Backtest a horse racing system on a season of real racing.

Set the rules

A model is the races you want: price, race type, going, runners, bot score, handicaps, class, course and days. Change a rule and the win and place rate update straight away. The scoring behind the horse racing ratings can be re-weighted too, under Advanced.

Or let it find them

Start from an idea, like short prices or chases, or tap Find the best rules for me. It tries every mix over the period you choose and fills in the one that won most often on enough picks.

Then use it

Name your model and use it. On Pro, your picks, daily email, win alerts and widgets follow it. Save as many as you like; one is in use at a time. See what each plan includes.

Past results never guarantee future ones. The model is for testing ideas, not a promise of profit. 18+, please gamble responsibly.
