What are the odds on the Grand National?

The average odds of a winning Grand National horse are around 20/1. 23 of the last 30 Grand National winners won at double-figure odds. One For Arthur in 2017, Tiger Roll in 2019 and I Am Maximus are the only single-figure odds Grand National winners in the last 15 years. 

For a long time, racing fans assumed horses carrying over 11st couldn’t win the year’s biggest jumps race. However, this trend is showing signs of reversal in recent years. Many Clouds carried the monster weight of 11st 9lb to victory in 2015. We’ve actually seen seven Grand National winners carry 11st or more in weight since 2009.

Grand National ante post betting tips & predictions

Remember, Grand National 2025 ante post odds are always subject to change as certain horses might not run, jockeys could make unexpected decisions over their preferred rides, and the conditions at Aintree ground will suit some horses more than others.

I Am Maximus is the current 2025 Grand National favourite, and this is no shock after the horse won the 2024 Grand National and also the 2023 Irish Grand National. The 7 year old is trained by Willie Mullins and we be hoping to join a very small list of horses who have won the prestigious race back-to-back.

Previous key trends

Due to course modifications, the last 13 Grand Nationals are the most relevant for key trends. With no race in 2020, here are the trends for the race winners from 2010 to 2023:

Grand National experience

Experience tackling the Grand National fences is another crucial factor that can affect the Grand National ante post odds. The Aintree fences are unique. Being made of spruce means they look different to fences at other courses. There are 30 obstacles over the two circuits of the course. The Chair and Water Jump are negotiated just once, while the other 14 fences are jumped on both circuits. 

Some Aintree specialists adapt to the fences well, while other horses underperform when jumping the unique obstacles. A horse’s temperament is important during the marathon Aintree contest. Coping with the atmosphere created by about 60,000 racegoers while tacking the unique fences is a tall task. Tiger Roll is the most recent multiple-time winner, claiming victory in the 2018 and 2019 Grand Nationals.
