There is a tool to auto-assign racers to category on the Webscorer website:
Navigate to Organizers / My start lists
Click on “Post start list from RunSignup”
Enter the RunSignup race id & credentials
Click “Get participants from RunSignup”
Select “Sport type” and “Start fype"
Select “Create categories based on age = Yes”
Click on “Post start list”
Add your age groups
Click on “Save changes”
Click on “Map categories to age”
Use the tool to map ages to category
Click on “Save changes”
After the reg closes, you’d then follow these steps:
Navigate to the start list page
Click on “Edit race info”
Click on “Update list from RunSignup”
Click on “Get participants from RunSignup”
Click on “Save changes”
The mapping only needs to be done once. You can then proceed to download the start list to the app, ready for timing.
You can also download the preliminary start list to the app, and once the day-of-race reg closes, update the start list on the website per instructions above and them on the app, tap “Merge start lists” toolbar button on the “Start List” panel to get the day-of-race registrations included.
