I don’t think this race will count for World Rankings:
“From 1 January 2023, World Athletics will only process results (for all its statistical purposes including World Rankings) which have been achieved in a competition listed in the World Athletics global calendar. This list now also includes National Permit competitions across all disciplines which have been proposed for inclusion by Member Federations as per the World Rankings Competitions Application Procedures which can be found here.”
Currently, I don’t see the 2024 Houston Half Marathon listed on the calendar and I’ve been told it needs to be listed on the calendar for a minimum or either 60 or 90 days. (However, I can’t find confirmation in any rule book of the minimum amount of days needed, but regardless, if this race isn’t on the calendar, it won’t count- according the WA website at least).
