willie Mullins and jockey Ruby Walsh. They achieved a remarkable winning streak, particularly with the phenomenal mare Quevega, claiming six consecutive victories from 2009 to 2014.
Mullins' dominance extended beyond Quevega, as he went on to train other winners like Limini (2016), Let's Dance (2017), Laurina (2018), and Eglantine du Seuil (2019)
Trainers from England have occasionally broken through, with wins like Roksana (2019) for the Skelton team and Marie's Rock (2022) for Nicky Henderson.
From 2020-2023, the brilliant Honeysuckle, also trained by Willie Mullins, stamped her authority on this race with four consecutive victories.
