Stop after 50% of race is done

[PantherSports21]

I am wondering if I can set up a rules instruction in Guardian so that the trigger is stopped after e.g. 50% of estimated race length is done?

Thanks for your help!

Try this, just a case of chaning it from a 'back' to a stop rule type and adding the longer distances if required
