The RunSignUp API has been extended to allow for better searching and sorting for races with a date range. We have added last_end_date and next_end_date to the response. We also added an option to search on start date only. If you add “search_start_date_only=T” to the URL, you’ll only get races based on the start date.
This is useful for our technology partners and affiliates who display races placed on RunSignUp on their calendars – like RunningIntheUSA.com and many others.
