The Grand National is the biggest betting race in the world. Run over four miles with 30 fences and up to 40 runners at Aintree, it is a unique test of stamina, jumping ability, and luck. For bettors, it is the ultimate each-way opportunity.
Understanding the Grand National
The race covers 4 miles and 2.5 furlongs over Aintree's famous National fences, including Becher's Brook, The Chair, and Canal Turn. The distance and obstacles make completion rates lower than standard races — typically 60-70% of the field finishes. This makes form analysis different from regular racing.
Key Selection Factors
Age Profile
The ideal Grand National winner is aged 9-11. Younger horses (8 and under) often lack the experience for the unique National fences. Horses aged 12+ rarely have the stamina for four miles at racing pace.
Weight Analysis
Horses carrying 10st 2lb-11st 4lb have the best historical win rate. The top weight (11st 10lb+) has an extremely difficult task over this distance. Lighter-weighted runners in the 10st range frequently outperform market expectations.
Previous Aintree Experience
Horses that have run at Aintree before — particularly over the National fences — have a significant advantage. First-time runners at Aintree face the additional challenge of navigating unfamiliar obstacles at speed.
Going Conditions
Heavy ground slows the pace and increases the stamina demands. Genuine stayers benefit from soft/heavy going. Good-to-firm ground (rare at Aintree in April) produces faster racing and favours classier types.
Each-Way Strategy for the Grand National
With 40 runners, standard each-way terms are 1/4 odds for the first four places. Many bookmakers offer enhanced terms — five or six places — making each-way value even more attractive.
Optimal Each-Way Approach
- Select 2-3 horses at 14/1-33/1 each-way
- Ensure each selection has different running styles (front-runner, tracker, closer)
- Calculate whether the place odds alone offer value against your estimated probability
- Use enhanced place terms where available
Form Analysis Checklist
- Has the horse run over 3+ miles successfully? — Stamina is non-negotiable
- Has the horse jumped well in recent runs? — Falling eliminates any chance
- What is the horse's handicap mark trend? — Improving horses are dangerous
- How does the trainer's National record look? — Some trainers specialise in this race
- Is the jockey experienced in the National? — Aintree knowledge matters
